天山山区河流枯季径流消退特性分析

Analysis of the subside feature in dry season runoff in Tianshan mountain area rivers

该文选用发源于天山山区的开都河、黄水沟、清水河和迪那河径流资料,分析枯季径流的基本特征和消退规律,通过分析表明各河流枯水径流的消退均存在一定的规律性,但由于各河流之间流域面积大小、下垫面条件、前期水量的丰枯、冰雪融水以及气象因素不同,各河流枯水期的消退时间、消退历时和消退形式具有不同的特点,同一河流枯水期的不同季节径流消退速度也具有不同的特点。

This article selected file of the Kaidu River, Huangshui Channel, Qingshui River, and Dina River that originated from Tianshan Mountain Area, analyzed the basic feature and subside pattern, through the analysis we found that the subside of every river runoff in dry time has the certain regular pattern, however, because of the size of drainage area, un- derlying condition, the amount of early water storage, snow melting and weather factors are not the same, the subside time, period and form of every river in dry time has different feature, the subside speed of the same river in dry time of different season also has the different feature.
