Attribution analysis of changes in runoff in the upstream of the Miyun Reservoir
摘要
Abstract
Studying the trends and laws of runoff is fundamental to the proper use of water resources.The Miyun Reservoir is the only surface water source in Beijing and is important to Beijing's water supply.In September 2015,water from SouthNorth Water Diversion Project (SNWDP) was added to the reservoir.Therefore,studying the runoff of upstream in Miyun Reservoir is more necessary for the proper management of the reservoir than ever before.As the amount of the water from SNWDP should supplement the runoff of the upstream,to know the trend of the upstream is necessary.Accordingly,the study analyzed the multi-temporal scale changes and abrupt change of the runoff,the influence factors of the runoff of Zhang Jiafen and Xiahui stations from 1960 to 2014.The methods of trend analysis,the moving average method,the Mann-Kendall method,wavelet analysis,the flow duration curve,and the double mass curve were used.The results indicated that the runoff in Miyun Basin mainly concentrated in July to September,accounting for 70％ of the annual runoff,and runoff in the Baihe Basin changed more significantly than that of the Chaohe Basin.From 1960 to 2014,the amount of runoff slowly decreased at the rate of 3.24 and 1.60m3 s-1(10 a)-i in Baihe and Chahe respectively,and the runoff in Baihe and Chaohe Basin both showed change period of 7a.The results of double mass analysis indicated that the reduction of runoff in Miyun Basin can mainly be attributed to human activities (71.36-91.39％),and the Baihe Basin was disturbed much greater by human activities.关键词
