摘要
利用地理信息系统可以建立流域的数字高程模型，并与grid模块的水文表面分析工具结合，形成直观的流域环境三维显示，再通过计算、统计与分析，即可获取精确的水文因子数据，为进一步水文定量研究及应用提出了一种高效的方法。
A watershed DEM that can be created by GIS, hydrologic surface analysis tool of gridmodule and other tools of Arc/Info can be utilizted to display vislbly the watershed enviroment in3-D. This model can also get precise hydrologic data with calculation, statistics and analysis.These functions give one efficient approach to the in-depth hydrologic researches and applications.
