| 摘 要： | 通过巴氏罐诱法对野鸭湖湿地自然保护区段的妫水河南岸的不同生境进行了地表昆虫多样性调查,采集昆虫标本2459头,共有7目25科,其中膜翅目（38.2%）和鞘翅目（30.4%）数量较多,膜翅目中数量最多的是蚁科,鞘翅目中数量最多的是步甲科;在科级水平上,样带Ⅲ的地表昆虫多样性指数最高（1.802）,均匀度也最高（0.612）,样带Ⅱ的丰富度最高（2.845）;所调查的地表昆虫在四个不同的样带中的数量分布差异不显著（P=0.115）.植被多样性影响地表昆虫的整体分布.不同地表昆虫类群对生境表现出不同的分布倾向.

| Abstract: | Litter-layer insects communities in four kinds of habitats on the south bank of Guishui River in Yeyahu Wetland Nature Reserve were investigated by using Baraer traps.2459 specimens which contain 7 orders were collected,of these insects the most abundant groups were found to be Hymenoptera and Coleoptera which take 38.2% and 30.4% of the total each. On family level,the highest diversity（1.802） and enveness（0.612） were habitatsⅢ and the highest richness （2.845）was habitatsⅡ.The distribution of litter-layer insects shows no statistic significance in the four kinds of habitats（p = 0.115）, and the diversity of vegetations determined the distribution of insects. Different kinds of litter-layer insects show different distribution in different habitats. |
