| 摘 要： | 以青海湖流域的布哈河为例,采用变差系数、集中度和集中期等指标,对青海湖流域内径流量、降水量在年代、年际、季节等时间尺度上进行分析,并用集中期来反映河川径流对降水的滞后效应。结果显示,河川径流年内主要集中在6—10月,特别是7月中旬至8月中旬之间;降水主要集中在5—9月,特别是7月;径流量与降水量存在极大的相关性（r=0.746＞0.443=α0.001(47)）,径流对降水具有滞后效应,多年平均滞后时间为20 d左右。

| Abstract: | The Buha River is the largest river in Qinghai Lake basin.In this paper,the variations of runoff and precipitation in decadal,annual and seasonal time scales are analyzed based on assessment indices of variation coefficient,concentration frequency and concentration period,also the hysteresis of runoff to precipitation is discussed with the Buha river as an example.Results show that runoff of the Buha River is mainly concentrated in period from June to October,especially from mid July to mid August,and preci... |
