In this paper, the characteristics and tendency of annual runoff changes of Naolihe River are analyzed, which is regarded as a typical marshy river in Sanjiang plain.
在分析三江平原典型沼泽性河流挠力河径流演变特征及趋势的基础上,应用灰色关联分析和径向基函数网络等方法,探讨了引起径流量减少和发生突变的原因。
This study investigated precipitation and runoff changes and their driving forces of marshy river in the Sanjiang Plain over the second half of the 20th century.
结果表明 :从 2 0世纪 5 0年代至今 ,研究区沼泽性河流的年降水量和年径流量都有减少的总趋势 ;年降水量和年径流量分别在 5 0年代和 6 0年代发生一次突变减少现象 ;近 5 0年来 ,随着宝清水文站和菜嘴子水文站之间的沼泽湿地不断减少 ,沼泽性河流流域的滞洪调节作用也发生明显变化 ,5 0年代后期至 70年代末 ,研究区出现年最大出流量小于入流量年份的频次是 5 0 % ,而 80年代至 90年代 ,其频次只有 35 % ,表明研究区的滞洪调节作用在逐渐减
