摘　　要：根据启东近岸海域2003—2009年7个站点的监测数据,研究了该海域的水质营养状况,并初步分析了与相邻陆域农村水环境质量的关系。结果表明:除平台站点之外,多数站点的COD、DIN、DIP和DO有增加的趋势;仅平台站点在2003年未富营养化,其他6站点都处于富营养状态,在2007年富营养化指数达到最高值,其后逐年显著降低;2003—2009年重污染海域比例达到4.1%,在2007和2008年是污染较为严重的年份;富营养化指数与综合标准指数之间存在显著的正线性相关;相对于城市工业生产生活排放,启东近岸陆域农村水环境质量变化和长江径流对近岸水质营养状况的影响较小。Based on the 2003-2009 monitoring data from seven stations in the nearshore water area of Qidong, this paper analyzed the eutrophication status of this water area and its relations to the water environmental quality of adjacent rural areas. At the stations except Pingta , there was an increasing trend in the water COD, DIN, DIP, and DO. The waters at all the stations, except at Pingtai in 2003, were in eutrophication. The nutrient status index reached the highest value in 2007, and kept dropping down after then. In the study period, the seriously polluted water area occupied 4.1% of the total, and the water quality was the worst in 2007 and 2008. The eutrophi- cation index had a significant positive correlation with the comprehensive standard index. Rela- tive to the discharge of urban industrial waste water and domestic sewage, the water environmen- tal quality of adjacent rural areas as well as the runoff of Changjiang River had minor influence on the nutrient status of Qidong nearshore water area.
