RCINFO在流域水文分析中的应用
he application of ARC/INFO in watershed hydrology analyses
将地理信息系统(GIS)与流域研究相结合。首先建立了吉林某山区的数字高程模型(DEM)，然后运用ARC/INFO中的表面分析功能，实现了GIS在流域水文分析中的应用。对所建立的山区DEM模型进行坡度、坡向、流线和流域等分析，并在此基础上预测降水的汇流方向，计算流域面积，取得了较好效果。
bstract: In this paper Geographical Information System (GIS) and watershed studies are combined. Firstly, we build a Digital Elevation Model (DEM) for a mountain of jilin province, and then carry out the application of GIS in watershed hydrology analyses using the surface analysis function of ARC/INFO. Analyze the slope gradient, aspect, streamline and watershed based on the DEM model that we built before; and based on these, we predict the conflux direction after precipitation; calculate the area of the basin. The results are satisfied.
