黄河三角洲附近海域浮游动物多样性研究

Zooplankton diversity around the Huanghe River Delta

以文献资料和定性调查相结合的方法，综合分析了黄河三角洲附近海域浮游动物物种多样性；以定量调查结果，探讨了浮游动物多样度以及与均度、单纯度之间的关系。结果表明： 该海域浮游动物物种占中国海的５－７ ％ ，占渤海的５１－７％ ；浮游动物多样度在０－１０ ～２－２８ 之间，均度在０－０２～０－９７ 之间，单纯度在０－１４ ～０－９９ 之间；多样度与均度呈显著的正相关，与单纯度呈显著的负相关。

By means of the qualitative research and the historic materials, the zooplankton diversity in the Huanghe River Delta was analysed. According to the quantitative results, the relation of the zooplankton diversity with the eveness, simplex were studied. The results shown that the species in the Huanghe River Delta constitute about 5 8 per cent of that of the Chinese sea, about 52 3 per cent of that of the Bohai, the degrees of the zooplankton diversity, eveness and simplex were individually 0 10～2 28,0 02～0 97,0 14～0 90,the degree of the zooplankton diversity presents the outstandingly positive correlation with eveness and the negtive correlation with simplex.
