摘要: 从综合丰富度、均匀度、多样性的角度评价林分群落物种多样性,提出物种多样性综合指数的概念,突破传统以单方面描述物种多样性的局限。以湖南省平江县福寿国有林场为案例,利用24块样地数据,对筛选出的指标运用CRITIC法确立权重,得出各样地物种多样性综合指数的计量模型,既反映了物种多样性指数的传统信息,又反映了实际样本数据的信息,使得综合指数的结果更加合理。

关键词: 物种多样性综合指数, CRITIC法, 丰富度, 均匀度

Abstract: Through use of richness,evenness and diversity to evaluate species diversity,the concept of Species Diversity Composite Index is proposed,breaking traditional and unilateral limitations of species diversity description.With multiple raw data based on selected indicators and use of CRITIC law the weights are established and each forest Species Diversity Composite Index measurement model developed,which reflects both the diversity indices of traditional information and the actual sample data. This makes the results of the composite index more reasonable and objective.

Key words: species diversity composite index, CRITIC law, richness, evenness
