摘要：

根据香农-维纳信息多样性指数的定义,提出了生物量多样性指数的计算公式,并以此分析了枣园生态系统中节肢动物群落特征。结果表明,枣园节肢动物各类群的生物量多样性指数比数量多样性指数变化更为敏感,更能反映枣园生态系统中节肢动物群落的结构特征。作者认为,利用生物量多样性指数分析群落的结构特征更切合实际

关键词: 枣园生态系统, 节肢动物群落, 生物量多样性

Abstract:

The diversity was an important descriptor of community diversity and ecologists had proposed numerous indexes. The previous indexes that assumed all species were equal and came from the same tropic level were criticized. According to the definition of Shannon-Wiener, a new index was developed for measuring community diversity. The diversity index of biomass was sensitive to the population dynamics in arthropod pests and natural enemy' community. The diversity index gave a more faithful representation of the arthropod community characteristics in the jujube yard ecosystems.It was the better index for measuring community diversity because incorporating other difference among species as a component strengthened the functional aspect of species diversity measurement.

Key words: jujube yard ecosystems, arthropod community, biomass diversity
