Ecological Suitability Evaluation of Construction Land Based on GIS: A Case Study of Yongzhou City

Ecological suitability evaluations of land use are often conducted as an important reference when formulating urban and rural planning and land use policies. This study selects five indicatorstopography, hydrology, transportation, land use, and ecosystem The College of Forestryservicesand uses the Analytic Hierarchy Process (AHP) and GIS spatial analysis to evaluate the ecological suitability of construction land in Yongzhou City. The results show that the construction land in Yongzhou is mainly located in areas of moderate suitability, with the most suitable and moderately suitable areas together accounting for 51.55% of the total area, indicating good overall ecological suitability. The areas of basic suitability and unsuitability are mainly steep hill and mountain areas, which are prone to geological hazards. The unsuitable areas are primarily nature reserves and national forest parks, with high vegetation coverage and steep slopes, designated as restricted development zones. It is recommended that develop moderately in the Xintian-Ningyuan line and northern areas to achieve a coordinated development of urban growth and ecological conservation.
