| 摘 要： | 利用 PcRaster 的环境动态模拟语言，基于地图运算和网格之间水流运动的模拟，开发了水文过程模拟模型，选择 太湖流域上游的西苕溪流域进行试验，用实测资料对模拟结果进行了验证，结果表明模型模拟结果与实际是符合的．本 模型可以用于流域的物质迁移、污染物迁移、人类活动的环境影响变化等的模拟．在此水文过程模拟的基础上，只要叠加 网格上的物质产出率，就可以很容易得到子流域出口的物质通量的变化和其在流域上的空间分布，集成各个子流域过程， 就可以得到流域出口断面的物质通量的变化．

| Abstract: | Based on cartographical modeling and water routing between grids using PCRaster dynamic environmental modeling lan- guage,a hydrological model was developed taking Xitiaoxi as a test watershed.Water routings were divided into four type:slope, channel,polder and reservoir.Slope and channel routings were simulated by kinetic wave equations with Manning formula;accord- ant junction process of polder was simulated by pump stations locations;and accordant junction process of reservoir were simulated by operating curve of reservoirs.The connection of accordant junction types were carried through on grid cells according to adjacent relations.Compared with monitoring results,calculated results had a high resolution.The model can be used to model materials transform,water pollution,human activities impacts etc.just overly material output in the hydrological model. |
