摘要: 以中国东北部长白山过伐天然林为研究对象,通过20多年的连续监测,使用4~14次的复测数据,探索不同经营方式下天然林的生长动态,从森林蓄积量、林分密度、树种组成、径级结构及q值、大中小径级比例等方面,研究天然林的优化结构及其目标,并得出与优化结构相匹配的经营措施,这对现实长白山云冷杉林的经营有普遍的实践意义。

Abstract: After a lot of plots were established in 1986 and 1987, they were remeasured about every two years, so we used remeasured data 4-14 times. According to these data, volume, density, tree species composition, diameter class, q value, etc. were analyzed. Therefore,structure optimization in sustainable forest management of natural forest was concluded. Then we put forward some suggestions in the management which is leading to the optimal stand structure. It is worth of pointing out that this research is couducive to the target of natural forest management in Changbai Mountains, and has practical significance.

Key words: natural forest, overcutting forest, sustainable forest management, structure optimization
