| 摘 要： | 地下水位的变化具有周期性的特点，在本地区与降水关系比较密切。通过资料分析可以看出地下水位变化趋势与各月降水量的变化趋势基本一致。年度各月平均地下水位变化曲线图整体形状呈山谷状，大体上水位下降时间相对较长，高水位保持时间较短。年度各月水位的变化紧随降水的变化，降水量大，水位则高，反之则低。降水对地下水的补给具有滞后的同步性，时间大体上在2个月左右。年降水量出现丰桔变化时，地下水位也随之产生高低变化，因此，降水与水位变化关系密切。

| Abstract: | There is the seasonal characters among groundwater level changes which is close relation between the local area and its precipitation. The article is based on data analysis and found out which is almost similar of the changing trend of the groundwater level and monthly precipitation. The changing curve of the monthly average groundwater level looks like the hollow for a year. The groundwater level basically takes longer time to drop and the higher level keeps short time. The level is higher following the precipitation. There is later synchronization of precipitation recharging to the groundwater and it requires about 2 month. If the precipitation is dried up, the groundwater level will also changed, so there is close relation between precipitation and level changes. |
