不同类型茶园节肢动物群落结构研究

Research on Structure of Arthropod Community in Different Tea Gardens

连续三年分别对樟-茶间作茶园、芒果-茶间作茶园和纯茶园中节肢动物群落结构进行系统调查,并从丰富度、均匀度、优势度指数、稳定性系数值Ss/Si和变异系数ds/dm等方面进行了分析。结果表明:樟-茶间作茶园和芒果-茶间作茶园中节肢动物群落的多样性指数较高,具有更大的丰富度、更丰富的多样性和更高的均匀性,表明樟与茶间作、芒果与茶间作后茶园节肢动物群落内各物种间制约关系强于纯茶园,结构更趋合理。

A three-year investigation on the structure of arthropod community was carried out in three different tea gardens,i. e. pure tea garden,camphor tree-tea and mango tree-tea intercropping gardens.The analysis was conducted from aspects of richness,evenness,dominance index,stability coefficient（ Ss/ Si）and variation coefficient（ ds/ dm）. The results indicated that the diversity indexes of arthropod communities in tea gardens intercropped with camphor and mango tree were higher,and they possessed better richness,diversity and evenness. It showed that the restrictive interactions among different species in arthropod communities in intercropping tea gardens were stronger than those in pure tea garden,and the structures were better.
