摘要
为了解广西生态茶园与普通茶园节肢动物群落结构特点及其稳定性,本文采用Shannon-Wiener多样性指数(H′)、群落物种优势度指数(D)、丰富度指数(J)、物种均匀度指数(E)等分析了茶园节肢动物群落的多样性结构,应用群落相似度指数对生态茶园和普通茶园节肢动物的群落相似性进行了分析,用灰色关联度方法综合分析多样性指数与优势度、均匀度等6个特征参数间关系的密切程度。结果表明,在广西茶园节肢动物共34种,其中害虫(螨)17种,优势种群是:小贯小绿叶蝉Empoasca onukii Matsuda、茶蓟马Scirtothrips dorsalis Hood、蚜虫、白粉虱Trialeurodes vaporariorum Westwood;天敌8种,优势种群是:棕管巢蛛Clubiona japonicola Boeset Str.、八斑球腹蛛Theridion octomaculatum Boes.et Str.、异色瓢虫Harmonia axyridis(Pallas);中性昆虫9种,优势种群是:蚊虫、蚁类。多样性指数、群落均匀度指数与物种优势度在生态茶园比普通茶园高。生态茶园的群落稳定性比普通茶园的强。不同茶园间的群落相似性指数q在0.444~0.9355之间,群落间相似性关系在中等不相似与极度相似之间。与多样性指数密切相关的前3位群落特征参数依次是群落物种优势度、益害物种的个体数比、丰富度,其中关系最密切的特征参数是群落物种优势度。研究结果为茶园害虫的综合防控提供了理论依据。
In order to clarify the structure and stability of arthropod community in different tea gardens of Guangxi.Shannon-Wiener index,species evenness and richness indices were used to study the distributional trends of community structure,dominant species and abundance of tea Gardens.Community similarity index was used to analyze the community similarity of different types of tea gardens.The relationship between the diversity index and other characteristic parameters was comprehensively analyzed by using the grey relational degree method.The results showed that:A total of 34 arthropod species were collected.Among them,17 were pests,of which the major species were Empoasca pirisuga Matumura,Scirtothrips dorsalis Hood,Myzus persicae Sulzer.,and Trialeurodes vaporariorum Westwood;8 species were natural enemies,major species were Clubiona japonicola Boeset Str.,Theridion octomaculatum Boes.et Str.,and Harmonia axyridis(Pallas);9 were neutral species,major groups were mosquitoes,ants,fireflies.Diversity index,community evenness index and species dominance index were higher in ecological tea gardens than traditional tea gardens.The stability of community in ecological tea garden was stronger than in traditional tea garden.Similarity index(q)among different tea gardens ranged from 0.444~0.9355,and similarity relationship between communities ranged from moderate dissimilarity to extreme similarity.The first three community characteristic parameters closely related to the diversity index were community dominance,spieces riches and Sn/Sp,and the most closely related to the diversity index was community dominance.
