| 摘 要： | 根据 2004 年 5 月份的调查资料,选择透明度、盐度、活性磷酸盐、溶解无机氮、硅酸盐、叶绿素 a、浮游植物、浮游动物、底栖生物作为评价因子,利用层次分析法确定了各因子的层次关系和权重,建立了以营养盐和富营养化致害因素、直接效应、间接效应三方面指标为基础的综合评价指数模型,对莱州湾海域的营养水平进行了评价.各站点最终评价结果表明:莱州湾海域磷酸盐、无机氮超标严重,整体已表现出富营养化,其中黄河口和小清河口附近富营养化较为明显,这主要是受到陆源排污和海水养殖的影响. |

| Abstract: | Based on the survey data of Laizhou Bay in May, 2004, salinity, Chl-a, SiO-4, phosphate, DIN, phytoplankton, zooplankton etc. were chosen to be the assessment factors for the eutrophication of coastal waters, and on such a basis, the model for comprehensive evaluation was established. The assessment and classification of nutrient levels were done by a mathematical model. The results showed that Laizhou Bay was seriously polluted by phosphate and DIN, and it was partly at the stage of eutrophication, especially at the mouths of the Yellow River and Xiaoqinghe River. The eutrophication was caused by the land-based pollutant discharge and the sea farming pollution. This basically confirmed to the reality. |
