摘　　要：为了对淮河淮滨以上流域进行径流模拟,构建了适用于该流域的分布式SWAT模型,采用泰森多边形法产生子流域的面雨量,并以径流资料对模型进行率定和验证。结果表明,采用泰森多边形法处理降雨数据的模拟精度明显高于采用代表站法的模拟精度;SWAT模型对于平水年的模拟精度优于丰水年和枯水年,但对多峰的复杂径流模拟精度不高,说明SWAT模型产、汇流模块不够精细,难以模拟复杂的径流情况。To simulate the runoff in upper area of Huaibin Station in the Huaihe River Basin,the distributed SWAT model suit- able for the situation of Huaihe River Basin was established. The Thiessen Polygon method was used to obtain the areal average precipitation of sub - basins, then the model was calibrated and verified with measwred runoff data. The results show that in pro- cessing the areal average precipitation, the forecast precision of Thiessen Polygon method was much higher than that of the repre- sentative station method. The forecasting precision of normal years was higher than that of wet and dry years by SWAT model, but it has lower accuracy for complex runoff such as multi - peak flood, which indicates that the present version of SWAT model is not elaborated enough to simulate the complex and extreme hydrologic regimes.
