摘　　要：系统研究了40多年来海水富营养化指数E定义的发展,进而整理了近10 a来应用富营养指数法评价中国近岸海域水质状态的富营养化指数E值,计算了我国Ⅰ、Ⅱ、Ⅲ和Ⅳ类海水水质标准所对应的E的最大临界值分别为：1.3、6、10.7和25;并阐明了河口近岸海域环境中海水产生富营养化E高值的原因。结果显示,中国近岸海域富营养化指数E值的范围在0～137.84;中国近岸海域出现E的高值不仅与港口海湾所处的自然地理环境有关,也与人为因素有关;人为排放的氮磷营养盐是导致海水富营养化的主要因素。This study illustrated the development of eutrophication index over the past four decadesand and collected the application methods about judging eutrophication in China coastal waters in the last 10 years,by calculating the water quality standards of country Ⅰ,Ⅱ,Ⅲ and Ⅳ class water,we found that E maximum threshold were 1. 3,6,10. 7 and 25,respectively; and the reasons of E high values for offshore environmental estuary seawater. The results show that China＇s coastal waters the values of eutrophication index range was from 0. 00 to 137. 84; High values of E were not only related to the natural geographical environment of port Bays,but also related to human factors; anthropogenic emissions nutrients of nitrogen and phosphorus were the main factors to cause the seawater pollution.
