宁波市蛇蟠岛应急水源地建设与环境效应

Research of emergency water source area construction and environmental effect evaluation for Shepan Island of Ningbo City

在评价宁波市蛇蟠岛淡水资源量的基础上,估算其应急供水规模。通过构建地下水数值模型,预测在应急开采条件下地下水位恢复能力,并对应急开采产生的地下水降落漏斗、地面沉降和咸水入侵等环境效应进行了评价。结果表明,蛇蟠岛地下淡水具有应急水源地建设可行性,为该地区进一步勘查应急水源地提供了依据。

In this study,the emergency water supply capacity of the Shepan Island in Ningbo City was estimated based on comprehensive evaluation of the freshwater resources on this island. A groundwater numerical model was established to predict the groundwater level recovery capabilities in emergency exploitation conditions. In addition, the environmental effects such as groundwater depression cones, land subsidence, and saltwater intrusion were evaluated. The results show that it is feasible to construct the emergency water source area on the Shepan Island. This study provides a basis for further exploration of emergency water sources in the area.
