摘　　要：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。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.
