| 摘 要： | 落叶松人工林是我国北方林区主要用材林之一,对我国的国民经济建设起到重要作用.以黑龙江省带岭林业局落叶松人工林为试点,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、土壤干扰以及木材消耗5个指标,定量地计算了平缓坡和陡坡条件下不同采集作业模式的综合效益.计算结果表明,择伐—畜力集材作业模式是该类型伐区的最适宜作业模式.

| Abstract: | Larch plantation is one of the main commercial forests in north China and has an important contribution to the national economy. Four harvesting models were carried out in the larch plantations in Dailing Forestry Bureau, Heilongjiang Province. The paper calculated the comprehensive benefit of the four harvesting models under the flat and steep slopes, considering operation costs, operation effects, seedling destruction, soil disturbance and wood consumed, using analytic hierarchy process method. The results indicate that the selective cutting plus animal skidding model is the optimal one for the forest areas. |
