摘要:森林自然度作为森林功能区划和群落生境制图的参考指标,在近自然森林经营中具有重要的作用。通过综述国内外有关森林自然度评价的研究进展,从自然度的概念出发,在评价层次、评价指标、评价方法等方面对自然度评价的关键技术进行了综合分析。以森林的演替理论为基础,从时间尺度、空间分布格局和干扰程度3方面分析不同森林群落的自然度,将定性化的分类体系和定量化的指标分级相结合,提出适用于生态学和经营学的森林自然度评价指标体系和方法,以期为森林经营和保护提供理论依据和技术支持。
As the reference standards of the biotope mapping,naturalness assessing and grading are very important to the pre-zoning and later design of the natural forest management.Based on the concept of the degree of close-to-nature in the paper,the key technologies of evaluating the close-to-nature forest were analyzed from the evaluation levels,indica-tors,methods.The evaluation progress,relevant nature degree and degree of the ecological disturbance were reviewed. Considering the structure heterogeneity of different forest communities on the spatial scale,spatial pattern and the inter-ference degree,and combing the qualitative system classification with quantitative indicator according to the forest succes-sion theory,the evaluation system of close to nature forest was established.It provides a theoretical and technical support for the community zoning,mapping and management of the degraded forest.
