摘　　要：利用澜沧江干流允景洪水文站1956～2008年的月径流系列数据,分析了澜沧江干流水电开发对下游径流的影响。结果表明:澜沧江干流已建大坝对其下游干流径流有明显的调节作用,主要影响年内月径流分配,表现为削弱了雨季洪水流量,提高了旱季径流量。Based on the monthly runoff data series from 1956 to 2008 obtained from Yunjinghong Hydrological Station on the main stream of Lancangiang River,the impacts from hydropower development of main stream on runoff of Lancangjiang River are analyzed herein;from which the results show that the built dams play obvious roles in regulation of the runoff of the downstream of the river with the major influence on the distribution of the monthly runoff,i.e.decreasing the flood discharge during rainy season and then increasing the runoff flow during the dry season.
