| 摘 要： | 内蒙古典型草原金龟总科昆虫幼群落组成以东方绢金龟和弓斑常丽金龟为优势种，在两种主要植物群落类型大针茅草原和羊草草原中无明显差异。金龟总科昆虫幼虫的季节动态在０这两类草原均表现为春季和秋季密度较高，而夏季密度较低，在土壤中的垂直分布式随季节的变化而变化。金龟总科昆虫幼虫群落对长期持续放牧扰动的响应主要表现为密度降低，特别是东方绢金龟种群密度降低。 |

| Abstract: | The community of Scarabaeoidea larvae in NeiMongol typical steppe was studied from 1992 to 1996. In main typesof NeiMongol typical steppe, Stipa grandis steppe and Leymus chinensis steppe,the dominant species are same, and they are Serica orientalis Motrchlsky and Cyriopertha arcuata (Gebler).In spring and autumn, the density of Scarabaeoidae larvae are higher than that in summer.The vertical distribution of Scarabaeoidae larvae also changed with the seasons changing. The main effects of activity of grazing are that it can make Scarabaeoidae larvae density decrease. |
| Keywords: | NeiMongol typical steppe larvae of Scarabaeoidae dynamic of community activity of grazing |
