| 通过2006年7月至2008年8月对象山港水域大型底栖动物进行了四季采样分析，采样站位包括13个大面站位和10个电厂站位。共鉴定出大型底栖动物123种，其中软体动物48种，甲壳类33种，鱼类和环节动物多毛类各12种。调查期间，本区大面站位年均栖息密度分别为145.54个/m2和 109.36个/m2，年均生物量分别为28.22g/m2和 30.02g/m2。在电厂站位中，国华电厂年均栖息密度分别为49.58个/m2和46.65个/m2，年均生物量分别为14.49g/m2、15.99g/m2。乌沙山电厂年均栖息密度分别为45.83个/m2、45.21个/m2，年均生物量分别为14.60g/m2、13.81g/m2。研究表明：象山港大型底栖动物分布不均匀，支港流域年均栖息密度、生物量明显高于主港流域。电厂区域的大型底栖动物的栖息密度和生物量均低于全港的平均值。在季节周期变化上，电厂站位的变化差异低于大面站位。 |

| A seasonal research of macrobenthos was carried out in Xiangshan Bay from July, 2006 to August, 2008. There were 13 large sampling stations distributed in the bay and 10 sampling stations in particular location close to the power plant. By the end of the research, 123 species of macrobenthos has been detected. Among them, there’s the 48 mollusk, 33 crustacean, 12 fish and 12 filose. During the research, the average inhabited density in Xiangshan bay were 145.54 and 109.36 ind/m2 respectively, while the average annual biomass is 28.22 and 30.02g/m2. For those area near the power plant, the average inhabited density of Guohua Power plant were 49.58 and 46.65 ind/m2 respectively, while the average annual biomass is 14.49 and 15.99g/m2. The average inhabited density of Wushashan Power plant were 45.83 and 45.21 ind/m2 respectively and the average annual biomass is 14.60 and13.81g/m2. The result shows clear that the macro benthos in Xiangshan Bay is unevenly distributed. Compare to the result in main channel ocean, the biomass and inhabited density in the harbor area were evidently higher. Meanwhile, the biomass and inhabited diversity in area near power plant was much lower than normal area in the bay. The study also shows that for the inhabited density and biomass, the season change has less influence to the power station area than the normal area. |
