| 摘 要： | 分布式水文模型PRMS可为气候与土地利用变化对流域水资源影响的研究提供技术和理论支撑.对Trent流域产流过程采用PRMS模型进行模拟检验,结果表明,Nash模型确定性系数达到0.8以上.水文响应单元(HRU)划分尺度减小,可以有效地提高PRMS模拟精度达7%左右,划分尺度缩小到71个HRU时,模拟精度不再提高.流域蒸...

| Abstract: | The distributed precipitation-runoff modeling system(PRMS) will support the study on the impacts of climate change and land-use change on water resources in a watershed.Modeling results show that the PRMS model performs satisfactorily for simulating water yield,as indicated by an overall Nash-Sutcliffe simulation efficiency over 0.8.The reduced scales of HRU(Hydrological Response Units) delineation show a better model-fit efficiency to some extend about 7%.The 71 HRUs delineation can result in the best over... |
