近年来,工厂化海水养殖的规模不断扩大,养殖废水的排放给近海生态环境带来了巨大影响。该研究以位于山东省烟台市牟平区的姜格庄工厂化海水养殖区为取样点,分析了养殖废水对附近海域水环境的影响。结果表明,养殖废水排放口附近水体中氮、磷营养盐含量较高;养殖废水排放区与非养殖区水体中营养盐结构明显不同,即养殖废水对近岸水体中的营养盐结构影响较大。
In recent years, the scale of factory-made marine aquaculture has been continuously expanded, and the discharge of aquaculture wastewater has brought tremendous impact on the coastal ecological environment. In this study, Jianggezhuang factory mariculture zone located in Muping District, Yantai City, Shandong Province was sampled to analyze the impact of mariculture wastewater on the water environment in the nearby sea area. The results showed that the contents of nitrogen and phosphorus in the water near the discharge of aquaculture wastewater were relatively high. The nutrients in the aquiculture wastewater discharge area and the non-aquaculture water area were obviously different, that is, the aquaculture wastewater greatly affected the nutrient structure in the coastal waters .
