摘要
通过样地调查对不同干扰方式产生的过伐天然林、次生白桦林和人工落叶松林等群落的结构组成进行分析和分类探讨 ,并选取能够表征结构完整性和稳定性的一些指标因子 ,利用健康距离法对长白山阔叶红松林区的森林生态系统健康进行了评估实践 ,结果按顺序依次为 :原始阔叶类 0 14 <结构转换型0 2 3<结构保留型 0 32 <结构破坏型 0 33<严重干扰类型 0 4 4 <次生白桦林 0 5 3<人工落叶松林0 6 8.以期对阔叶红松林生态系统的恢复和区域林业可持续发展提供参考 .
Through samples investigation,this paper analyzed and classified the community structures of overcutting original forests,secondary birch forests and larch plantation forest under different disturbances.At the same time,some indexes which can reflect the integrity and stability of stand structure were selected.Health Distance (HD) method,a new idea,was attempted to assess ecosystem health of Korean pine and broadleaved mixed forest in Changbai Mountains.The results showed that the health degree was in order of original broadleaved stand (0.14)<structure switched stand (0.23)<structure reserved stand (0.32)<structure destroyed stand (0.33)<heavy disturbed stand (0.44)<secondary birch stand (0.53)<larch plantations (0.68).Hopefully,it will be a helpful reference on the restoration of Korean pine and broadleaved mixed forest and on the regional forestry sustainable development.
