| 摘 要： | 以黄河三角洲地区徒骇河流域为例,采用集中度、集中期等方法对徒骇河流域1970年代以来径流、降水特征及其变化进行了分析.结果表明,徒骇河流域河川径流量年内主要集中在6～10月,集中期主要在7月下旬至8月上旬;降水主要集中在6～9月,集中期主要在7月中旬和下旬;径流对降水具有滞后效应,多年平均滞后时间约为11.1d.

| Abstract: | Based on the methods of concentration frequency and concentration period,this paper discusses the characteristics and change of runoff and precipitation since the 1970s of the Tuhai River Basin.The results show that the runoff of the Tuhai River mainly concentrates in June to October,especially in late July to early August.While the precipitation mainly concentrates in June to September,especially in mid and late July,there is a hysteresis of runoff to precipitation,and the average hysteresis period is about 11.1 days. |
