The ecological studies which Prof. J. F. Franklin and his colleagues were engaged, in at Andrews Experimental Forest located in Oregon, USA, and the new forestry theory proposed by them are reviewed. The theory focuses on: ① Integration of the ecological functons of a forest (including species preservation and environment protection) with wood production, in order to coordinate forestry development. ② Traditional forestry only concerns itself with the regeneration of trees,whereas new forestry emphasises biological...

The ecological studies which Prof. J. F. Franklin and his colleagues were engaged, in at Andrews Experimental Forest located in Oregon, USA, and the new forestry theory proposed by them are reviewed. The theory focuses on: ① Integration of the ecological functons of a forest (including species preservation and environment protection) with wood production, in order to coordinate forestry development. ② Traditional forestry only concerns itself with the regeneration of trees,whereas new forestry emphasises biological diversity and the maintainance of complex ecosystems. The emergence of "New Forestry" means a new direction in forestry.

该文评介了美国J.F.Franklin教授和他所领导的研究组在美国俄勒冈州Andrews试验林所进行的生态研究以及他们提出的新林业学说,将森林的生态功能(保存物种和保存环境等)和木材生产功能结合起来,使之协调发展;将林业从培育树木、更新树木的角度扩展到对复杂的生态系统的维持相对生物学多样性的维护上;这是新林业理论的焦点所在。从原理上说,新林业代表林业发展的一个新阶段,它有普遍意义,也适用于中国。

This paper discussed the scientific concept of species and the biological nature of species as a natural group. It is high diversity of species that makes it impossible to produce general, applicable and theoretically significant species concepts for all the organisms existing or once existed on the earth. Species communities of composition diversity should have characters which correspond with different biological aspects of individual species, i.e. species diversity should acturally be the biological diversity...

This paper discussed the scientific concept of species and the biological nature of species as a natural group. It is high diversity of species that makes it impossible to produce general, applicable and theoretically significant species concepts for all the organisms existing or once existed on the earth. Species communities of composition diversity should have characters which correspond with different biological aspects of individual species, i.e. species diversity should acturally be the biological diversity of species. There are many different methods to measure the degree of species diversity, but the total number of species should be the most explicit and direct one. A lot of studies in the last decade tried to value how many species exist in the world. The origin of species diversity is through speciation, and its loss through species extinction. The model and mechanism of speciation and extinction and the possible causes were briefly discussed. The author strongly argues that there exists a close relationship between biogeographic analysis and species diversity researches. Pattern identification and component analysis on fauna and flora should be an important part of species diversity researches on a relatively large scale.

本文首先讨论生物物种的科学概念和生物学本质 ,分析物种客观存在的自然属性和物种概念的局限性 ,认为物种的生物学属性和物种多样性的科学属性之间有着本质联系。物种多样性研究的实质是研究生物物种的生物学多样性。度量物种多样性程度有多种方法 ,但物种数目是物种多样性程度最直接、也是最基本的表达 ,估计物种多样性数目是当前国际上物种多样性研究的核心与热点内容。物种多样性产生的根源是物种形成 ,物种绝灭速率是维持物种多样性的关键因素。本文简要总结了物种形成与绝灭的基本模式和机制 ,通过分析生物地理区系与物种多样性研究的密切关系 ,说明物种的区系成份分析是物种多样性大尺度格局研究的重要内容
