摘要
通过分析渤海湾中与富营养化有关的主要因素,综合了化学指标、浮游植物指标并考虑到细菌指标,提出渤海湾了海水富营养化的二级模糊综合评价方法,对渤海湾富营养化状态进行了评价,并用加权平均原则对结果进行了处理。对评价结果进行排序,发现渤海湾北部近岸海域和南部的养殖区富营养化程度严重,且夏季最高,秋季最低。
Through analysis of the main factors of eutrophication in Bohai Bay and synthesis of chemistry index and phytoplankton index and bacteria index, the method of two-grade fuzzy synthesis assessment for the seawater eutrophication is put forward. The method could be applied to assess the eutrophication level in Bohai Bay. The result is transformed by weighted-average principle, through arranging final assessment result,it can be found the eutrophication is serious in north costal water and south fishery in Bohai Bay. The level of eutrophication is the highest in summer and lowest in auturnn.
