基于GIS的山地城市生态敏感性分析研究
GIS-based Ecological Sensitivity Analysis of Mountainous Areas
摘要
Abstract
Ecological sensitivity analysis is frequently used in urban planning.A typical mountainous city (Gucheng county) is studied.Five factors are selected to evaluate the eco-sensitivity,including slope,elevation,vegetation cover,geologic hazards,and buffer zone of rivers.Ecological sensitivity is classified into five grades,that is extreme sensitivity,strong sensitivity,moderate sensitivity,slight sensitivity and insensitivity.The overall ecological sensitivity is evaluated and displayed on space scale by using analytic hierarchy process (AHP) and spatial analysis in Geographical Information System (GIS).The area percentages of the five grades are 23.96％,13.56％,36.68％,17.26％ and 8.54％,respectively.Ecological function regions are determined based on the evaluation results and advice for each region is given respectively to provide the scientific support for urban planning and land use aiming to reduce the risk of ecosystem damage.关键词
