春、夏季降水对水库蓄水量的影响

Analysis of Influence on Reservoir Water Capacity by Rain in Spring and Summer

在分析贵州两大水库控制流域气候状况和蓄水特征的基础上 ,进行春、夏季降水对水库蓄水量的影响分析 ,指出 :春末、夏末水位均与流域内前两个月的降雨量相关最好 ;当红枫湖、乌江渡控制流域 4～ 5月降雨量分别达到 5 5 0 mm、40 0 mm时 ,相应水库的春末蓄水位将达到正常蓄水位 ;当红枫湖、乌江渡控制流域 7～ 8月降雨量分别达到 780 mm、5 0 0 mm时 。

The influence of rainfall in spring and summer on reservoir water capacity was analyzed on basis of analysis of the climatic conditions of two large reservoir′s control valley and the water storage character.The best correlation between the rain in the valley and the water level in late spring and late summer was put forward.When the rainfall in April and May reach 550mm and 400mm,the water level of Hongfenghu and Wujingdu in late spring and May will reach the normal high level respectively,and when the rainfall reach 780mm and 500mm in July and August,the water level in late summer also reach the normal level.
