以30 m分辨率的SRTM－DEM数据为基础，通过GIS的空间分析功能，首先对数据进行坡度分析，通过坡度分级法将山地与平原划分，自动提取出山地的信息，再运用碎斑处理结合TM影像对结果进行修正；其次，在ArcGIS的水文分析（ Hydrology）模块下对 DEM进行数字地形分析，提取流域特征。经分析得到了研究区域的山地及河网特征信息，并与实际地形及河流水系大致吻合，改进了传统手工和野外调查为主的提取方法，初步实现了山地、水系信息的自动提取，为研究区域社会经济更好更快地发展具有一定的参考意义。

With 30m resolution SRTM-DEM data, through GIS spatial analysis function, first of all, slope analysis for data, using the slope grading method Mountains and Plains division, the mountain of information automatically extracted, and then use of the por-phyroclastic processing and TM image correction results.Secondly, hydrological analysis module in ArcGIS under the DEM for digital terrain analysis, feature extraction watershed.By the analysis of the research area of mountain and river network characteristic informa-tion, and in accordance with the actual topography and river system is roughly, improved the extraction methods of traditional manual and field investigation.The mountain stream information can be automatically extracted;it makes a referential significance for the re-search of regional social economic development better and faster.
