摘要:
对黄河河源区多年平均和雨季降水量、年际径流量进行分析。流域西北部玛多站多年平均降水量变化不大，而流域东南部降水丰沛的久治站则呈现大幅下降的趋势，这对黄河河源区的产流量带来不利的影响。年内降水量以雨季变化较大，且表现出下降的趋势。计算得到径流量的变差系数、年际变化绝对比率和不均匀系数，表明径流量年际波动较大。认为降水强度和降水量是影响黄河河源区径流系数变化的主要原因。
Abstract:
The annual average and rain season precipitation and yearly runoff of the source regions of the Yellow River were analyzed. Annual average precipitation of Maduo station that locates in the northwest of the regions changes with small extend, but annual average precipitation of Jiuzhi station that locates in the southeast of the regions of rich precipitation shows a greatly decreasing tendency, which brings adverse impact on the runoff yield of the source regions of the Yellow River. Intra-annual precipitation changes relatively greatly in rain season and shows a decreasing trend. Taking into account of inter-annual variation of yearly runoff, the authors computed the variation coefficient, absolute inter-annual change rate and non-uniformity coefficient of runoff, and illustrated that the annual average runoff fluctuates relatively greatly. Finally, it is pointed out that rainfall intensity and rainfall volume are the main reasons for runoff coefficient changes.
