摘要
应用生态位理论，研究了直翅目昆虫群落的空间结构特征。群落在垂直结构上具有分层现象，其组成种类相应地划分为地下栖息型、地表栖息型、草本植物栖息型（含２个亚型），灌木树冠栖息型。不同的种类生态位的宽度是不同的，这主要取决于直翅目昆虫对小生境和食物的选择，往往和物种的生物学特性及植被的分层结构有较为密切的关系。
Spatial niche of orthopteran community is studied in this paper. In vertical stratification, orthopteran insect is grouped into four forms and two subforms, namely subterranean form, geophile form, herb layer form (medium low subform and mdeium high subform), bursh wood crown form. In addition, this paper shows that each species has different niche width. The analysis indicates that spatial niche and its width is based on the resource utilization of micohabitat and food and vegetation structure.
