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。
From the statistical point of view, this paper analyzes the relationship between the total net pollutant emissions in China and the eutrophication of water bodies in the east and west coasts of China. The results show that the active phosphate, EI and the N: P in the water bodies in the eastern part of Shenzhen City show a good correlation with the near-shore discharge, respectively. They may serve as the eutrophication relationship between the coastal and offshore waters in Shenzhen index. Due to the differences in geographical conditions and the closure of the bay, the water bodies in the eastern and western parts of Shenzhen caused the water bodies in the east to be more susceptible to the coastal discharge of Shenzhen. However, due to the openness of the water body in the western part of the country, due to multiple factors such as Pearl River, Shenzhen and Hong Kong, When the total amount of near-shore pollutant emissions in Shenzhen is related to the red tide, the eastern water should be selected as the research object.
