中文摘要:

      未来地下水资源短缺,特别是由于地面沉降、地表退化、海平面上升等引起的地下水位下降,将对沿海地区的地质环境及人类的生存发展产生极大的影响。通过对崇明地区地下水资源利用现状以及影响地下水位下降的影响因素分析,提出了改善传统的灌溉系统来减少地下水资源的使用、海岸沿线修建人工湖泊防止海水入侵、鼓励农民大面积种植水稻、制定管理措施严格控制地下水的开采总量、进一步加强崇明岛地面沉降动态监测与研究等相应的防范措施。强调控制地下水位的下降,以减轻淡水资源短缺所造成的危害,具有特殊而重要的意义。

英文摘要:

      Future groundwater resources shortage, especially the underground water level decreasing caused by land subsidence, surface degradation and sea levels rising, will have a great impact on coastal environment and human survival and development. Based on the analysis of the current groundwater resources in Chongming area and the influenced factors of groundwater level decline, the corresponding prevention measures were put forward, such as improve traditional irrigation system, construct lakes close to the coast to avoid seawater instrusion, growing rice, strict control of groundwater exploitation amount, strengthen the dynamic monitoring of land subsidence and the corresponding prevention measures. So how to control the decline in groundwater level control and alleviate the shortage of water resource has a special and important significance.
