基于S WA T模型的母猪河流域水资源时空变化特征研究
Spatiotemporal variation of available water resources in the Muzhu River basin
摘要
Abstract
A distributed hydrological model was developed with SWAT (Soil and Water Assessment Tool) in order to analyze spatiotemporal variations of available water resources in the Muzhu River basin,Jiaodong Peninsula,in Shandong Province.Analysis of parameter sensitivity,calibration and validation were performed to simulate monthly hydrograph.The simulation performance of monthly hydrograph at Mishan Reservoir hydrological station was quite satisfactory.Calibration and validation period R2 and ENS were both around 0.8. Averaged annual runoff depth was 372.5 mm,the source area of the West Muzhu River contributed to high runoff depth,while the East Muzhu River had relatively little contribution.Averaged annual runoff depth in the Muzhu River basin exhibited spatiotemporal variations:high in the west,low in the east.Spatiotemporal variation in spring and summer runoff depth was consistent with annual runoff,while autumn and winter runoff depth was uniformly distributed.Water yield in flood season (July to October)in the Muzhu River basin accounted for about 84% of annual water yield.Basin-wide large floods were common,but water yield during non-flood season was seriously insufficient,which would sharply worsen water shortage.关键词
