| 摘 要： | 基于空间半分布式的SWAT模型和全分布式的WetSpa Extension模型,分析了高分辨率的SoLIM数字土壤数据和美国SSURGO传统土壤数据对流域径流空间分布式模拟和总量模拟的影响.结果显示:利用不同土壤数据得到的产水模拟结果在空间上差别明显,但模拟径流总量的差别随着模拟面积的增大而逐渐减小.根据实验结果,对于...

| Abstract: | Effects of different soil data resolutions on distributed hydrological modeling and total water yield were investigated using a modeling approach.The semi-distributed SWAT(Soil and Water Assessment Tool) model and the fully distributed WetSpa(Water and Energy Transfer between Soil,Plant and Atmosphere) Extension were used in this study.Both the US SSURGO(Soil Survey Geographic) soil data and the detailed SoLIM(Soil-land Inference Model) soil data were utilized in the modeling investigation.Results show that... |
