黄河三角洲潮间带动物多样性的研究

以１９９６年黄河三角洲潮间带动物定性调查结果，分析了黄河三角洲潮间带动物物种多样性；以定量调查结果研究了潮间带动物多样度以及与均度、单纯度的关系。研究表明：该区共鉴出潮间带动物１９３种，隶属于１３个门１５个纲４０个目９４个科；潮间带动物多样度为０～１．７０，均度为１～１．００，单纯度为０．２２～１．００；多样度与均度呈正相关，与单纯度呈负相关关系。

STUDY ON THE DIVERSITY OF INTERTIDAL ZONE ANIMALS IN THE YELLOW RIVER DELTA

The diversity of the intertidal zone animals in the Yellow River Delta has been analysed by using the results of the intertidal zone animals qualitative investigation in 1996; using the results of quantitative investigation, the diverse degree of interidal zone animals and its relations with the average and pure degrees have been stodied. The study shows that there exist 193 species of intertidal zone animals in the arera; that the diverse degrees of intertidal zone animals are between 0 and 1.70, the averages are between 0 and 1 .00 and the pure degrees are between 0.22 and 1.00; and that the diverse degree is positively. correlated to the average,but negatively. correlated to the pure degree.
