在干旱的河谷港水地区建设水源地,往往由于枯水季节地下水的补给不足,而采取将含水层逐步疏干,待翌年丰水季节补充恢复的办法来解决水源地的连续供水问题。水源地的疏于性开采,要求含水层具有相当的贮水和调节条件,並通过水源地的干扰降深计算与丰水期可否补偿的验证,来判断开采程度及其合理性,进而确定水源地的允许
The construction of water sources in the dry river valleys and valleys often results in the problem of continuous water supply in the water area due to insufficient supply of groundwater in the dry season and the gradual dewatering of aquifers to be supplemented and resumed in the abundant water season the following year. Inconvenient exploitation of water sources requires that aquifers have considerable water storage and conditioning conditions, and the degree of exploitation and its rationality should be determined through the calculation of the interference reduction of water sources and the verification of compensability during the wet season, so as to determine the water source Earth’s permission
