| 摘 要： | 对湖南古丈高望界自然保护区直翅目蝗虫类昆虫种类进行了调查,并运用Margalef指数(d)、Menhinick指数(ds)、Shannon-Wie-ner信息多样指数(H')和Pielou均匀度指数(J')分析了该地区直翅目蝗虫类昆虫的物种多样性。结果表明:目前,高望界共发现直翅目蝗虫类昆虫5科13属18种。在种级水平上,种类由多到少依次为斑腿蝗科锥头蝗科斑翅蝗科=蚱科=剑角蝗科。物种丰富度指数最高的科为斑腿蝗科(1.091),最低的科为锥头蝗科(0.295)。物种丰富度Margalef指数(3.206)、多样性Shannon-Wiener指数(1.969)和均匀度Pielou指数(5.391)在不同方面体现了高望界自然保护区直翅目蝗虫类昆虫的多样性状况。

| Abstract: | The author did a preliminary investigation on grasshoppers(Orthoptera) from Mt.Gaowangjie Nature Reserve in Guzhang County of Hunan Province.And the grasshoppers biodiversity in this area are analyzed with Margalef’s index(d),Menhinick’s index(ds),Shannon-Wiener biodiversity index(H′) and Pielou evenness index(J′).The results show that there are 18 species,belonging to 5 families and 13 genera of grasshoppers in Orthoptera in Mt.Gaowangjie.Species are arranged from more to less : Catantopidae > Pyrgomorphidae > Oedipodidae = Tetrigidae = Acrididae.Catantopidae is the family with the highest species richness(1.091) and the lowest is Pyrgomorphidae(0.295).It shows that the grasshoppers biodiversity in different ways in species richness(3.206),Shannon-Wiener diversity(1.969) and Pielou evenness(5.391). |
