Abstract
Experiences acquired in the reorganization of the old structures and buildings of the countrysides and suburbs show that Iran and other countries in the world, have not been successful, because of the inability to build and define a perfect house. This research discusses about the proper indicators related to appropriate houses from the perspective of those who live in such areas. Descriptive and analytic methods have been used. North East outskirt of Mashhad was the study area because a large population live in this region. The question is: Why people prefer to live in a house with a yard instead of an apartment. In this study, 410 persons were questioned. The collected data through the years 1391 to 1393 were analyzed by SPSS software. The Study shows that age, the year of buying the house, the educational level and the type of house possession affects the suburbs population's views. Therefore, if the governments consider these housing preferences and divide those people into certain subgroups, providing accommodation for them would be more successful.

Abstract
In recent years with the development of cities coatings of the Earth's has changed surface. These changes have caused some urban areas to have a few degrees higher than the surrounding temperature. This phenomenon is known as thermal islands. Mashhad is one of the major metropolises in Iran with the problem of thermal islands. Various parameters affect the formation of thermal islands in this city that should be considered. In this study TM, ETM+ and OLI images were used to obtain surface temperature over the period 1987-2016. The study of temporal variations in surface temperature showed that in the studied period, thermal islands were transferred from outside the city to the city. The model for describing the temperature of the surface of the earth has changed and has diminished from the temperature of the city's moderate and cool temperatures, and in contrast, the amount of high temperatures (thermal islands) has increased significantly. The TOPSIS method was also used to obtain the thermal forming factors. 13 natural and human factors affecting the formation of thermal islands were identified. Each expert opinion factor was used to determine the degree of importance. According to experts, the distance from the sanctuary with a weight of %234 and traffic of %155 is the most important and the height with a weight of %022 is least important in the formation of thermal islands. The final results obtained from this model showed that the factors affecting the formation of thermal islands are well recognized and the temperature decreases with these factors.

Abstract
Urban development and air pollution are among the most important issues related to climate. The expansion of urbanization and urban development, population growth, industrial development and excessive use of fossil fuels significantly increased air pollution and it is more than the capacity of the environment. In our country, the emissions of air pollutants in some metropolitan areas have reached a dangerous level, Mashhad is considered to be the most polluted cities of the country in some days of the year. Nitrogen dioxide is one of the indicators of air pollution. In this study, the OMI data and atmospheric parameters such as wind, surface temperature, and horizontal visibility data for the period from 2004 to May 2016 were used to investigate the air pollution in Mashhad. The results show that the maximum (minimum) nitrogen dioxide levels occur in the cold (hot) season. The highest amount of nitrogen dioxide in January is equal to 5.56 × 1015 molec/cm2 and its lowest value in September is 4.18 × 1015 molec/cm2. Standard deviation of nitrogen dioxide also indicates that the greatest changes occur in cold seasons. Also, the results showed that the dominant wind in the city of Mashhad is from the south, and most of the winds are slow. Correlation coefficient of nitrogen dioxide with wind and surface temperature is -0.36 and -0.57, respectively, which shows the higher importance of temperature in nitrogen dioxide changes in Mashhad city. The correlation coefficient of nitrogen dioxide with horizontal visibility is -0.15, which indicates that with increasing nitrogen dioxide contamination, horizontal visibility decreases. Spectral analysis of least squares of the six and twelve-month periods of rotation was observed, they were also statistically significant. After eliminating the significant components of the time series of the average monthly nitrogen dioxide, the trend was calculated. The amount of nitrogen dioxide in each year for Mashhad was 2.41 × 1013 molec/cm2.

Abstract
The present study is descriptive-analytical and for the purpose of application. The main objective of the present research is to develop a combination of quality of life indicators for neighborhoods in District 2 of Mashhad. The required information was obtained from the municipality of Mashhad and the questionnaire was used. According to the population of Region 2 in 1395, which is 513365 people, according to the Cochran formula, 383 questionnaires were arranged. The questionnaire was completed after the preparation and implementation of experts' opinions by referring at the level of the studied sites. The required criteria were prepared and standardized in the form of spatial information in the GIS environment. Economic, social and access areas were selected as the main criteria for research and were identified for each of the following criteria. Subsequently, using spatial analysis and multi-criteria decision making model (ANP), the final quality of life index was derived from the integration of indicators. The results indicate a good quality of life in the central neighborhoods, and there are no marginal areas of desirable quality. It also increases the level of quality of life in the vicinity of the recreational centers and follows the spatial patterns. Part of the margin of the agent's neighborhoods, the martyr Basir and Hedayat, which are the marginal areas of the study area, are not in the best of all three territories; and other neighborhoods due to easy access to public services, including health services, training, and facility focus Modern welfare has a better quality of life than other neighborhoods, of which 11675700 square meters, which is equivalent to 30 percent of the area of the study area, has a very good quality of life. Also, sites that are very low in terms of economic and social indicators are moderate in terms of access. In the following, the results of spatial statistics tests (spatial spatial correlation and J statistics) indicate the distribution of the cluster model of quality of life. In other words, quality of life indicators do not have the same spatial distribution in the study area.

