【摘要】 基于深圳某中心区核心地块地下水资源评价的成果分析 ,探讨了影响地下水储量及长期抽取地下水对环境影响的若干因素 ,强调了抽水试验井的成井工艺和洗井工艺及长期沉降观测在地下水资源评价中的重要性 ,提出了在水位降深不变的情况下 ,抽水井的涌水量随时间有缓慢减少趋势的观点以供探讨。更多还原

【Abstract】 Based on the result analysis on the groundwater resource evaluation at the core plot of the central area in Shenzhen,factors to influence the groundwater reserv es and the environment owing to water pumping for a long time are discussed.The importance of the well\|drilling craft and well\|washing craft for the testing w ells and the long\|time subsidence observation in groundwater resource evaluatio n is emphasized.It is pointed out that the outflow rate in pumping wells would s lowly reduce with time under the condition of constant water level.更多还原
