冲积平原水源地资源量计算

Estimation of ground water resources in exploration of water source fields in alluvial plain

水源地资源量计算在水源地勘察中非常重要。本文结合河南省永城市新城水厂小李庄水源地的地下水资源量计算实践,系统地阐述了冲积平原水源地地下水资源量计算的内容及要求。其中,地下水补给量包括大气降水入渗补给量和农业井灌回渗补给量。地下水排泄量包括地下水的蒸发量、开采量、侧向径流排泄量和地表水侧渗排泄量。

Estimation of water resources is very important in the exploration of water source field. Base on estimation of the ground water resources of Xiao Li-zhuang water source field in new municipal area of Yongcheng, Henan province, the content and requirement of calculating the groundwater resources for the water source field of the alluvial plain are systematically expounded in this paper. Recharge of ground water includes infiltration of precipitation water and well irrigation. Groundwater excretion includes evaporation, pumping, lateral runoff, and lateral infiltration of surface water.