Spatial Zoning and Analysis of Urban Poverty via Spatial Analysis (Case Study: Mashhad City)
Abstract
Examining the degree of poverty in every community is the first step taken towards planning for fighting against poverty and deprivation. With understanding the poverty change process over time, planners can make the necessary decisions. The present study aims to investigate the spatial zoning and analysis of urban poverty in Mashhad City. To this end, necessary data were collected and employed from various sources. The final map was obtained from the integration and overlapping of effective criteria in urban poverty zoning using the experts' viewpoints and reviewing the research background with emphasis on GIS spatial analysis. According to the final map, 33.05% of Mashhad’s area enjoys very good conditions in terms of the study criteria of zoning urban poverty. This area covers Felestin, Sajjad, Goharshad, Razi, Baharan, Valiasr, Fareghotahsilan, Hafez, Isargaran etc. areas. The second rank (covering 18.75% of the city’s area), indicating the appropriate situation, includes Elahiyyeh, Janbaz, Tarbiat, Honarvar, etc. areas. The third rank (covering 19.28% of the city’s area) is in moderate conditions, including different areas of the city including Railway, Northern Tabarsi, Vahdat, Amir Abad, Keshavarz and Mo’oud areas. The fourth rank (covering 8.46% of the city’s area) is in the inappropriate situation, covering areas such as Sis Abad, Eivan and some parts of District 7.

Abstract
Identity, as a complex concept, influenced by a variety of factors, makes one thing distinct and unique. Meanwhile, the characteristics of the environment, habits, worldview, cultural characteristics, etc., have a growing influence on the formation of these indices of identity. In other words, this study seeks to investigate the hypothesis of the difference in attitudes of inhabitants of the eastern and western parts of Mashhad towards urban identity indices and, finally, whether the distinction is observable or not? The basis of this study is based on quantitative methods that have been used for research purposes, along with qualitative methods. The output of this discussion is to achieve the identity of the city and its classification according to the purpose of the study. But in the small part, the study method is based on the use of differentiation and logistic models to show the type and level of differences between the eastern and western parts of Mashhad. Based on this, the rank of indicators of urban identity components was obtained in the form of a questionnaire in two categories of eastern regions (regions 4, 5 and 6) and western regions (including 1, 9 and 11) from the residents' perspective. The completed questionnaires were entered into the statistical database and analyzed using statistical software such as Excel and Spas. Study shoes that: 1- Regarding the formic index, studies show that variables such as high buildings, traditional architecture and natural form of place are variables that cause segregation of residents of eastern and western parts of Mashhad. 2- The results in Function indices also indicate that variables of vibrant places, places with activities, boarding times, places with different uses, and safe places are meaningful. 3- Finally, regarding the semantic indices, the effective and differentiating variables in the eastern and western regions of Mashhad, including two variables of understanding the sense of pilgrimage and understanding the characteristics of Islamic culture. Accordingly, it can be said that the attitudes of residents of the studied areas are different from those related to the sense of pilgrimage and the characteristics of Islamic culture in their. the end

Abstract
Generally speaking the existence of metropolises, alongwith the high various business districts have led to high valume of travels to these centers.The density and separation of these centers brings about the increase and the decrease of the vehicles. The adoption of location determination strategies and that of the comunicational centers and the city activities has made the cities continue the developement process while cosidering the fairly service destribution and the spatial equalities.The goal of this research is the recognition and determination of the city spatial organization working centers and activity model and the relation of service functioning with one another so that the mono central and poly central cities can have a important effect on the destribution system and service centers and the vast changes of the citizens .The analysis method is a kind of quantity and quality one. In the quality part of that the descriptive statistics ( the geometrical presentation , graphical disparation, the centralism measures) and the Hansen Model. In the areas of planning, a great difference is seen in the levels of land uses so that the land use of higher educations in the western metropolitan city of Mashhad area is 84 percent while that of the eastern area is 3 percent. It is the same about the equipped medicinal, commercial and green space areas.Only in the areas of managerial levels there is a relative balance. Finaly the city is devided by three areas throughwhich while considering the employment , the developement potential and distance , the land use determining rate was found out.

