Abstract
Awareness of the status of vegetation, land use change and surface temperature in each region, and the timing and location of their changes over time are important for micro and macro planning. In order to make optimal use of land, knowledge of land use changes is necessary, which is usually possible by detecting and predicting land use changes. Measuring the role of researches and researchers has been instrumental in the study of natural resources, especially vegetation, surface temperature and user variations in each location, as well as the availability of information for different times for valuable studies. In this study, ETM and OLI were used to study the process of land use change, vegetation cover, surface temperature, and hazards caused by them in perennial seasons. The results show that the area of use changes over the period 2000-2010 has decreased the area of use of the developed area, agricultural and growing gardens and the area of land and rangelands. Artificial vegetation has risen in aggregate and rangeland lands are showing a decreasing trend. Due to the importance of vegetation and its role in reducing the temperature of the earth's surface, the trend has been decreasing in regions with intensive vegetation and high temperature. Also, in the period from 2010 to 2017, the range was further increased and the city's growth continued sporadically, causing environmental changes and rising temperatures in the city. The change in the city's increased range has increased environmental risks, including the loss of good agricultural land and the increase in the temperature of the city. Due to the fact that most agricultural land is located in the vicinity of the city under cultivation of saffron, which in the warm seasons does not have surface coatings, changes in the type of cultivation can also affect the temperature of the earth.

Abstract
The diversification of economic activities in rural areas is considered as a strategy where rural households increase their income sources. The villages of Saqez city, despite having high environmental potential and capacity in different sectors, such as agriculture, have a poor livelihood and economic status. Therefore, the present article seeks to answer the following questions: What are the appropriate strategies for diversifying economic activities in the villages of Saqiz? The present study was conducted through descriptive-analytic method. In a survey method, SWOC analysis model and QSPM evaluation matrix, we presented appropriate strategies. To design a strategic model and determine the ranking of factors 20 from experts and also to factor out the factors of 300 villagers in the area. The study sample is selected as sample. The results of the SWOC model show that the existence of an appropriate ecosystem in the region for tourism development, the existence of four climates in the region and the possibility of cultivation in each season, as well as the presence of the leading farmers in the region, are the most important strengths against the weakness of the financial and economic context of many Villagers and traditional exploitation are the most important internal weaknesses for diversifying economic activities in the study area. Also, the results of this model indicate that in the external environment 34 opportunities have been identified, the attention of the authorities to the conversion and complementary industries, the border area and the suitable field for exporting agricultural products to the Iraqi countries, are the most important external opportunities and in contrast to 36 challenges and limitations. The key factors of the migration and exodus of elite educated to Tehran and neighboring provinces, climate change and increasing natural hazards such as floods and droughts are the most important external barriers affecting the diversification of economic activities in the villages of the study area. Also, the results indicate It gives diversification of the activities of the economy The studied villages should be focused on strengths and opportunities.

Abstract
Change in precipitation features is one of climate change outcome. Change in precipitation amount, especially in warm season, may influences climato-environmental phenomenon as well as human activity. In current research the decadal changes of monthly precipitation over the Caspian coast of Iran territory was evaluated. Accordingly, a large number of rain gauge stations (385 stations), where rainfall is measured painstakingly, have been used. these stations are under the supervision of Meteorological Organization of the country and Ministry of Energy. Since the original dataset pertaining to the precipitation prior to 1966 had noticeable missing values, and the data after 2016 were not accessible, a continuous time period from January 1966 to December 2016 was selected. From the daily precipitation of aforementioned stations contour maps were created using an ordinary Kriging method. The spatial resolution of these precipitation maps was 3 km * 3 km. Our finding showed that during the under investigation period the maximum gradient of precipitation moved from coastal parts toward mountainous area. Decrease in the area with high precipitation and increase in the low precipitation area is an other prominent decadal characteristics. According to the previous study, these changes might attributed to changes in systems which effect precipitation in the Caspian coast of Iran (northward movement in polar vortex, sub-tropical high pressure and cyclone truck). In addition, increasing temperature trends in the summer tend to decrease temperature spatial differences. Therefore, the convectional precipitation during summer has been decreased.

