人工林生态系统稳定性研究综述

Review of the Stability Studies on Plantation Ecosystem

在总结国内外稳定性研究的基础上,对人工林生态系统稳定性的概念、内涵和外延,人工林树种的自我维持,多样性和稳定性理论,人为干扰与稳定性的关系,人工林生态系统稳定性指标体系和研究方法等进行综述,指出应加强干扰对人工林生态系统稳定性影响的研究,以及人工林树种和品系选择、组合和搭配技术的研究,提高人工林的遗传多样性、物种多样性和系统多样性,优化人工林生态系统的结构与功能。

On the basis of summarizing the plantation ecosystem stability related researches both at home and abroad,the conception,connotation and extension of plantation ecosystem stability,the self-maintainance mechanism,the diversity and stability theories,the relations between anthropogenic disturbance and the plantation ecosystem stability,the criterion system and assessment methods of plantation ecosystem were comparatively and systematically reviewed in this paper.It was proposed that more attention should be paid to studies on the influence of human disturbance on plantation ecosystem stability,on the tree species or varieties selection,combination and match technology for plantation in order to promote the genetic diversity,species diversity and ecosystem diversity of plantations,and to optimize the structure and function of plantation ecosystem.
