| 摘 要： | 利用1961~2000年汉江流域15个测站的月径流量、月降水量和月平均气温资料,分析了水文序列的正态分布性和非正态序列的正态化,采用里和海哈林法等分析了流域径流、降水和气温的变异性。结果表明,在汛期时,汉江流域降水和径流的变点年份基本一致;枯水期时,变点年份不一致。主要原因是丹江口水库的调节作用,对汉江中下游径流量的影响枯水期远远大于汛期。而气温与径流的变点年份相差较大,表明汉江径流量变异的主要因素不是气温,主要受降水和水库调节的影响。

| Abstract: | Using data of monthly runoff,precipitation and temperature from 1961 to 2000 at 15 stations in the Hanjiang River basin,normal statistic distributing of hydrological time series were calculated,and were normal transformed if they were not normal statistic distributing.Change-points of monthly runoff,precipitation and temperature were analysis by Lee-Heghinan methods,etc.The results showed that change-points of precipitation and runoff in the Hanjiang river basin were the same in the flood period and the dif... |
