针对北京山区不同阶段的油松林特点,规划设计出每个阶段油松林的发展目标类型,并制定出了相应的经营措施。根据林分结构特征及其功能的定位,将涉及到的17块油松林样地分为4个阶段,即竞争生长阶段、竞争生长向质量选择阶段的过渡阶段、质量选择阶段和近自然阶段。每个阶段均按照发展目标类型、主要指标、近期经营措施等方面进行设计。本研究期望对北京人工林的可持续经营和近自然化改造提供科学参考。
Aiming at the characteristics of Pinus tabulaeformis forest in different stages of Beijing mountainous area, we plan to design the development target types of Pinus tabulaeformis forest in each stage and make the corresponding management measures. According to the structure and function of stand, the 17 plots of Pinus tabulaeformis forest involved were divided into four stages, that is, competition growth stage, transitional stage from competition growth to quality selection stage, quality selection stage and near-nature stage. Each stage is designed in accordance with the type of development goals, major indicators, recent management measures and other aspects. This study is expected to provide a scientific reference to the sustainable management and near-natural transformation of Beijing plantation.
