于桥水库入库水量变化趋势分析

Trend analysis of Yuqiao Reservoir inflow

对于桥水库多年入库水量进行分析计算,得出入库水量有减少的趋势,从流域降水量、用水量及下垫面条件的变化3个方面进行入库水量减少的原因分析,得出入库水量减少的影响程度。最后,为如何增加入库水量提出了合理化建议。

The annual Yuqiao reservoir inflow was analyzed using hydrologic data from many years. The results show that the annual inflow to Yuqiao Reservoir has tended to decrease. The reasons for the decreasing annual inflow to Yuqiao Reservoir were analyzed in terms of the watershed precipitation, water consumption and underlying conditions, and the degree of reduction of reservoir inflow was measured. Finally, this paper provides some rational suggestions for increasing the reservoir inflow.
