在对现有物种多样性与生态功能关系模型进行描述的基础上，提出了物种丰富度、生态恢复力和尺度关系的概念模型。我们认为，物种与规模依赖的生态结构和过程相互作用，决定了功能机会。我们认为，生态弹性是由一个尺度内多样但重叠的功能和在不同尺度上明显冗余的物种产生的，从而在不同尺度上加强功能。功能多样性在尺度内部和尺度之间的分布使得在大范围尺度的生态破坏之后能够进行再生和更新。
We describe existing models of the relationship between species diversity and ecological function, and propose a conceptual model that relates species richness, ecological resilience, and scale. We suggest that species interact with scale-dependent sets of ecological structures and processes that determine functional opportunities. We propose that ecological resilience is generated by diverse, but overlapping, function within a scale and by apparently redundant species that operate at different scales, thereby reinforcing function across scales. The distribution of functional diversity within and across scales enables regeneration and renewal to occur following ecological disruption over a wide range of scales.
