伊春河流域径流特征分析

以实例数据为依据,从探讨流域降雨和径流的年内、年际变化规律入手,利用样本数据的均值、极值、Cv值和出现频率等统计参数,对伊春河流域径流的成因及变化规律进行了分析研究。分析结果得出了流域径流年内分配主要集中在夏季,全年各季径流相差悬殊,流域径流年际分配相差较小,径流量年际补给较充足的结论,针对分析结果对提高流域水资源利用效率提出了建议。

Analysis of Runoff Characteristic about Yichun River Basin

Based on observed data, proceeding with river basin rainfall and the changing law of the annual runoff, the statistic parameters of mean value sample data, limited value, Cv value and frequency of occurrence, the runoff genesis and changing law of the Yichun River basin are analyzed and researched. The analyzed results show that the annual distribution of river basin runoff concentrates mainly in the summer, runoff at different seasons differs largely during the whole year, the annual distribution of river basin runoff differs a little, and annual runoff supplement is plenty. Suggestions are put forward for increasing the use efficiency of water resources according to the analyzed results.
