【 摘 要 】

The methodology of mapping and areal drainage evaluation was discussed. Generalized operations have been described, such as GIS technologies for topographic data. They resulted in maps for erosion network, density and depth of erosion network, as well as land surface sloping and further total evaluation as a drainage parameter.
