摘要

利用汾河水库1956-2004年入库径流和降雨量资料

在采用统计学方法探讨径流和降雨变异分析的基础上

建立双累积曲线模型

分离出了降水变化和水土保持措施分别引起的径流变化量

在定义贡献率的基础上

分析水土保持措施和气候变化对径流演变的贡献。结果表明

1956-2004年49年来汾河水库入库径流和降雨均呈减少的趋势

但径流减少趋势明显;以入库径流突变年份为界将研究时段分为2段(1956-1982年和1983-2004年);水土保持措施的实施致使径流减少24.8mm

贡献率为87.1%

降雨减少致使入库径流减少3.7mm

贡献率为12.9%。流域内从20世纪80年代初开始的水土保持措施实施改变了水库上游流域的水文循环过程。

Abstract

This study separated the effects of climate change and soil and water conservation on reservoir inflow in the Fenhe reservoir using runoff and precipitation data during 1956-2004 by building double mass curve model based on using statistical methods.Contribution of soil and water conservation and climate change to runoff variation were analyzed based on defining the conception of contribution rate.The results showed that reservoir inflow and precipitation tended to become lower for the period

but reservoir ...
