摘　　要：2 0 0 0年 4月～ 2 0 0 1年 10月对白芨滩国家自然保护区内三种不同人工固沙封育区草地景观类型进行了昆虫群落的调查 ,得出 :封育区内植物群落的组成结构不同 ,显著影响昆虫群落种类的组成和结构 ,植物群落组成和结构愈复杂 ,昆虫群落组成就愈丰富。The investgation for the insect community was carried out in the Bai-Ji-Tan National Nature protected zone where there are main three types of vegetation that have significant differences in the composition and structure in the artificial sand-fixation zone. The conclusion can be drawn as follow: The obvious differences about the composition and structure to the plant community affect the composition and structure of the insect community in the artificial sand-fixation zone. The more complex the plant community is, the more plentiful the insect community is , and the composition of the insect community tends to develop from the single community.
