摘要
本文对给水度概念及变化机理进行了系统的论述 ,并通过实例论证了给水度的变化特征。结果表明 :给水度不仅随抽水历时的增加而增加 ,同时也受地下水埋深、非饱和带岩性、气压、水质。
Concept of specific yield and variations mechanism in were discussed system atically the paper. Demonstrating changing features of specific yield through example. The results show that: specific yield of aquifer increase with pumping time extending, but also be influenced by underwater depth, rock feature of unsaturated belt, atmospheric pressure and temperature.
