本文从群落内部因素和干扰对群落动态的影响两方面分析红松林的动态过程。群落内部因素分析结果表明:针叶树种多为苗库策略树种,红松尤为明显,林下生活力(耐阴性)不同的树种其径级结构分布不同,在林下生活力较强的树种中,采用不同林下生活策略的树种其林冠层林木的早期年轮宽度分布不同;林木的年轮宽度变化与林木被压和释压显著相关。在林木干扰历史重构方面,利用取自红松和鱼鳞松的200多个年轮盘的年轮宽度数据重构林分干扰历史并分别与红松和鱼鳞松的更新历史进行相关关系分析,结果表明。在天然红松林中红松是以苗库策略等待干扰为之创造适宜条件进行更新的;而鱼
This paper analyzes the dynamic process of Korean pine forest from the aspects of community internal factors and the impact of disturbance on community dynamics. The analysis of internal factors in the community showed that coniferous species were mostly tree seedlings planted in the seedling depot and especially in the Korean pine. The species distribution of different tree species with different viabilities (negative tolerance) The distribution of early ring width of forest canopy varies with tree species under different forest life strategies. The change of tree ring width is significantly related to the pressure and pressure relief of forest trees. In reconstructing the historic disturbance of forest disturbance, the disturbance history of the forest was reconstructed using the annual ring width data of more than 200 annual disks from Pinus koraiensis and Pinus sylvestris var. Mongolica and analyzed respectively with the updated history of Pinus koraiensis and Pinus sylvestris var. The results show. In the natural Korean pine forest, Korean pine is the Miao reservoir strategy to wait for interference to create suitable conditions for updating; and fish