Abstract
Based on the notions and assumptions of the discourse of “new urban regionalism”, there is a close relationship between the "spatial morphological structure" and the "spatial division of labor" in a megalopolis region, and solving existing problems in one without another is not possible, because they can either act in the direction of positive reinforcement and support, or in order to weaken and become an obstacle to each other; therefore, what is meant by the problem of achieving equilibrium and integration in the spatial structure and the functional system in a megalopolis region, will not be possible without recognizing the nature and relationship between these two. The reviews done the research shows that "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades has not been able to support each other and significantly reduce the spatial non-equilibrium in the region. Therefore, according to the results obtained in the framework of this study, the "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades (1345-1390), has been accompanied by a significant reduction in the spatial non-equilibrium in the region, though, the trend of transformations is on the move. One of the strategic implications of this is that the future issue of the Tehran's megalopolis region is to be more focused on the peripheral population poles and the improvement of the level of performance of the city itself in order to accept transnational functions and create alternatives and opportunities for roles and the tasks that will be assigned to them in the future. Just as in the prior years the industry sector has gradually shifted to the service sector, in the future it also seems necessary to give up the services sector to itself periphery and oppose the acceptance of the fourth sector of the global economy (such as; Information, communication and cultural economy).

Abstract
In many developing countries, including Iran, urban development is one of the most important factors in land use change. Most cities, in their turn, have caused the destruction of agricultural land and have been covered by urban expansion. This is a matter of economic and agricultural activity, especially in province like Gilan, due to temperate climate and fertile soil, which is one of the things that demands that appropriate planning prevent the uncontrolled expansion of these cities. In this regard, we aimed to study the land suitability analysis as a tool for planning and predicting an optimal urban development model in cities under the multi criteria decision making (WLC and TOPSIS models) in the GIS and based on various indicators at Foman and Shafts in western Gilan. The results showed that the output classification of the two models used was different, but suitable areas for urban development were overlapping in two methods. The most suitable areas for urban development are found in northern and eastern parts. Also, land use has the highest importance in zoning. Based on the results, the inner development of the cities is recommended as the first priority.

Abstract
The present paper deals with the analysis and analysis of spatial justice and its relation with social capital using descriptive-analytical research method. To assess spatial justice, the distribution of urban facilities and their per capita amount (per capita of religious, educational, medical, green, cultural, etc.) are used at local level. Then, they have been ranked by the multi-criteria decision-making method of Vicar County. According to the rates obtained from the vikor method and considering the final points, Shams Tabrizi and PehrAbad neighborhoods are in a state of affairs and the property districts, Sheikh Taj and TapaliBagi and Ohadi have a favorable situation. The low-grade journals are in the new textbook and informal settlements. In areas such as Jahangir, Daneshghah, Sahand, Valiasr, Azadegan, new structures have been built as residential settlements over the past two decades. In the second stage, in order to evaluate the social justice of social capital indicators, a questionnaire was used that 383 questionnaires were prepared in relation to the population of each neighborhood. Five key indicators (trust, partnership, engagement, membership and security) have been used to assess social capital. The results show that neighborhoods such as Shams Tabriz, Khaje Nasir, Khan, Seidlar and Daraie have the highest social capital. In the third step, Pearson correlation methods and weight geographic regression have been used to analyze the relationship between spatial justice and social capital. In this method, the correlation between variables is shown in the neighborhood level. Output layer The standardized residual geographic weighted regression analysis between spatial justice and citizens' satisfaction shows that in Shams Tabrizi, Azadegan, Khajeh Nasir 1 and 2, Sheikh Taj, Daraie, and Pasdaran, there was a positive spatial relationship. This means that the spatial development of these areas has a positive impact on improving the quality of life and social capital, the greater the spatial justice in these areas will increase social capital.

Abstract
The attachment to the place is the emotional relationship of the individual to the place, which is rooted in the person's past qualities and experiences that the place should be able to meet the needs and expectations of the individual, and also the place must meet the capacity to meet those needs and expectations. The attachment to the location is based on the cognitive, emotional, and functional interaction between individuals, groups, and physical-social location over time. The purpose of this study was to use the meta-analysis method to analyze the results of research on attachment to the place. In order to perform a meta-analysis, 75 researches were conducted in this regard. Among the 18 studies conducted during the years 2006-2019, in the field of attachment to the place were selected. In the first step, the evaluation of selected research, homogeneous assumptions and publication error was studied; accordingly, the findings indicated the heterogeneity of the size of the effect and the non-dominance of the published studies. In the second step, the coefficient of effect size was evaluated using the second version of CMA software. The results showed that the size of the effect or coefficient of influence of the identified factors is 0/376, which is evaluated according to the Cohen's interpretation system. Overall, the results indicate that the identified factors have a moderate effect on attachment to the location.

