重庆优质绿茶产区茶园蚂蚁物种多样性研究

Study of ant biodiversity in tea gardens of high quality green tea-producing areas in Chongqing

通过田间系统调查,对重庆永川、南川和荣昌3个区县优质绿茶产区茶园蚁科昆虫群落进行了研究,鉴定出蚁科昆虫30种,其中重庆新纪录种29种,主要优势种有9种;不同海拔高度茶园物种丰富度指数为3-12,Shannon–Wiener多样性指数最高为1.64,最低为0.15,Pielou均匀度指数最高为0.74,最低为0.09,Simpsom优势度指数最高为0.77,最低为0.09。

Sample-plot survey method was conducted to study the biodiversity of ant species from the tea gardens in main tea-growing areas of Chongqing. A total of 30 species of Formicidae including 9 dominating species were identified in the tea gardens in main tea-growing areas of Chongqing. The species richness of ant communities from the tea gardens at different altitudes were 3-12 species, Shannon-Wiener diversity indexes were 0.15-1.64, Pielou evenness indexes were 0.09-0.74, and Simpsom dominant indexes were 0.09-0.77.
