国内外地下水入海通量研究现状与趋势

A review of submarine groundwater discharge home and abroad

地下水向海排泄是海陆相互作用的重要过程,它可能是陆地污染物质和营养盐排放入海的重要通道,会对近岸的海域环境产生一定的影响。它已在国外受到相当多的重视,而我国的相关研究还很少见。文中介绍了该领域的三种主要方法:原位测量方法、模型技术和示踪技术,且探讨了其发展方向及趋势。

Submarine groundwater discharge （SGD） is an important part of interactions between land and sea. It may serves as a pathway for land nutrients and pollutants to the coastal ocean and can exert some influences on the coastal environment. It has attracted more and more attention abroad, but it is seldom examined in China. In this paper, three basic approaches to the SGD flux, including direct measurements, modeling and tracer techniques, and their tendency are also presented in detail.
