莱州湾多毛类底栖动物生态特征及其对环境变化的响应
Ecological characteristics of benthic polychaete community and its responses to environmental change in Laizhou Bay, Shandong Province of East China
摘要
Abstract
This paper studied the ecological characteristics of benthic polychaete community and its responses to the sea water and sediment environmental variables at 15 sampling stations in Laizhou Bay in 2010, with the results obtained compared with those in 1998, aimed to give a health assessment on the present ecological quality status of the Bay. As compared with those in 1998, the polychaete species composition and biodiversity in 2010 had a greater change, and the dominant species was Capitella capitata. In summer, the Shannon index of the polychaete had significant negative correlations with the sea water and sediment nitrite, oil, Pb, Cu, Zn and Cr concentrations, suggesting that the diversity of polychaete community decreased with the increasing eutrophication in Laizhou Bay. The large input of nutrient nitrogen and the heavy metals pollution had definite negative effects on the polychaete community. The ABC curve and the BOPA index showed that the abundance curve was above the biomass curve, suggesting that the present macrobenthic community was heavily disturbed, while the significant increase of mainly C. Capitata foreshowed the Bay having been polluted to some extant. To strengthen aquaculture management and to rationally use marine biological resources would have great significance for the stability of benthic fauna and the sustainable use of the sea environment.关键词
