黄河三角洲附近海域底栖动物多样性及其保护措施

Diversity and protective measures of zoobenthon around the Huanghe Delt area

在对黄河王角洲附近海域３０个站点底栖动物调查基础上，辅以文献资料法，综合分析了底栖动物物种多样性，研究了生物多样度以及与均度、单纯度之间的关系，并提出了保护底栖动物多样性的措施。结果表明：该海域共记录底栖动物２２２种，物种较为丰富；生物多样度为０～４．４２，均度为０～２．０１，单纯度为０．１１～１．００；多样度与均度呈显著的正相关，与单纯度呈显著的负相关。

Based on the researches on the zoobenthon in the sea area of Huanghe Delta and theconsulting data, The diversity and the biodiversity of the zoobenthon and the relationship betweenbiodiversity and evenness purity were studied. The measures of protecting the diversity of thezoobenthon was aalso put forward. The results showed that it was abundant in the species, therewere 222 species of zoobethon in this sea area, and that there were the significant positive correla-tions between diversity and evenness, significant negative correlations between diversity and puri-ty. It was also shown that the main causes to imperilis the diversity of zoobenthon in the sea areais the marine pollution, Huanghe’s stopping running and excessive fishing.
