Evaluating the ecological capability of urban, rural and industrial development and estimating the current settlement of these areas using GIS in Larestan County, Iran
Abstract
The importance of using rational and systematic methods in the management and optimal use of resources, especially natural resources, is clear to everyone. Improper development of residential and industrial areas leads to the destruction of agricultural lands and natural resources and expansion towards vulnerable areas, such as flood basins and inappropriate slopes, which in fact causes the ecological balance and stability of the land to be disrupted. The necessity of evaluating the ecological capability of urban, rural and industrial development is to objectify the capability of the expected land. The purpose of this research is to evaluate the ecological capability of Larestan County for urban, rural and industrial development. In this regard, the county of Larestan was evaluated using information layers and summarizing them using GIS technology. The evaluation results were presented in two relatively suitable (2) and unsuitable (3) classes. In addition, in this research, the percentage of suitability classes in the estimation of the current establishment of urban, rural and industrial uses was done by superimposing urban polygonal layers, points of villages and industrial areas of the county on the ecological suitability map, and the status of these areas was determined. According to the obtained results, most of the urban, rural and industrial areas are in the third or unsuitable class. In the survey conducted in the rural areas of Larestan county, a large number of villages (83.33%) are placed in the third or unsuitable class, which are scattered throughout the county. 57.3% of the area of urban areas are placed in the 3rd or unsuitable class. The industries of Larestan county are mostly placed in the third or unsuitable class (76.92%), this actually shows that the establishment of industries in Larestan county has not been paid attention to the ecological capability and this can lead to environmental damage. This improper establishment shows that both the industries themselves may be harmed and the industries can cause serious harm to the environment.
