由于海岸带地理、地质条件的特殊性,我国重点海岸地下水资源环境承载力脆弱。近年来,围海造陆等海岸工程加快,海岸带环境水文地质问题频发,生态环境恶化,已经严重制约我国海岸带的生态建设。文章分析了我国海岸带环境水文地质特征,研究海岸带地下水需求现状和不合理开采地下水所产生的主要地质环境问题,指出水资源短缺、海(咸)水入侵所导致的生态环境退化问题将严重制约我国海岸带的可持续发展,如何科学促进地下水资源和环境的协调发展,已成为我国海岸带综合管理的一项重要战略任务。
Due to the geography and geological conditions of the coastal zone, the environmental carrying capacity of the groundwater resource of China’s key coasts is fragile. In recent years, coastal engineering such as land reclamation has accelerated, coastal hydro-geological problems have been frequent, and the ecological environment has deteriorated. This has seriously restricted the ecological construction of the coastal zone in China. This paper analyzes the environmental and hydrogeological characteristics of the coastal zone in China, studies the status quo of the groundwater demand in the coastal zone and the major geological and environmental problems caused by the unreasonable exploitation of groundwater. It points out that the problem of ecological environment degradation due to the shortage of water resources and sea and salt water will be serious Restricting the sustainable development of China’s coastal zone and how to scientifically promote the coordinated development of groundwater resources and environment have become an important strategic task for the comprehensive management of China’s coastal zone.
