摘要
介绍了TOPMODEL模型的结构及其产汇流计算原理,分析了地形指数在TOPMODEL模型中的意义,并介绍了地形指数的计算方法。将TOPMODEL模型应用在修河水系的万家埠流域的径流模拟中,DEM分辨率取为500m×500m,时间步长为6小时,并与新安江模型作了比较分析。
The paper introduces the structure of TOPMODEI and the principle of runoff yield calculation, analyses the sens of topographic index in TOPMODEI, introduces the method of calculating topographic index, TOPMODEI is applied in run off simulation of Wanjiafu river basin in Xiuhe river, The DEM resolution 500 m×500 m, the time step length 5h, TOPMODEI is compared with Xinanjiang model.
