关于蝗虫类种属比率的研究

:(1)当代蝗虫类的种属比率 ,单型属、寡型属和多型属的百分比同鸟类非常接近 ,即单型属高居首位 ,寡型属次之 ,多型属沦于末位。 (2)蝗虫类分布在中国的有217属 ,其中单型属、寡型属和多型属的百分比同全世界的情况完全相反 ,多型属最多 ,寡型属居中 ,单型属最少。(3)中国的蝗虫类单型属同近缘属的主要区别特征标准较为一致 ,属的地位相对稳定

On the Species-Genus Ratio of Grasshoppers

The species_genus ratio of grasshoppers of the world and monotypic genus from China are studied. The results may be summarized as the following:(1)At present, species_genus ratio and the percent in monotypic, olygotypic and polytypic genus of grasshoppers are close to those of birds in the world; i.e. monotypic genus occupying the first place, olygotypic genus in the middle, and polytypic genus at the last place.(2)There are 217 genera of grasshoppers in China, among them polytypic genus occupying the first place, monotypic genus at the last place. They are different from those of the world.(3)The characteristics of monotypic genus of grasshoppers from China are as same as in the rule, so the place of monotypic genus is relatively stable.
