Groundwater level can be recovered by artificial regulation of water resource in the empty underground space of the depression cone.
利用降落漏斗区腾空的地下储水空间进行水资源的人工调蓄可使地下水位得到恢复。
Then not only the problem of queer dot at the well bore is avoided, but also the radius of influence domain (R) of the depression cone is convenient to deduce.
利用基于流量的相似方法分析了井流场中的渗透情况，此方法以流量作为未知函数，不仅避开了井口奇点问题，而且还可根据实际情况方便地推导出降落漏斗的影响区域半径（影响半径R）。
Large quantity of continuously groundwater pumping in an area forms regional groundwater depression cone, and overexploitation leads to a series of environmental and geological problems.
对地下水资源的长期大量集中开采形成了区域性地下水位降落漏斗，地下水的超采引发了一系列环境地质问题。
