Analysis of the Limitations of the Physical Development of Cities (Case Study: Sardasht City)

The development of cities in mountainous areas is highly sensitive due to the geomorphologic and instability limitations of the slopes. Over the past few decades, due to the rapid growth of the population and the increasing urban-urban migration, attention to cities and their physical development has been considered as an essential element in many development programs at all national, regional and local levels. Because the lack of proper planning, cities have faced many problems, such as heterogeneous and heterogeneous growth, environmental problems, and so on. This research studies the challenges and barriers of physical development in Sardasht city. The research method is descriptive-analytic. The study of the physical development bottlenecks in Sardasht city has been studied over 40 years and during the period before 1981 to 2016. For this purpose, topographic and geomorphologic information layers were prepared using satellite imagery and field operations, and then, using Arc GIS ver.3.9, the physical development of the city was studied in different periods. The results show that the city of Sardasht faces a great deal of restrictions on the three directions of geographical location of west, north and east, and from the south there is a physical development on the land of agriculture and gardens. The results also show that from a total of about 3125782.1 square meters, 8.59 percent of the range of completely suitable places and 36.08 percent of the total study area included a completely inappropriate range. The above findings can provide managers of Sardasht city with the limits of physical development of the city and executive approaches to rational encounter with them.
