摘　　要：为全面评估浙江目标海域生态环境的基本情况及变化趋势,于2020年分两批次对浙江海域20个站位点的理化指标和生物学指标进行系统测样调查,并采用改良后的层次分析法对浙江目标海域整体生态环境进行评估。结果表明,目前目标海域水体质量整体保持良好水平,但海域的水体富营养化程度在贫营养与中度营养间来回波动,部分区域已经出现了富营养化的趋势,需要引起足够的环境关注并加强后续的保护措施。In order to comprehensively assess the basic conditions and changing trends of the ecological environment in the target marine area of Zhejiang,a systematic sample survey of the physical and chemical indicators and biological indicators of 20 stations in the sea area of Zhejiang was carried out in two batches in 2020,and an improved AHP method is used to assess the overall ecological environment of surveyed marine area.The results show that the overall water quality maintains at a good level,but the degree of eutrophication in the sea area fluctuates between oligotrophic and moderate nutrition.There has been a trend of eutrophication in some areas,which requires sufficient environmental attention and the follow-up protective measures are to be taken.