Abstract
The growth and expansion of the dispersed development pattern is one of the ways of settlement development that is shaped by a variety of factors, including urban management policies and approaches. Examine how the development of Tehran's metropolitan area has evolved over the last fifty years and what effective urban management policies and approaches have been and how it has influenced city development. This article deals with it. This research has been used because of the importance of the topic in a descriptive-analytical and practical purpose, based on library and documentary studies and in some cases field observations. In order to achieve the objectives of the study, three types of measurement models were used depending on the subject and variables of the study. In this regard, physical continuity in Tehran urban complex through Shannon entropy model, functional continuity through network analysis model (investigation of habitat and flow points and distribution and land use composition) and poor urban slope growth using Helder model The measurement is located. The findings show that: 1) dispersal phenomena have occurred in Tehran metropolitan area (Helderen and Shannon entropy model), 2) Tehran metropolitan area has been experiencing functional divergence (network analysis) and user distribution The services and services at the Tehran metropolitan level have not been uniform and balanced; and 3) the policies and approaches of urban management in successive years have had wide-ranging effects on spatial dispersal and unbalanced spatial development. Tehran's urban complex had.

Abstract
"Governance" is one of the basic concepts that has attracted the attention of geo-political scientists, and there are contradictory views on this concept, which is one of the main and fundamentally important foundations of the science of geopolitics. The rule of law over higher power and superiority imply that no other legal authority is superior to it. Since the study of sovereignty in political geography is very important, therefore, it is necessary to examine its dimensions and spatial levels. Political geography focuses on the study of phenomena, processes and political currents, and emphasizes their geographic and spatial effects. One of the most important studies in political geography is the study of the country. Each country is made up of three elements of "nation, rule and land".. The linking factor of these three elements is "sovereignty". In political theories, they regard the sovereignty of that government and do not attribute it to any government or government agency alone. At the same time, in no political theory, the notion of sovereignty is not absolute, and it is believed that sovereignty must be exercised within the constitutional framework and in accordance with the law. Land is the space of the state, which, with the spatial scope of the territory, determines the sovereignty of the state, and as the physical container, it includes the body of the political organization. The present article seeks to elaborate on the fact that "sovereignty has different dimensions and levels". The present research is of fundamental type and has been done by descriptive-analytical method. Data collection method is library and computer. Also, data analysis is also qualitative.

Abstract
Land surveying to increase crop production and productivity is nowadays considered as one of the alternative approaches in agricultural development and the need to address this issue especially in rural areas where their income is highly dependent on agriculture is of great importance. Is high. Agricultural development is one of the priorities of agricultural planning and requires such development to identify the effective factors that govern it. The purpose of this study was to evaluate and evaluate the environmental capabilities of olive cultivation in Tarom city and to analyze the location of its producing rural areas. Hence, from altitude, slope and slope status as terrestrial parameters and three climate parameters as relative rainfall, temperature and relative humidity data from 11 meteorological, synoptic and rain gauge stations with appropriate statistical period (1375-1395) and A common time base was used for climatic zoning. The results showed that Tarom city is in good condition for olive cultivation, 21.2% of the total area of the study area is suitable for olive cultivation, most of which is located in the middle districts of the city. Located in olive-growing lands, these areas produce 74.8 percent of the olive in Tarom, due to its olive-growing potential.

Abstract
Also, because of human activities and natural phenomena, the face of the earth has always undergone a change. Therefore, for optimal management of natural areas, awareness of the ratio of land cover/land use changes is a necessity. Therefore, extraction of land use maps as the most important goal in the management of the natural resource can be considered. The purpose of the present study was to evaluate land cover/ land use changes at the Rozechai Watershed during the period of 30-years 1985-2015 using Landsat 5 and Landsat 7 satellite imageries such as TM and ETM+ sensors; plus, land use maps were prepared using TerrSet software and object-oriented classification in 1985 and 2000 years. As well as the land use map of procurement by the geographical organization in 2015 has been used. The results show that rangelands level has the highest percentage among all land use types during the period of 30 years, but between 1985 and 2000, and 2000 to 2015, the level of rangelands has a decreasing trend indicating the destruction trend in the region of the replacement of moderate- poor rangelands and good rangeland by dry farming. Also, the tables of obtained from the error matrix indicate that the observed values in the diameter of the error matrix are much larger than the values outside the diameters. Thus, the overall accuracy for the years 1985, 2000, and 2015 were 97, 90 and 96 percent, and The values of Kappa index were 91%, 84% and 94% respectively, indicating a high degree of accuracy in the object-oriented approach to classification.

