植物群落功能多样性计算方法

Methods of measuring plant community functional diversity

以性状为基础的功能多样性指数在预测生态系统功能中起到越来越重要的作用。本文对近年来陆续出现的植物群落功能多样性指数进行综述。依据物种多样性指数的组成,功能多样性指数分为功能丰富度、功能均匀度和功能离散度指数。介绍了这3类指数的计算方法,有助于更好、更准确地理解"生物多样性-环境-生态系统功能"的关系。

Plant community functional diversity is based on plant traits, and has been proposed as a key component of predicting ecosystem function. According to the constitution of species diversity, plant community functional diversity is usually described by functional richness, functional evenness, and functional divergence. This paper introduced these three kinds of indices used in plant community ecology, in hopes of better understanding the relationships between biodiversity, environment, and ecosystem functioning.
