摘 要:用"五点式"取样法对石河子农耕区不同林地地被中的昆虫群落结构多样性进行了调查,共采集到昆虫31种,分属8目14科,共计1099头。结果表明:杨树老林地被昆虫群落的丰富度最高(为23),幼榆林次之(为14),苗圃和葡萄的最低(均为7)。多样性指数幼杂林最高(为1.8613),苗圃次之(为1.6833),幼榆林最低,为0.8534。The diversity characteristics of insects community structrues in different types of woodlands in Shihezi agriculture cultivation areas were studied by sampling method in five spot from July to September. In all investigation periods, thirty - one kinds of insect species were collected, which are belonged to eight orders, fourteen families. The results show that the richness index of insect community in old poplar woodland is the highest one,that in young elm woodland is the second and that in nursery and grape woodlands are the lowest. The diversity index of insect community structure in young shaw is the highest, that in nursery is the second and young elm woodland is the lowest.
