中文摘要：

对云南昭通市4种不同种植模式花椒园（花椒-玉米-大豆园、花椒-大豆园、花椒-玉米园、花椒园）昆虫群落的组成和结构进行调查，采用群落特征指数和主分量分析法对不同种植模式花椒园昆虫群落特征及其稳定性进行了研究．结果表明：研究区花椒园共发现326种昆虫；与单一种植花椒园相比，问作套种作物花椒园昆虫群落的丰富度指数、多样性指数和均匀度指数均较高，而优势度指数较低；不同种植模式花椒园昆虫群落多样性指数值大小依次为花椒玉米大豆园〉花椒大豆园〉花椒玉米园〉花椒园．花椒、玉米、大豆间作套种系统中昆虫群落的稳定性较好．

英文摘要：

An investigation was made on the insect thoxylum bungeanum garden with corn-soybean -Z. community composition and structure in a Zan- bungeanum intereropping, soybean - Z. bun- geanum intereropping, corn - Z. bungeanum intereropping, and only Z. bungeanum planting in Zhaotong City of Yunnan Province, and the community character index and principal component analysis were used to study the characters and stability of the insect community. A total of 326 insect species were recorded. In intercropped plots, the abundance, diversity, and evenness index of insect community were higher while the dominance index was lower, compared with those in monocultured Z. bungeanum plot. The diversity index of insect community decreased in the order of corn-soybean-Z, bungeanum intercropping 〉 soybean- Z. bungeanum intercropping 〉 corn- Z. bungeanum intercropping 〉 only Z. bungeanum planting, and the insect community in cornsoybean -Z. bungeanum intercropping plot was relatively stable.
