| 摘 要： | 本文用聚类分析的方法对内蒙古锡林河流域的59种直翅目昆虫的分布规律及其16种生境进行了数值分析，并结合环境条件和实地调查分析了聚类结果。根据直翅目昆虫在不同生境中的分布特点，聚类图将16种生境划分为5个生境型和2个生境亚型；将59种直翅目昆虫划分为10个生境选择相似的生态种组。文中指出：植被类型和水分条件是影响该区直翅目昆虫分布的主要因素。植被组成和垂直结构的复杂程度是决定直翅目昆虫种类丰富度的重要因子。文中还指出了一些昆虫种的生态指示意义，并就草原开垦对昆虫区系的影响进行了讨论。

| Abstract: | In this paper,the distribution of 59 species of Orthopter and 16 types of habitat in the Xilin River Basin district were studied by popularnumerical calssification (Hierachial clustering method). The enviromentalcondition and on-the-spot inverstigation was also used in interpreting theclustering results. The clustering diagram (Fig. 1) shows that 16 habitatsof Orthoptera can be classified into 5 habitat forms and 2 habitat sub-forms,namely typical steppe form, meadow steppe form, sand dune vegeta-tion form of shade-slope, abandoned field form and meadow form (inclu-ding salt meadow sub-form and marsh meadow sub-form). 59 species ofOrthoptera can be classified into 10 ecological species group (Fig. 2), inwhich each one has a similar or the same habitat selection. The authors of this paper think that vegetation types and moisture condi-tion are the main factors influencing the distribution of Orthopterans inthe district. Both the taxonmic composition and physical structure of ve-getation are found to play an important role in the species richness oforthoptera. In addition, the ecological indictor importance of some orthopteranswas demonstrated. The influence of grassland cultivation on fauna of Or-thoptera was discussed. |
