摘  要：
采用矩阵模型预测未干扰下长白山阔叶红松林不同初期密度和直径分布林分300年的动态生长过程,比较12种不同采伐方案(最小采伐直径分别为70、60、50、40cm,采伐周期分别为10、20、30年)经过300年采伐保留林分的密度、断面积和林分收获量。结果表明,无论初始状态如何,未干扰林分经过约200多年后变化趋于平稳,径阶结构、断面积均能达到近似相等的稳定状态;采伐以最小采伐直径60cm、采伐周期20年较适宜。得出了不同采伐方案的收获量及保留林分各因子变化规律。

摘  要：
The three-hundred years dynamic growth process of the unmanaged stands of uneven-aged mixed forest with different primary densities and diameter distributions in Changbai Mountain was predicted with matrix model.The stand densities,basal area and stand harvest with different management projects during 300 yr were compared,in which the diameter limit included 70,60,50 and 40 cm,and the cutting cycle included 10,20 and 30 yr.The results showed that whatever the initial state was,after about 200 years,the changes of the unmanaged stand became quite stationary,and diameter class structure and basal area would achieve an approximately equal steady state.The management regime which the diameter limit was 60cm,and the cutting cycle was 20 yr was the best.The changing rules of various factors in different management regimes were exposited.
