| 摘 要： | 以黑龙江省带岭林业局落叶松人工林为试验点,采用4种不同的采集作业模式,应用层次分析法,综合考虑作业成本、作业效率、保留木损伤、土壤干扰以及木材损耗5个指标,定量计算平缓坡和陡坡条件下不同采集作业模式的综合效益.结果表明:择伐-畜力集材作业模式是该类型伐区最适宜的作业模式.

| Abstract: | Larch plantation is one of main commercial forests and has an important function to national economy construction. Four kinds of harvesting methods were done in larch plantation in Dailing Forestry Bureau, Heilongiiang Province. The paper calculated the comprehensive benefits of the four harvesting methods under the fiat and steep slopes, considering operation costs, operation effects, seedlings destruction, soil disturbance and wood wastes, by using analytic hierarchy process method. The result indicated that the selective cutting-animal skidding mode was the optimal harvesting method for the forest areas. |
