Irregular and unstable urban development has increased marginalization, destruction of urban green areas and increased demand for urban land, which in itself has led to the disappearance of urban green spaces and land use change of such lands and is possible. Cause certain global environmental problems such as the formation of urban heat islands, because urban green space is one of the important models in achieving sustainability in urban space and the physical and natural fit of the city. At the same time, the protection of the environment and urban green space is the main pillar of sustainable development, which has been discussed in developed countries for decades and in recent years has been highly regarded by planners in developing countries. The present study, in terms of Weberchr('39')s applied and developmental purpose, is a descriptive-analytical descriptive survey or field study in which the researcher-made questionnaire tool is used and the existing maps of urban green space are used. The purpose of this study is to explain the role of green space in coastal cities in attracting tourists with the approach of sustainable environmental development in the coastal city of Noor, but in addition to the main purpose of the sub-objectives, the researcher The results also increase the per capita urban green space, increase the number of urban tourists, prevent environmental damage and increase the income of the citizens of the coastal city of Noor.

Cities occupy vast areas. These fields are composed of different topographic and morphological units. As cities develop and expand, their dealings with various units of topography and geomorphology and related topics increase. Geomorphological units are always associated with the dynamism of the natural environment. Any action for the development of cities in some way intersects with the mentioned dynamism and detachment, and consequently with morphological phenomena. In this approach, if some necessary principles and points are not observed, the morphodynamic balance of the environment will be disturbed and the great dangers of most of the equipment and facilities of the city will be threatened. Sometimes the intensity of morphogenesis is so high that it produces irreversible results. The present study is descriptive-analytical in terms of purpose and in terms of data collection method and in the form of a survey or field in which the researcher has made a questionnaire. The purpose of this study is to investigate the role of roughness in coastal city planning using a comparison of AHP and AHP FUZZY hierarchical analysis in Noor city. In addition to the main goal, The results showed that in the early stages of the planning process, simple methods can be sufficient when identifying development options as a focal point. Under these circumstances, the choice of advanced and technologically advanced methods does not necessarily produce different results. However, when planning needs to identify the spatial extent of the desired development area, it would be ideal to consider the intersection area proposed by both methods
