摘　　要：以广西融水县红水乡元宝山茶业公司茶园为试验基地,研究了生态管理对茶树节肢动物群落结构和多样性的影响。结果表明:与常规管理茶园比较,生态管理茶园节肢动物群落的物种组成增加15科、84种;害虫类群的个体数量减少55.9%,天敌类群的个体数量增加188.4%;生态管理茶园节肢动物群落的丰富度、多样性指数、均匀度显著高于常规管理茶园,优势指数和群落相似性指数等指标显著低于常规管理茶园。生态管理方式能够提高和恢复茶园节肢动物群落的多样性,有助于实现对茶树害虫的生态控制。The experiment was conducted in the tea plantations of Yuanbaoshan Tea Company, Rongshui County, Guangxi to study ecological management of tea plantation on arthropod community structure and diversity. The results show that arthropod community composition increases by 15 families and 84 species under ecological management, compared with conventional tea plantation management. Individual amounts of pest population decrease by 55.9% and natural enemies increase by 188.4%. Tea plantation species richness, Shannon-Wiener index and Pielou index are significantly higher under ecological management than those under conven-tional management. However, Simpson index and Gowe index are significantly lower under ecological management compared with those under conventional management. The mode of ecological management could improve and restore arthropod community diversity in tea plantations. This mode is readily available for the realization of effective ecological control of tea pests.
