摘要: 森林自然度是描述森林状态和确定景观保护价值的重要指标,广泛应用于近自然林业经营和植被恢复与重建。本文在分析森林自然度概念、森林自然度评价类型与方法的基础上,认为森林自然度概念应从森林的自然状况与人类干扰两方面结合起来考虑,森林自然度评价应在潜自然植被参照系研究的基础上采取定性描述与定量表达相结合的方法。林分尺度的自然度评价已形成了较一致的评价方法体系,但应针对不同的植被类型统一制定各植被类型自然度评价的指标选取与赋值标准、权重确定方法和等级划分与命名标准。景观和区域尺度的森林自然度评价对于森林的保护与管理可能更客观和实用,应进一步加强不同组成要素的自然度属性、指标体系及评价方法研究。

Abstract: Forest naturalness is an important indicator in describing forest status and in assessing forest landscape conservation, being widely used in nature-approximating forest management and vegetation restoration and reconstruction. Based on the analyses on the concepts, classifications, and evaluation methods of forest naturalness, this paper proposed that forest feature and human disturbance should be taken into account in the definition of forest naturalness, and an holistic approach combined with quantitative indictors and qualitative description should be considered in the assessment of forest naturalness based on the analysis of reference forest of potential natural vegetation. The standards of assessing forest naturalness at stand scale should be established to decide which attributes to be considered and how to weight these attributes according to different vegetation types, although there was a formed uniform methodology. The assessment of forest naturalness at landscape and regional scales might be more objective and practical for forest conservation and management than the assessment at stand scale, and thus, the naturalness attributes of different components of forest stands, related indictor system, and evaluation methodology at landscape and regional scales should be further studied.
