在山东胶东半岛母猪河流域构建了分布式水文模型 SWAT,在模型参数敏感性分析、参数率定、模型验证的基础上,对研究区月水文过程进行模拟,并在此基础上分析了母猪河流域近年来水资源时空变化特征.研究结果表明米山水库水文站月径流过程模拟效果较好,率定期和验证期R2和ENS均在0.8左右.母猪河流域多年平均年径流深为372.5 mm,西母猪河源区年均径流深较高,东母猪河子流域较低,流域年径流深基本上呈西高东低的空间分布特征.春夏两季与年径流深空间分布特征较为一致,而秋冬两季径流深空间分布较均匀.汛期7-10月份流域产流量约占全年总产流量84%,极易引发流域性大洪水,而非汛期产流量严重不足,流域水资源短缺问题十分严峻.

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.
