摘要
为防止和控制地面沉降,增加地下水资源量,拟以典型试验场地为例开展地下水人工回灌试验。为保障区内地下水环境质量安全,节省回灌成本,本次采用基于熵权的模糊综合评价法对区内不同回灌水源进行优选。评价结果表明,备选水源B为最优回灌水源,回灌成本最低为2.269元/m3。该评价结论可为研究区全面开展地下水人工回灌工程提供一定的技术支持。
Groundwater artificial recharge was conducted as an efficient measure that could prevent or control land subsidence,as well as increasing groundwater resources. In order to protect groundwater quality and save the project cost,Entropy weight Fuzzy Comprehensive Evaluation Method was used to determine the optimal water. Evaluation results show that Water of River B is the optimal recharge water with the lowest recharge cost about RMB2.269/m3. The optimal water management decisions provide technical support for the city to carry out overall groundwater artificial recharge engineering in deep aquifer.
