摘要
在分析地下水水环境容量内涵及地下水资源开发利用产生的环境效应基础上,探讨了地下水环境容量的概念,认为地下水环境容量是用来表征一定目标约束下,地下水系统对自然或人类活动影响所能承受能力的最大阙值,并以上海市为例,采用地下水临界水位、地面沉降量、地下水质作为评价指标对地下水环境容量进行了评价,并将其应用于上海市地面沉降防治工作中,剖析了地下水资源管理和地面沉降控制的工作机制。升,第四承压含水层向弹性变形态势转变,土体表现为微量回弹。
On the basis of analyzing groundwater-environmental capacity and environmental effect by exploiting groundwater resources,the concept of groundwater-environmental capacity is discussed.The discussion holds that roundwater-environmental capacity is maximum value,which the groundwater system bears the effect of natural and human activity in a certain constraint condition.So as a case study of shanghai,groundwater-environmental capacity is analyzed by using evaluation indexes of critical water level,land subsidence and water quality.And its application is used in preventing land subsidence,and the working mechanism of groundwater resources management and land subsidence controlling is analyzed.
