摘要
混合区的确定是水体环境容量计算的核心内容之一,成为水环境研究的重点。我国规定了海洋和河口的允许混合区范围,但尚未出台河流中混合区的相关规定,致使地表水环境容量计算结果经常引发争议。从混合区含义、物理过程、管理要求、研究方法等几方面介绍了国内外水体混合区研究的主要进展情况,并讨论了当前混合区研究中存在的一些问题和发展趋势。
As one of the core contents of water environment capacity calculation,the mixing zone becomes the focus of water environment research. Relevant provisions on the scale of mixing zone of estuarine and marine have been issued in China,but regulations on the river mixing zone are yet to be formulated,resulting in the controversial results of surface water environmental capacity calculation. This paper introduces the research progress on river mixing zone at home and abroad,and discusses the problems and trends in terms of its definition,physical process,management requirements and methodology.
