海南霸王岭山地雨林理想结构的指标与标准(standards)探讨

A Discussion on the Indicators and Standards of Ideal Structure of Montane Rainforest in Bawangling of Hainan Province

根据典型林分结构的分析,结合海南霸王岭原始热带山地雨林林隙特征,以"近自然林业"理论为指导,提出海南霸王岭山地雨林理想结构的指标与标准(standards),包括林层结构、乔木层物种多样性、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、特类～三类商品材树种结构等7个指标和各指标的具体标准(standards),旨在为海南霸王岭山地雨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。

Based on the analysis of the typical forests' structure, the gap characters of virgin tropical montane rainforests and guided by the theory of NearNature Forest Management, the indicators and standards of ideal structure of montane rainforest in Bawangling of Hainan Province were put forward. 7 indicators (tree stratum structure, tree species diversity in tree stratum, basic stand growing stock, volume distribution by diameter class, stand density, diameter distribution and tree species structure by merchantable timber of top class to class third ) and the standards for each of the 7 indicators were included in the ideal structure. The study on the ideal structure of montane rainforest in Bawangling Forestry Area of Hainan Province could provide a foundation for their sustainable management and also could provide an case study on the ideal structure for uneven aged forest.
