| 摘 要： | 基于1986～2006年上海海域水质调查资料,应用模糊数学模型对上海海域水体水质的现状及1986～2006年各年度海水水质进行了综合评价,并在此基础上分析了21 a间的海水水质变化趋势.结果表明:20世纪80年代,上海海域海水水质相对较好,但进入20世纪90年代后,随着工业化进程的加速和氮肥用量的快速增长,上海海域水质迅速恶化,均为Ⅳ级水质;2000年之后,上海海域海水水质继续恶化,但恶化速度相对缓慢,主要污染物质也由重金属污染过渡到营养盐污染.本文更客观、全面地分析了上海海域水环境质量状况,为政府制定环保措施提供依据.

| Abstract: | Based on the investigation data around Shanghai sea area from 1986 to 2006,the fuzzy comprehensive evaluation method was used to evaluate the seawater quality and analyze the variation of seawater quality for last 21 years.The results show that the seawater quality was good comparatively in 1980s,along with the rapid industrialization process and a large number of nitrogenous fertilizers,the seawater quality deteriorated rapidly in 1990s,and it continued to deteriorate slowly after 2000.The main pollutants ... |
