生物多样性熵值测度指标的应用与分析

Analyses on Assessment Index of Biodiversity

以一般生物多样性指标为基础,对熵值测度指标进行了研究,用熵值及其他多样性指标分析评价了新疆克拉玛依荒漠植被的生物多样性。结果表明,熵值测度指标与一般生物多样性指标在机理上有对应性,不仅可作为物种多样性、生态优势度、物种丰富度的优良评价指标,而且可以说明系统的物种对系统的贡献大小及其演化方向。

The paper is based on ordinary index to assess biodiversity.Entropy is an important object to study.Entropy and other biodiversity indexes is used to assessed wilderness vegetation of Kelamayi in Xinjiang.The result shows entropy and other biodiversity indexes have corresponding in principle.Entropy is not only a fine assessed index as species diversity,ecological dominance and species richness but also manifest species of system which contributes to and evolutes to the system.The paper provides the new base to the assessment index of biodiversity.
