通过对雷州半岛逐日的降水量和地下水位进行连续测量,分析研究了该区地下水位动态的变化规律,结果表明:(1)雷州半岛地下水位存在年周期的变化规律,水位上升期大约在6～10月的雨季,其余时间为水位下降期;(2)在地下水补给区,地下水位上升期间地下水位累积增幅与逐旬累积雨量有明显的正相关关系;在水位下降期,地下水位的下降速度与地下水位也呈正相关关系;(3)在目前的开采条件下,丰水年的降雨对地下水资源进行有效的补给和恢复。
The daily variation of groundwater level in Leizhou peninsula was measured and analyzed continuously. The results showed that: (1) The annual variation of groundwater level in Leizhou peninsula was about 6 (2) In the groundwater recharge area, the cumulative increase of groundwater level during the rise of groundwater table has a significant positive correlation with the accumulated rainfall over the period of ten days. During the decline period of the water table, the groundwater table declines There is also a positive correlation between speed and groundwater level. (3) Under the current mining conditions, rainy days can effectively replenish and recover groundwater resources.
