摘要
根据 1 994～ 1 998年 5a对象山港平、丰二期水质监测资料 ,以DIN、DIP、COD和DO作为化学指标参数 ,分析了该港湾有机质污染和营养类型。并从各个监测时段、监测频次、监测站位、监测层次分析了水质变化趋势 ,同时对陆源排污和水生浮游植物进行了相关分析。综合分析结果表明 :象山港水质明显呈高N低P状态 ,水质基本上属于中度污染 ,且整个港湾水质处于严重富营养化状态。其平、丰期水质主要与陆源排污和海洋浮游植物光合作用有关。
Based on the monitoring data from 1994 to 1998 at Xiangshan Port, the types of organic pollutants and nutrition were analyzed in terms of DIN, DIP, COD and DO, as well as water quality changing trend with the monitoring time, frequency, station and layer. Finally, correlation of the pollution sources and aquatic drifting plants was discussed here. The result shown that the water at Xiangshan Port was polluted by high N and Low P pollutant. The pollution level was moderate but water quality was seriously overnourishous. The pollution sources is mainly from the waste discharges of the land and photosynthesis of aquatic drifting plants.
