Abstract

Abstract

The number of species, Margalef's species richness index "d"，Simpson Dominance index "λ", Shannon-Wiener diversity index H'，Pielou's evenness index "J", Hill's diversity numbers(N₁,N₂ and N_+∞),taxonomicdiversity index0, taxonomic distinctness △^* and △⁺ were compared using free-living marine nematodes sampled on 2 occasions from an extensive grid of 20 stations in the Bohai Sea.The rule of change in Margalef's species richnessindex d, Simpson Dominance index "λ",Shannon-Wiener diversity index H',Pielou's evenness index "J", andtaxonomic diversity index △ in the Bohai Sea were studied.The less distance to the Huanghe estuarine, the lower diversity indices and evenness indices and the higher dominant index.The further to the Huanghe estuarine, the higher diversity index and evenness index, the lower dominant index.The change in univariate index related to environmental factors.Huanghe was a very important factor in deciding the community structure of nematode.
