汾河上游水保治理对汾河水库泥沙淤积的影响分析

分析了汾河上游水土保持治理对汾河水库泥沙淤积的影响。结果表明,随着时间的推移,汾河水库来沙量及淤积量总体呈减少趋势,减少幅度最明显的是在1998年以后。究其原因,除受降水量及入库水量减少因素影响外,主要是上游水土保持治理发挥了重要作用。

Analysis on the Influences of the Treatment of the Water Loss and Soil Erosion in Upper Reaches of Fenhe River on Sedimentation Accumulation of Fenhe Reservoir

This paper makes the analysis on the influences of the treatment of the water loss and soil erosion in upper reaches of Fenhe River.The results show that as time goes,the coming sediment and sediment deposition of Fenhe reservoir tend to a decrease generally,the most obvious decline occurs after 1998.To investigate its reasons,in addition to the influences of the decrease of precipitation and reservoir inflow,the treatment of the water loss and soil erosion in upper reaches of Fenhe River plays an important role.
