摘　　要：以辽河干流、浑河、太子河3个子流域为研究区域,依据地域代表性选取辽河干流石佛寺水文站、浑河沈阳水文站、太子河辽阳水文站为分析测站,依据各测站1956-2000年月径流资料,分析辽河流域径流年内、年际变化规律。结果表明:辽河流域径流年内分配极不均匀,月径流变化幅度比较大,其中辽河干流最大月径流可占年总径流的60%以上;径流年际变化趋势不显著,约存在10 a、12 a、19 a、21 a的周期。Taking the Liaohe River,Hunhe watershed and Taizihe watershed as research districts,and taking Shifosi Station on Liaohe River,Shenyang Station on Hunhe watershed and Liaoyang Station on Taizihe watershed as analysis stations according to district representation,the characteristics of annual and yearly variation of runoff series in the Liaohe Basin are analyzed.The runoff series is from 1956 to 2000.The results show that annual runoff distribution is non-uniform and monthly runoff variation is serious,among the three research districts,the max month runoff in the Liaohe River may contain 60 percent of yearly runoff.The yearly variation trend is no significance,the variation trend is about 10 years,12 years,19 years and 21 years.
