摘要: |
2005年秋季对连云港核电站周围海域大型底栖动物群落组成 和多样性特征进行了调查,并与1998年调查资料进行分析比较,以研究核电站建设时期(1999~2005年)周围海域的大型底栖动物群落组成和多样性变 化。研究表明,2005年调查的优势种以多毛类居多,而不是1998年的软体动物和棘皮动物,且调查出现的总种数明显少于1998年;大型底栖动物丰度值 高于1998年,但生物量却大大减少,Shannon-Wiener多样性指数H′和Pielou均匀度指数J′都高于1998年。 |

Comparison of community structure and biodiversity characteristics of macrobenthos between 2005 and 1998 in the Lianyungang Nclear Pwer Sation alongshore sea area |
|
Abstract: |
This article mainly compared the community structures and biodiversity characteristics of macrobenthos between 2005 and 1998 in the Lianyungang Nuclear Power Station alongshore sea area. The result shows that polychaete is a dominant species in this study rather than mollusk and echinoderm in 1998 and the total individual number of the species is smaller than that in 1998; the richness value of macrobenthos in this study is bigger than that in 1998, which is contrary to the biomass; both Shannon-Wiene index and Pielou index are bigger than those in 1998. |
