摘要
选取南水北调西线一期工程下游的朱倭、朱巴、绰斯甲和足木足4个水文站(1960-1996年)的径流资料及其同期的降水、气温等数据,采用灰色关联分析方法,对调水河流的径流补给来源进行了初步分析,结果表明:4站的径流均与年降水量或4～6月降水量的关联度最高,说明径流的补给来源主要是降雨量,这一初步分析结果为长江上游水资源的可持续开发利用提供了较为科学的依据。
Based on the data of runoff and precipitation and air temperature in Zhuw~ Hydro-station and Zhuba Hydro-station and Chuosijia Hydro-station and Zumuzu Hydro-station on the first stage Project of the South- North Water Transfer Scheme via the Western Route,the runoff supply source is primarily analyzed by gray relation analysis method.The result shows that the relation grade between runoff and annual precipitation or 4-6 month precipitation is best,which shows that the main source of runoff is precipitation.The analysis result provides scientific gist for planners to sustainably utilize water resource of upper reach of Yangtze.
