RESEARCH ON THE SUITABILITY EVALUATION OF CONSTRUCTION LAND IN SOUTHWEST MOUNTAINOUS AREAS OF CHINA: A CASE STUDY OF BAOXING COUNTY, SICHUAN PROVINCE, CHINA
Applied Ecology and Environmental Research
Currently, the threats of mountain disasters are continuously increasing due to the highly vulnerable feedback mechanism of mountain ecosystems, and the construction land use type is most strongly affected by human activities. This study uses multiple index coupling models to evaluate the suitability of construction land. The evaluation uses mountain disaster risk, topographic and geomorphic environments, hydrogeological environments, human activity factors and socio-economic factors as the
... factors as the suitability standards. We use geographic information system (GIS) technology to improve the evaluation model and establish a suitability map of construction land for Baoxing County, Sichuan province, China. This study indicates that the mountain disaster risk is the core factor of the suitability zoning of construction land in Baoxing County, wherein, the development suitability of construction land in the central sectors is relatively high while the mountain disaster risk is relatively high due to the high socioeconomic value of the disaster-bearing areas in the central sectors. The development suitability of construction land near the fracture zones and the natural reserves is relatively low.
