摘　　要：从统计学角度分析深圳市污染物净排放总量与其近岸东、西部水体富营养化之间关系。研究结果表明:深圳市东部海域水体活性磷酸盐、EI值以及西部海域水体中的N:P分别与近岸排污呈现较好的相关性,他们似可作为深圳排污与近岸水体富营养化关系指标。深圳东西部水体由于地理条件、海湾的封闭性的差异,造成东部水体更易受到深圳近岸排污的影响,而西部水体较为开放,受珠江水系、深圳和香港排污等多重因素的影响,因此在研究深圳近岸污染物排放总量与赤潮发生关系时,应选择东部水体作为研究对象。The relationship between the total net discharged amounts of pollutants （TNDAP） and the eutrophication in Shenzhen eastern and western coastal water was analyzed by statistics. The results of analysis revealed that the activated phosphate and EI in eastern coastal water as well as N ： P in western water were positively correlated with TNDAP, respectively. They seemed to be used as indexes that TNDAP impacted on the eutraphication in Shenzhen coastal water. The differences in geographical conditions and the close situation in the bays between eastern and western coast caused, the former was easily influenced by the pollutants from Shenzhen. As for western coastal water, it is much opener and influenced by multi-factors, such as Pearl fiver and pollutants from Shenzhen and Hongkong, Therefore, comparing with the western coastal water, the eastern coastal water is an optimal position where the relationship between TNDAP and red tides occurrence could be studied.
