摘要:

生物多样性保护是森林可持续经营一个重要目标。生物多样性指标,大致可分为三类:物种和群落,结构,过程。物种只是一个不完整的替代指标。本文综述了林分尺度结构多样性指标的研究进展,可分为与距离有关的林分结构多样性指标和与距离无关的林分结构多样性指标,它们反映林分的树木大小多样性、树木的水平分布格局、树种的空间隔离程度及空间结构的复杂性。文章最后讨论了进一步要研究的问题。

关键词: 生物多样性, 林分结构多样性指标

Abstract:

Biodiversity conservation has become one of the important goals of sustainable forest management. Biodiversity indicators can be of three principal types: species and communities, structures, and processes. Species can only serve as an incomplete, surrogate measure. The progress in indicators of structural diversity within stand is reviewed in the paper. It can be included as distance independent indicators and distance-dependent indicators, which describe tree size diversity, horizontal pattern of trees, intermingling of two tree species, and spatial structure complexity. The study trends are discussed.

Key words: Biodiversity, Indicators of structural diversity within-stand
