| 摘 要： | 介绍利用地理信息系统软件ArcGIS生成水系密度图的思路和方法。文章以DEM数据为基础,利用ArcGIS中的水文分析功能自动提取水系。水系经过与网格相交、重新统计总长度、连接等操作,最后得到水系密度图。以徐州地区为例,说明该方法的通用性与可行性。

| Abstract: | This paper introduced a method of using the geographic information system software ArcGIS to generate water density.The paper was based on DEM data and drainage was automatic extracted by hydrologic function of ArcGIS.Drainage through the intersection with the gird,recounted the total length and join operator,and finally got water density map.We took Xuzhou as a case to illustrate the method＇s versatility and feasibility. |
