摘　　要：皆伐作业通常采用油锯伐木,少数采用弯把锯。这是因为油锯的综合效益比弯把锯好。这里通过对两种伐木机具在人工林皆伐伐区中进行了三大效益综合评价和在天然林皆伐伐区中进行了经济效益分析,从而进一步证明了上述结论的科学性。Cutting by chain saw is used commonly and cutting by manpower saw is seldom used in operation of clear cutting. Through the comprehensive evaluation on the economic benefit, ecological benefit and social benefit of two kinds of cutting equipment in artificial forest clear cutting area and the analysis on economic benefit in natural forest clear cutting area, the result shows that the comprehensive benefit of chain saw is better than manpower saw.

关 键 词：皆伐 油锯 弯把锯 综合评价 选优
