摘要
根据2007年8月大沽沙航道水域浮游植物的调查资料及水质监测数据,研究了该水域浮游植物的分布特征及富营养化状态。综合单因子生物法和营养指数法的评价结果表明,该水域污染较严重,尤其是靠近大沽排污口的水域已经严重富营养化,排污河向航道输入大量含有N、P营养盐的污染物,造成水质污染。今后应严格控制大沽排污河污染物排放总量,减少陆源污染,有效防治"赤潮"的发生。
Based on the surveyed data of phytoplankton and water quality in the water area of Dagusha Channel in Aug. , 2007, the distribution characteristic of phytoplankton and the eutrophication level in the water area were analyzed. Considering the integrated evaluation resuits of biological assessment and trophic state index, it showed that the water pollution was very serious; especially the water near Dagu sewage drainage outlets was badly eutrophication. The nutrient pollutants characterized by considerable amount of N and P were carried from the sewage drainage outlets, which caused water pollution. In the future, total pollution discharge should be strictly controlled and the pollutant discharged from land to sea should be reduced in order to effectively prevent the occurrence of red tide.
