受干扰长白山阔叶红松林林分结构组成特征及健康距离评估

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)
