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.

As cities develop and expand, their encounters with various topographic and geomorphological units and related issues increase. Geomorphological units are always related to the dynamics and dynamism of the natural environment, and any action taken in the direction of the development and construction of cities in some way intersects with the aforementioned dynamics and dynamism and, as a result, with morphological phenomena. In this encounter, if some essential principles and points are not observed, the morphodynamic balance of the environment will be disrupted and major risks will threaten the majority of urban equipment and facilities. The purpose of the present study is to investigate the role of unevenness in coastal city planning by comparing the two analytical hierarchy process methods, AHP and AHP FUZZY, in the city of Noor. The research method is descriptive, analytical and field-based in terms of applied and developmental purpose and in terms of data collection, in which the researcher-made questionnaire was used as a tool. The result of the sensitivity analysis showed that AHP is sensitive to uncertainty in the decision model; However, the comparative analysis shows that the differences between the criteria rankings in the two models do not necessarily result in the selection of different options (as focal points), but rather differences in the spatial extent of the selected options are more important. The findings provide a new direction for the selection of MCDM methods for urban planning. If the planning objective is to identify priority areas for development as focal points, then simpler MCDM methods such as AHP should suffice; but in more detailed planning where the identification of spatial boundaries is required (such as determining the master plan), a multiple approach using two or more MCDM techniques would be ideal.
