兴国县北部地下水补给量估算
|
摘要
地下水是江西省兴国县北部地区居民生活用水的主要来源,在分析研究区自然地理、地质、水文地质特征的基础上,运用降水入渗系数法、地下径流模数法对不同含水岩组及不同地下水系统的地下水补给量进行计算。计算结果表明,地下水补给量与含水层出露面积及降水入渗系数有关,兴国县北部地区地下水天然补给量为1 565万m~3/a。
Groundwater is the main source of living water for residents in the northern area of Xingguo county.On the basis of the analysis of the characteristics of natural geography,geology and hydrogeology in the study area,the groundwater recharge of different aquifer rock groups and different groundwater systems is calculated by the method of precipitation infiltration coefficient and underground runoff modulus.The calculation results show that the groundwater recharge is related to the outflow area of the aquifer and the coefficient of rainfall infiltration,and the water supply is 15 million 650 thousand m~3/a in northern area of Xingguo County.
