摘要：

为了解椒江口滩涂大型底栖动物群落格局与多样性, 揭示其对环境变化的响应规律, 作者于2007年10月、2008年1月、4月和7月在椒江口南岸和北岸潮间带, 沿河流到海洋方向共布设6条采样断面进行大型底栖动物调查。分析了大型底栖动物种类组成、栖息密度和生物量的时空变化特征, 在此基础上运用α,β和γ多样性测度方法对大型底栖动物多样性进行分析, 同时探讨了大型底栖动物群落结构对环境变化的响应方向及程度, 结果显示: (1) 6条断面共记录到大型底栖动物78种, 总种数随季节变化显著, 在空间上沿河流到海洋方向呈升高趋势; (2) 栖息密度的季节变化不显著(P=0.145>0.05), 但空间变化显著(P=0.017<0.05), 生物量的季节变化显著(P=0.012<0.05), 空间变化极显著(P=0.004<0.01); (3)β和γ多样性指数定量显示了椒江河口区域滩涂环境的多变性和大型底栖动物群落的多样性和更替性。

Abstract

In order to understand the community pattern and diversity of macrozoobenthos in an intertidal flat of the Jiaojiang Estuary, and to reveal the response of macrozoobenthos to environmental change, we designed six intertidal sampling transects along the banks of the Jiaojiang Estuary, in October 2007, January, April, and July 2008, respectively. Temporal and spatial variation of species composition, density, and biomass of macrozoobenthos were recorded and analyzed; furthermore, α, β and γ diversity indices were applied to measure the biodiversity of macrozoobenthos in the study area. The response of macrozoobenthos to environmental change was also studied. The main results were as follows: (1) A total of 78 macrozoobenthos species were recorded. There was a significant seasonal variation of macrozoobenthos species. Besides, the species number has an increasing trend from river to sea in both banks. (2) Macrozoobenthos density demonstrated insignificant seasonal variation but significant spatial variation, whereas biomass did not vary significantly both seasonally and spatially. (3) β and γ biodiversity indices showed that the environment was changable and the community pattern and biotope of macrozoobenthos were diversified.
