摘要
对南岔林业局兴安落叶松人工林的不同年龄采伐和更新的调查资料进行分析得出:对于人工落叶松近熟林,在其采伐后更新树种的选择上应以云杉、红松为主,不宜选择落叶松造林;在采伐方式上,对落叶松人工近熟林的经营宜采用大强度间伐,每公顷保留400株为宜,不宜采用大面积皆伐和带状皆伐方式;落叶松人工林经济成熟年龄应定15～20 a;在一般公益林区,落叶松人工林数量成熟年龄应定在25-30 a为宜。
An experiment was conducted to investigate the regeneration effects of larch （ Larix gmelinii） plantations in Nancha Forestry BtLreau, Heilongjiang Province under different cutting styles. The investigation data of logging and regeneration of Larix gmelinii plantations of different ages showed that Picea asperata and Pinus koraiensis should be selected as the main regeneration species after the nearly mature larch plantations were clear cut, and larch is unsuitable to be replanted. High-intensity thinning, reserving 400 individuals per hectare, should be applied to the management of nearly mature larch plantations, while large scale logging and strip clear-cutting are inapplicable. The economic mature age of larch plantation should be fixed as 15 -20 years, and the quantitative mature age should be 25 - 30 years in general commonweal forest regions.
