| 摘 要： | 通过对河北省廊坊市平原耕作区的调查,系统研究了不同植被类型中昆虫群落结构、天敌种类、数量以及昆虫群落多样性.初步分析了不同植被类型对昆虫群落和天敌的影响,并初步探讨了作为天敌类群鸟类对昆虫的影响.结果表明：在不同植被类型中昆虫群落结构明显不同,植被类型对天敌种类、数量影响很大.其中杨树纯林的昆虫群落丰富度、多样性指数最高;枣与花生间作的丰富度、多样性指数最低.

| Abstract: | In order to discuss how natural enemies affect the insect communities in Langfang,Hebei province,insect community structure,diversity,species and numbers,pest and natural enemies are systematically studied by using Shannon-wiener diversity index,evenness index and Simpson index.The results show that insect community structures in different plant types are different and vegetations types have a great impact on natural enemy species and their numbers.Insect community richness,diversity index in poplar plantations are the highest,but they are the lowest in the intercropped stands of Chinese jujube with peanut. |
