吉林省长白山森工集团近成过熟林现状分析及经营对策

Status Analysis and Management Countermeasures of the Near-mature,Mature and Over-mature Forests of Changbai Mountain Forest Industry Group of Jilin Province

通过对长白山森工集团下属十个森工局近几年的二类调查成果中的近成过熟林固定样地更新调查数据的整理、汇总,计算出十个森工局公顷天然更新株数、具代表性的天桥岭和敦化林业局的公顷各树种株数所占百分比、各树种进阶木所占百分比和各径阶株数百分比,结果表明:长白山森工集团近成过熟林天然更新没有达到良好水平、珍贵树种占比较小、大径阶株数较少。提出了提高近成过熟林的林分质量、林地生产率和森林碳汇数量的经营建议。

Based on the compilation and summary of the survey data of the near-mature,mature and over-mature forests fixed plots in the second-class survey results of the ten forestry bureaus of the Changbai Mountain Forest Industry Group in recent years. The natural regeneration number per hectare of plants forests of ten forestry bureaus,the percentage of the number of trees in each hectare,the percentage of advanced trees in each tree species,and the percentage of each diameter plant of representative Tianqiaoling and Dunhua Forestry Bureau were calculated. The results showed that natural regeneration of near-mature,mature and over-mature forests in Changbai Mountain Forest Industry Group did not reach a good level,the precious tree species accounted for a small amount,and the large diameter plant number was small. The management suggestions of improving the quality of forest stands,forest productivity and forest carbon sinks of near-mature,mature and over-mature forests in near-mature forests were proposed.
