绘制水系网及汇水盆地的计算机实现

Drawing Drainage Networks and Drainage Basin Networks with Computer

利用水流向最陡方向的基本原理编制了计算水系网及汇水盆地的程序，实际计算了某地区的水系网及汇水盆地网，计算结果可方便地进入ＧＩＳ。

A program is written to calculate drainage networks and drainage basin networks on a land surface based on the principle that water runs down the steepest slope orientation. The drainage networks and drainage basin networks of a certain region is calculated. The networks map can be used conveniently with GIS.
