中文摘要：

为明确花椒玉米间作园和纯作花椒园中昆虫群落结构和周年变化情况，2011年对云南省昭通市花椒玉米间作园与纯花椒园的昆虫群落组成进行调查，并应用群落特征参数与主成分分析法对昆虫群落特征、时间格局及群落稳定性进行了研究。结果表明，花椒玉米问作园比纯花椒园群落组成更为复杂，花椒玉米间作园和纯作花椒园的昆虫物种数分别为202种和150种，个体数分别为2362个和1847个，群落多样性指数分别是4．0577和3．7666，均匀性指数分别是0．7602和0．7468，丰富度指数分别是26．6416和20．4561，优势度分别是0．0798和0．1108，优势集中度分别是0．0319和0．0438，即花椒玉米间作园的昆虫物种数、个体数、群落多样性、丰富度、均匀性指数均比纯作要高，而昆虫的优势度比纯作有所降低，而且昆虫群落的稳定性更好，害虫大发生的几率相对较小，花椒玉米问作模式是比较理想的种植模式。

英文摘要：

In order to figure out insects community composition and change of Zanthoxylum bungeanum intercropped with corn and monoculture garden, insects community composition of Z. bungeanum inter cropped with corn and monoeulture garden had been studied in 2011 in Zhaotong City, Yunnan Prov ince, A and the community character index and principal component analysis were used to study the characters, temporal pattern, and stability of the insect community. The results show that insects com munity composition of Z. bungeanum intercropped with corn is more complex than monocuhure garden, the number of insect species were respectively 202 and 150, the number of individuals were respectively 2 362 and 1 847, community diversity index were respectively 4. 057 7 and 3. 766 6, evenness index were respectively 0. 760 2 and 0. 746 8, the richness index were respectively 26. 641 6 and 20. 456 1, the dom inance index were respectively 0. 079 8 and 0. 110 8, the dominant concentration index were respectively 0. 031 9 and dominance 0. 043 8 in Z. bungeanum intercropped with corn and monoculture garden. In sect species number, diversity, richness and evenness index in Z. bungeanum intereropped with cornwere higher than in monoculture garden. In the garden of Z. bungeanum intercropped with corn, insect dominance decreased, insect community had better stability, probability of pest outbreak was relatively small. Therefore, Z. bungeanum intercropped with corn was an ideal planting mode.
