为分析人类活动对浑河径流特性的影响, 利用浑河流域的北口前、大伙房、抚顺、沈阳、黄腊坨和邢家窝棚6 个 水文站1959 年22011 年的日流量资料, 以大伙房水库关闸蓄水时间为初始研究时段, 对比分析了研究时段内浑河流 域年、汛期、非汛期、月及日径流量的变化特性。结果表明: 大伙房水库建成后的前20 年, 浑河流域径流量变化平 缓, 而之后的近30 年里径流量出现偏高峰值, 但是大伙房水库汛期蓄水量所占比例并没有显著变化, 汛期蓄水量变 化趋势与全年蓄水量变化趋势十分相符。

In or der t o analy ze the impact o f human activ ities on the runoff char acter istics of Hun River Basin, the daily runo ff da2 ta o f six hy dr olog ical stations, including Beikouqian, Dahuo fang , Fushun, Shenyang, H uanglatuo, and Xing jiawo peng, fr om 1959 to 2011 w ere selected, the t ime when Dahuo fang reservo ir w as closed and started to st orag e water w as selected as the initial re2 search perio d, the variatio n character istics o f annual runo ff, r unoff in the floo d seaso n and non2floo d season, monthly runo ff, and daily runo ff wer e compared and analyzed. The r esults show ed that runo ff in the Hun River Basin has slig ht v ariat ion in the fir st 20 years after the com pletion of the Dahuofang r eser vo ir, and hig h peak of r unoff appear s in the subsequent 30 year s.
