摘　　要：通过不同分辨率和不同时相的遥感影像,包括高分系列卫星、Landsat陆地卫星、Sentinel-2卫星等数据,结合前人资料,采用遥感信息提取和目视解译等方法,对淠河流域(六安段)生态地质环境要素进行信息提取,主要包括地形地貌、土地空间类型、植被覆盖、湿地、净初级生产力等生态地质环境要素,综合分析了生态地质条件的类型、空间分布和动态变化,为下一步开展淠河流域生态地质实地调查工作提供方向,为国土空间生态规划、保护与修复项目实施提供技术依据。By using remote sensing images of different resolutions and time phases,including those from Gaofen-series,Landsat,Sentinel-2 and other satellites,combined with previous data,remote sensing information extraction and visual interpretation are adopted to extract the eco-geological environment elements of the Pi River basin(the Lu’an section),mainly including land form,land space type,vegetation cover,wetland and net primary productivity.This paper comprehensively analyzes the type,spatial distribution and dynamic change of eco-geological condition in order to provide a direction for future field investigation in the Pi River basin,and technical basis for ecological planning of the land,and for implementation of the protection and remediation projects.
