高速公路野生植物昆虫群落结构初步分析

Preliminary Study on the Structure of Insect Community on Highway

[目的]分析告诉了高速公路野生植物昆虫群落结构特征。[方法]通过对野生植物荆条进行昆虫调查,用优势集中性指数、优势度、多样性指数及均匀度等生态指标对野生植物的害虫亚群落和天敌亚群落进行了分析。[结果]共调查昆虫10 308头,分属于昆虫纲9个目、43科6、8种以及蛛形纲1科、1种;野生植物害虫亚群落的物种个体数多于天敌亚群落的个体数,害虫亚群落的优势集中性和优势度最大,天敌亚群落的多样性指数大于害虫亚群落。[结论]野生植物荆条中昆虫的丰富度越高,其昆虫的均匀度就越低。

[ Objective ] The research aimed to discuss the community structure character of wild plants and insects. [ Method] By the investigation on the introduced wild-plants of Vitexnegundo varhetero-phyiia, the wild-plants natural enemies sub-community and pest sub-community were analyzed through the ecological index of dominant concentration, dominance, diversity index and evenness. [Result] 10 308 insects were identified, belonging to 9 orders, 43 families, 68 species of Insecta and 1 families, 1 species of Arachnida. The result revealed that the individuals of the pest sub-community were more than that of the natural enemies sub-community, the dominant concentration and dominance of the pest sub-community were the biggest, diversity index of the natural enemies sub-community was more than that of the pest sub-community. [ Conclusion ] The higher abundance of insects in the Vitexnegundo varhetero-phyiia, the lower evenness of insects.
