艾比湖入湖水量与河川径流集中度和集中期的关系

ON THE RELATION OF DISCHARGE FLOW INTO EBINUR LAKE WITH THE ABOUNDANT DEGREE AND PERIOD OF RIVERS FLOWS

径流的年内分配对工农业用水关系密切,对进入艾比湖水量的多寡和水域面积的大小影响很大.过去,一般用各月或四季平均径流量占全年径流总量的百分数来表示河川径流年内的分配的表示方法。但这个方法已不能满足各方面的需要。北京地理研究所汤奇成及长江流域规划办杨远东等人提出用集中度(Cn)和集中期(D)来表示径流年内分配的方法。笔者认为更能准确表示河川上、中。

The waters of Ebinur Lake come from Jing river and Bortala River. The flood periodof Jing River concentrated in summer, and a part of flood flowed into Ebinur Lake becauseof the lower capacity of draw-off the river flows.The flood of Bortala river in summer wereregulated by three underground reservoirs along Bortala river valley, hence the abundantperiod or river flow delayed to winter, and a large amount of winter discharge flowed intoEbinur lake.
