摘要:森林是陆地生态系统中生物多样性最丰富的生态系统。森林生物多样性对于维持陆地生态系统平衡,保证人类生存和社会经济可持续发展起着不可替代的重要作用。对森林生物多样性进行评估、监测和报告是有效保护生物多样性、合理利用其资源、保证其可持续发展的基础和关键。建立一个有效的生物多样性评价指标体系是对生物多样性正确评估的前提和基础,而合适的指标的筛选是构建这一体系的首要工作。本文从文献分析的角度,分析了生物多样性的评价方法,提出了森林生物多样性评价指标的选择原则以及其中需要注意的一些问题,提出了基于林分水平上的生物多样性评价指标的初步构想,为全面构建森林生物多样性评价指标体系奠定理论基础。

Abstract:Forest is the ecosystem with the richest biodiversity among all the terrestrial ecosystems.Forest biodiversity is critically important for the balance of terrestrial ecosystem,which ensures the livings of human beings and the sustainable social development.The assessment and monitoring on forest biodiversity is the foundation and key to the effective protection of biodiversity and reasonable use of resources.The premise is to establish an effective biodiversity evaluation system to correctly assess the forest biodiversity and selection of appropriate evaluation indices is the first task.In this paper,from the aspect of literature review,the evaluation methods for forest biodiversity are analyzed,and the principles of selection and some key points that should be paid more attention during evaluation are proposed.Finally,a primitive thought about the framework of forest biodiversity evaluation system is proposed,which can provide references for the establishment of the entire forest biodiversity evaluation system.