Abstract
Analysis of the views of urban buildings is important in order to identify effective components in the perception of the audience. By conducting studies on existing buildings, we can provide appropriate strategies for organizing urban views. This article tries to provide a framework for measuring urban streets from the perspective of the perception of citizens and, on the other hand, promoting the quality of urban views and increasing the perception of citizens. Based on the method of analysis, the study of global and internal studies of the conceptual model is developed, which provides factors affecting the perception of citizens from the view. Also, based on the studied method, the reliability of the Tehran Center's leaders, due to the presence of early qualities and emphasis on the presence of citizens' for the study, has been selected to provide realistic understanding of the factors affecting the perception of urban street view. According to field views, initial dialogue and conceptual model, targeted questionnaires were prepared and to find the hidden relationships of the variables, and the comparative comparison of citizens and experts to analyze the information of the questionnaires, SPSS software has been used. General components of perceptual modeling, from the perspective Architectural and urban design experts were measured and then based on the special model of the questionnaire, the questionnaire was developed. The questionnaire and interview were accompanied by the perceptions of the recognition and perception of citizens and directly with the audience of this axis. The goal is to identify the main components and prioritize perceptual components from the mental perspective of citizens. The results show that the main components of perceiveness of urban views, impact components, unity, coordination, attachment to location, diversity and attractiveness of the perception and recognition of the traditional view of the fifteen Khordads are effective.

Abstract
Land is the most important factor in the physical development of cities; land management has now become one of the most important concerns and concerns of local governments. Also, the sprawling growth of cities has degraded the environment and natural resources around the cities. Meanwhile, due to inadequate and accelerated decision-making, some of the inner-city and inter-contextual capacity of cities for development or redevelopment has been overlooked by urban managers. Cities play an important role in the economic growth of each country, with nearly 60 percent of the GDP of developing countries being produced in cities. They are the main engines of the growth of each country's national economy. The present study attempts to investigate the decision-making patterns of urban land policies in the physical development of Sari. The type of research method is descriptive-analytical and it is of applied nature. The findings of the study indicate that the lack of a clear vision and consequently uncoordinated policies and institutions, centralized and non-cooperative decision making, and excessive tenure without the necessary institutional capacity are the most important reasons for the inefficiency of urban land management policy. Therefore, the appropriate model of government policy in urban land management is integrated urban land management based on clear and necessary vision formulation. Expressing a one-piece strategic policy, and delegating part of the government's powers to the lowest level of local institutions with more specific capacity building, government intervention in the four areas of land management, land use, taxation and construction must be consistent and consistent. Since the government does not have the institutional capacity to perform such verification, it is limited to policymaking and oversight to achieve the policy goals and fulfills part of its verification duties in each of the four domains whilst capacity building the necessary training courses. It moves step by step with the policies adopted to the lowest level of local institutions

Abstract
The purpose of this research is to use granulometric analyzes in desertification studies in Gonabad city, To achieve this goal, after the preparation of geomorphological maps of the region, 14 sediment samples were taken from the erosion-sensitive facies of the region. In the laboratory, a series of sieve with a diameter of 2000, 1000, 500, 250, and 64 micrometers, and a container Gatherings of sediment smaller than 64 μm were screened. The results showed that the highest frequency of particle diameter in sand samples was in the 250-225 micron class. And, given the average particle relationship with their transport intervals, it can be concluded that the distance between the particles was close to a point. Variants of different samples varied from 1.502 to 1.319. The most prevalent plots of ridge and the smallest slopes with low slope were the highest. In surveys in the skidding section, precipitates were mostly positive tilted, indicating the prevalence of fine particles in the region.

Abstract
The main aim of this paper is to determine the capable areas for cultivating pistachio through considering of Geo statistical Analysis the major effective factors. The necessary climatic daily data of weather stations For the 300 synoptic stations, the station was set up by 2016. The topographic data include relief, slope, aspect, and TIN layers extracts from 1:250000 topographic maps of the region. The maps of land use and vegetation land cover were prepared from the 1:250000 maps of national soil and water Research Institute. The spatial analysis facilities of GIS were utilized for numerical calculation and the spatial geodatabase of the region was established. Then spatial and description data was entered into the data bank. Finally by overlaying analysis in ArcGIS, cultivated area was classified according to its capabilities. The results showed that 707273/88 KM2 Of the area (43%), Not suitable for spreading pistachio cultivation (Including altitudes and urban use and steep slopes, seaside and riverside streams, shoals, saline and swampy lands) and 585130/39 KM2 (35/57%) From the country of Iran Area Including plain areas and agricultural use) was recognized as suitable for the expansion of pistachio cultivation. These areas are located in the east and south east, center and northeastern Iran.
