三都湾水产养殖区表层水环境污染及发展趋势研究

Studies on the Aquatic Environment Pollution and Variation Trends of Surface Layer at the Aquaculture Region,Sangdu Bay

本文根据2002年福建三都湾水质监测数据,对照2000年监测资料,采用富营养化指数和有机污染指数模式,对该湾水产养殖区表层水环境的污染状况和变化趋势进行了分析研究。结果表明,目前湾内的主要污染物为无机氮和活性磷酸盐,且二者浓度近年来均有上升的趋势;从平面分布上看,呈湾顶区大于湾口区的特点,局部富营养化明显,有机污染指数也有上升的趋势。同时对调查结果提出了相应的环境保护对策。

Based on the water quality monitoring data in Sandu Bay of Fujian in 2002 and compared with the monitoring data in 2000,this paper studies the aquatic environment pollution and variation trends of surface layer at the aquiculture region of Sangdu Bay by analysising the nutrient status index and organic pollution index.The study shows that the major pollutants of the Bay are inorganic nitrogen and active phosphates,and in recent years their concentrations have upward trends;From plane distribution,the concentration of the top Bay Area is higher than that of the Bay Estuary,eutrophication appears in local waters,and organic pollution index has an upward trend.At the same time,this paper provides the corresponding environmental protection countermeasures.
