摘　　要：基于实测调查获取的研究区水质参数,本文采用单因子指数法、综合污染指数法和主成分分析法对研究区29个监测站位的水质进行评价,结合养殖区的空间分布以及该海域的水动力条件对研究区水环境质量进行综合分析。研究结果显示,水产养殖活动对该海域水质状况造成显著影响,但该海域涨落潮具有明显的规律性,水流交换能力强。因此整体上看,大连海王九岛水质状况仍满足国家水产养殖标准。但为了该海域长期健康发展,防范水产养殖区水质污染,合理科学规划渔业养殖活动仍然是非常有必要的。The single factor indexing,comprehensive pollution indexing and principal component analyzing methods were used to evaluate the water quality of 29 monitoring stations in the studying area basing on the measured water quality parameters in combination with the spatial distribution of the aquaculture area and the hydrodynamic conditions.The results showed that aquaculture activity has a significant impact on the water quality,and the fluctuation tide has a strong flow exchange capacity.On the whole,the water quality meets the national aquaculture standards near Neptune Nine Island area,Dalian.However,for the long-term and healthy development of the sea area,it is absolutely necessary to prevent water pollution in aquaculture areas and plan fishery and aquaculture activities reasonably and scientifically.
