| 摘 要： | 基于DEM构建数字流域水文模型，在此基础上，利用新安江模型作径流计算。利用陆面模式SSIB中大气动力阻抗法计算蒸散发的方法改进新安江模型的蒸散发计算，从而改进新安江模型对流域出流量的模拟，得到更为合理的陆面水文模型。以安徽水阳江流域为研究区域，利用改进前后的新安江模型进行径流模拟。结果表明，对新安江模型蒸散发计算的改进提高了模型对径流量的模拟效果。

| Abstract: | Digital basin model is established on the basis of raster DEM data. The Xin'anjiang Model is applied to discharge modeling. To improve on the evapotranspiration calculation of Xin'anjiang Model, the Aerodynamics resistance method of SSIB which is a land surface model is used to replace the former K-coefficient method, which makes the land surface hydrological model more reasonable. The Shuiyangjiang River Basin in Anhui Province is chosen for the simulation of hydrological studying. The result shows that the improved model performs better than the former model in discharge modeling. |
