应用地理信息系统技术的地貌气候单位线汇流模型

Geomorpho-Climatic Instantaneous Unit Hydrograph(GIUH)Convergence Model Under Geographical Information System(GIS)

基于地貌气候单位线理论，结合地理信息系统的特点和优势，在计算机上根据地形图进行流域沟系图的绘制，并自动提取各种地貌参数，推导出一种地貌气候单位线汇流模型．经实例验证。

Based on the theory of Geomorpho-Climatic Instantaneous Unit Hydrograph,applying Geographical Information System, and derived from the topography map of study area, the hydrographic net map and all sorts of geomorphologic parameters were obtained by computer. A convergence model of GIUH was calculated. According to the test of reality example, the calculated result agrees with the observed data.
