摘要:

作者于1995~1997年对秦巴山区蝗虫资源进行了调查。采用Shannon-Wiener提出的多样性指数(H')公式、Pielou提出的均匀度(E)公式及Simpson提出的优势度(C)公式,计算群落的多样性、均匀度和优势度。结果表明,不同地区、不同生境、不同海拔高度及不同月份,秦巴山区蝗虫群落的物种数目、多样性指数值、均匀度及优势度指数值均有明显差异。这主要与蝗虫的生物学特性直接有关,另外也受到环境因素的影响。

Abstract: Shannon-Wiener’s diversity index ( H′) , Pielou’s evenness( E) and dominance( C) were calculated for the grasshopper communities in the Qinling-Bashan Mountainous Region. The results show that the number of species ,values of diversities , evenness and dominance are distinctly different among different regions ,habits ,the altitudes and the months. These phenomena are mainly related to the characteristics of the grasshoppers and the environments variation.
