摘    要:20世纪80年代以来,由于流域下垫面条件的改变,山西许多流域的降雨径流规律都发生了重大变化。在同样的年降水量条件下,80年代以后的年径流量显著低于80年代以前的年径流量值。为了保持水文系列的一致性,在工程的规划设计中,须首先修正80年代以前的年径流系列值,随后相应年份的月径流系列也必须修正。文中提出了根据降雨资料相似性对月径流系列进行修正的方法,并给出了一个算例。

关 键 词:降雨~径流关系  径流系列修正  成长曲线  兰氏距离

Abstract:Since 1980's,the relationship of rainfall-runoff in many river basins of Shanxi Province has changed a great deal because of the change of underlying surface of river basin.In the same condition of annual precipitation,the annual runoff since 1980's are outstandingly less than before 1980's.In order to preserve the consistency of hydrological series,the monthly flow time series must be modified after modifying the annual flow time series in the process of project planning and design.This paper presents a method of monthly flow modification and a case study according to the similarity of precipitation.
Keywords:rainfall-runoff relationship modification of flow time series Logistic Curve Lance and Williams distance