Abstract
A new urbanism theory has emerged in recent decades in response to numerous urban problems of the twentieth century, with the goal of creating vibrant, compact, diverse and desirable cities in terms of work, walking, life, and transportation options. In view of the widespread acceptance of this theory among the Iranian researchers, the aim of this study is to assess the sustainability of organic and planned neighborhoods in Mashhad based on the spatial-physical indexes of new urbanism. In this regard, two neighborhoods, RahAhan (organic neighborhood) and the second phase of Rezashahr (planned neighborhood) were selected. This research method is descriptive- analytical and the mixed model of AHP and GIS has been used to assess the stability of two neighborhoods. Accordingly, the Sustainability Measurement Model was used as a hierarchy in the form of 7 physical-space indicators (type of road, pedestrian width, land use, area of lots, access to the center of the neighborhood, number of floors and access to public transport) . Tthe research results show that in Rezashhar, 68.43% of neighborhood area has moderate to high stability and 31.57% of the total of the neighborhood area is the lack of stability, and in RahAhan, 70.84% of the total of the neighborhood has moderate to high stability and 29.16% of the total of the neighborhood is lack of stability. Therefore, according to the spatial indicators of the new urbanism, the neighborhood of Reza Shahr is more unsustainable than the old neighborhood of Rah Ahan. Therefore, this study shows the richness of traditional Iranian urbanization and the superiority of old neighborhoods. So, it can be said that traditional and organic urbanization is a more appropriate basis for applying the new urbanism approach and this approach can be used in the form of urban regeneration.

Abstract
The present research is descriptive-analytical and in terms of its purpose. Data needed for research were collected by means of documentation (library, magazines) and field materials using a questionnaire. Using the Cochran formula, the sample size of the population was estimated at 383 people and the data were obtained using spatial analysis ArcGIS and SPSS software have been analyzed. In order to analyze the distribution of urban services, the index of access to urban services has been used, which is derived from land use plans of Mashhad city and municipal information and obtained from network analysis (ANP) and spatial statistics tests. Also, to assess the satisfaction of citizens from the distribution of urban services through a questionnaire and using one-sample T-test in spss software. Also, Gray Gray Analysis (GRA) method has been used for ranking the neighborhoods of the District 11 of Mashhad in terms of social justice. The final indicator of the distribution of urban services indicates the favorable distribution of urban services in the Daneshjo, sharif, Tarbiat, farhang, and parts of Azadshahr and Faroghottahsilan. As well as the neighborhoods of Ziba shahr, Shahid Razavi and parts of Faroghottahsilan and Azad shahr, they are in a disadvantaged position in terms of the distribution of urban services. Also, based on spatial self-correlation test, the pattern of indicators in the study area has spatial self-correlation and cluster pattern. The analysis of the distribution pattern of urban services in the District 11 of Mashhad using J statistics shows that the distribution of urban services in the study area has a high concentration of cluster patterns. Based on the analysis of the gray-matter analysis of daneshjo, Azad Shahr, farhang and Sharif neighborhoods, they have high levels of social justice, and other neighborhoods are ranked respectively. In the following, the results of t test indicate that among the neighborhoods, Daneshjo, Sharif, farhang, Tarbiat and Azad Shahr neighborhoods had the highest satisfaction with urban services. The neighborhood of Zibashahr has had the least satisfaction with the distribution of urban services. The results of all the models used in the paper are highly consistent and consistent.

Abstract
The study of meteorological characteristics and its variability is important in assessing the climate change impacts for water resources management. Trend analysis of hydrological and meteorological time series is a method for determining the change in climate variables that is performed with different parametric and non-parametric methods. In this research, the annual, seasonal and monthly trends were analyzed regarding rainfall and temperature time series for 1986-2017 in 28 stations of Kashafroud basin in the Northeast of Iran. For this purpose, the annual, seasonal and monthly trends were evaluated using non-parametric Mann Kendall and Pettitt test at 95% level significance. The results showed the trend for the monthly maximum temperature in spring and winter and also the annual trend for all stations was increasing, whereas the summer and autumn pattern differed. The trend of minimum temperature in all seasons and stations do not have a uniform pattern. The results of precipitation trend indicated that the annual precipitation of the basin had not changed and did not have a significant trend in 5% level of significance. Precipitation of the basin in the winter decreased. There was an increasing trend in the Southern half of the basin in autumn. The noticeable decrease of precipitation in winter season especially during January and February with an increase in November can be a serious challenge for water resource management of basin during the dry season.
