摘　　要：采用陷阱法收集茶园蜘蛛,对湖南茶区代表性茶园的蜘蛛多样性及种群动态进行了调查。一共调查到蜘蛛1457头,隶属18科,32属,41种。陷阱法收集的茶园蜘蛛大多数为游猎型蜘蛛,其中狼蛛科(Lycosidae)为优势科,前凹水狼蛛(Pirataprocurvus)为优势种。茶园蜘蛛群落多样性、均匀度、丰富度和优势度指数跟时间有一定关系,多样性和丰富度的波动较大,而均匀度和优势度指数波动不大。Spider diversity and population dynamics were investigated in a representative tea garden using pitfall traps. A total of 1457 spiders, attached to the 18 families, 32 genera, 41 species were investigated. Most of the trapped spiders were wandering species. Lyeosidae was the dominant familie while Pirata procurvus the dominant specie. The diversity, evenness, richness and dominance indices of the spider community were Time-related. The fluctuation of the diversity and richness indices were larger, while those of evenness and dominance indices smaller.
