摘　　要：近年来,生态环境问题日益突出,生态环境敏感性分析变得非常重要。基于GIS技术的生态敏感性分析评价比传统的分析技术更精确、高效、智能化。本研究针对甘肃省陇南市实际情况,建立了生态环境敏感性指标体系并进行分级,利用DEM、现有地图资料及ENVI、ArcGIS软件计算植被覆盖度、坡度、降水量、高程、土地利用类型等敏感性因子。研究了将GIS空间分析技术用于区域生态环境评价中的理论方法和技术流程,并对影响该区域的主要生态因子进行了单因子评级和综合性评价,得出图例结果。Ecological and environmental problems have become increasingly prominent in recent years,environmental sensitivity analysis is very important. In the disadvantages of traditional ecological sensitivity analysis techniques more and more prominent,while the ecological sensitivity analysis based on GIS technology assessment is more accurate,efficient,intelligent. In this study,the Longnan City Gansu Province,established a system of environmental and ecological sensitivity index were graded using Dem,existing map data and ENVI,ArcGIS software to calculate the vegetation coverage,slope,rainfall,elevation,land use type six sensitivity factor. Studied on the GIS spatial analysis techniques for the evaluation of regional ecological environment theoretical methods and technical processes,and ecological factors affecting mainly carried out in the region of a single factor rating and a comprehensive evaluation of the results obtained map.
