论广花平原隐伏岩溶水资源的补给条件

广花平原隐伏岩溶水接受垂向的间接补给,侧向补给很弱;越流补给面积大于渗流补给面积;雨后井水位即时上升,多数属压力传递而不是获得水量补给;开采井给水能力较大而补给常跟不上,补给条件不是原先估算的那样好。釆区静水位下降的主要原因是过量开采,井干扰属次要因素。由隐伏岩溶中未完全淡化的海水残留,说明用达西模型计算岩溶水径流量是可行的。

Discussing the Recharge Condition on Covered Karstic Water Resource in Guanghua Plain

The covered karstic water in Guang-Hua Plain receives vertical indirect rec-harge,the lateral recharge is very weak.The area of the leakage supplementation exceeds that of the seepage.The cause of the well-water level rises at once after rainfall is mostly not that karstic water obtains supply,but that pressure transm-its.The Capacity of water supply of the exploited wells are often larger than the complement.The recharge condition is not utterly well as former evaluated.The main cause of the static water level drops in the exploited districts is the overex-traction and the well interference is secondary.According to the remains of sea water which is not completely desalted,it is shown that using Darcy model to count karstic water runoff is feasible.
