山林对花椒园昆虫群落结构和稳定性的影响

Influence of Arbores on Insect Community Structure and Stability in Zanthoxylum bungeanum Garden

对云南省昭通市临近山林花椒园及纯作花椒园中昆虫群落组成和结构进行调查,应用群落特征参数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对比研究。结果表明,纯作花椒园的优势集中性指数、害虫亚群落数量高于临近山林花椒园,而临近山林花椒园的物种数、物种个体数、多样性指数、均匀性指数、丰富度指数、天敌数量均高于纯作花椒园。

An investigation was made on the insect community composition and structure in the Zanthoxylum bungeanum garden near the arbores and the pure Z.bungeanum garden in Zhaotong city,Yunnan province,and the community character index were used to study the characters and stability of the insect community.The results showed that the indices of the insect communities,including the species number,species number of individual,diversity,evenness,abundance index and species number of predators were higher and the superiority concentric index in the Z.bungeanum garden near the arbores,species numbers of pest sub-communities were lower than those of the pure Z.bungeanum garden.
