摘要
根据典型林分结构的分析,以"近自然林业"理论为指导,提出福建中亚热带天然阔叶林理想结构的指标与标准,包括林层结构、乔木层物种多样性、灌木层中乔木幼树、林分基本蓄积量、材积按径阶分布、林分密度、株数按径阶分布、商品材树种结构等8个指标和各指标的具体标准,旨在为福建中亚热带天然阔叶林可持续经营提供基础依据,为异龄林理想结构的研究提供实例。
Baseed on the analysing of the tipical forests' structure and guided by the theory of NatureApproximating Forestry, the indicators and standards of ideal structure of natural broad-leaved forest in the Midsubtropical zone of Fujian Province are put forward 7 indicators (tree stratum structure, tree species diversity in tree stratum, sapling in the shrub stratum, basic stand growing stock, volume distibution by diameter class, stand density, diameter distribution and tree species structure by merchantable timber) and each standard for the 7 indicators are included in the ideal structure The study on the ideal structure of natural broadleaved forest in the Midsubtropical zone of Fujian Province can provide a foundation for its sustainable management and also can provide an example of study on the ideal structure for uneven aged forest
