海底地下水排泄是全球水循环的重要组成部分,是近岸、滩涂和河口地区典型而重要的海水—地下水相互作用过程。作为全球水循环的重要组成部分,海底地下水排泄是海洋中水和各种化学物质的重要来源之一,同时也是各种污染物从陆地向海洋输送的一个重要而隐蔽的通道。综述了海底地下水排泄(SGD)的研究现状与进展,对海底地下水排泄的过程、研究方法、研究分布以及环境意义等方面进行了详细介绍,指出了目前研究存在的不足和需要努力的方向,从而为我国开展大规模海底地下水排泄研究提供了一定的思路。
Seabed groundwater drainage is an important part of the global water cycle and is a typical and important seawater-groundwater interaction process in nearshore, tidal flats and estuaries. As an important part of the global water cycle, seabed groundwater drainage is one of the important sources of water and various chemical substances in the oceans. It is also an important and covert channel for transport of various pollutants from land to sea. This paper summarizes the research status and progress of seabed groundwater excretion (SGD), introduces the process, research methods, research distribution and environmental significance of groundwater discharge in the seabed, and points out the shortcomings of present research and the direction of efforts Provided a certain train of thought for carrying out large-scale seabed groundwater drainage research in our country.
