深圳市社会经济发展与近岸水体富营养化关系研究(Ⅰ)

通过对深圳市近年来近海海域水体水质数据分析,研究和评价该海域水质演变趋势,并对这种趋势进行环境经济原因分析。得出以下结论:1.西部海域水体富营养化程度比较严重;2.深圳东、西部海域近年N:P值都远远超过16,属于严重的P缺乏型海域;3.深圳海域的大部分水质指标在1998年以后都有大幅上升的趋势,反映了深圳市近年向近海水体排放污染物量有加剧趋势;4.深圳市社会经济的发展加剧了近海水体的污染;5.深圳市人民生活水平近年有较大的提高,排放的生活污染造成环境危害远远大于工业污染。

Studies on the relationshiop between socioeconomic development and eutrophication in coastal water in Shenzhen (Ⅰ)

In order to study and evaluate Shenzhen coastal water's evolving tendency and analyze its socio-enviromental reasons,the recent years' quality of the coastal water were studied.The results showed that firstly,the level of eutrophication in western coastal area was more serious than the eastern,secondly,the N:P ratios in the coastal water was far more than 16 in the recent years and it belonged seriously P-limiting water,thirdly,after 1998,most factors of the quality of the coastal water had a largely rising tendency,reflecting the more serious tendency of discharging pollutants into the coast,fouthly,socio -economic development exacerbated the pollution of the coastal water.The domestic pollution made more serious effects than industrial pollution with the improving of people's life.
