【摘要】 为适应我国森林非皆伐作业比重逐渐加大的变化要求,我们在塔河林业局用JC-30和J-50两种拖拉机、配置三种集材工艺方案,在非皆伐试验地进行了试验,考核其效率、成本、对保留木损伤等项目。结果表明:两台不同的机械完成集材任务的联合集材工艺方案是可行的。实施此方案,建议使用小功率的微型绞盘机替代JC-30,完成集材前段任务——小集中的工作,将会更经济。更多还原

【Abstract】 To adapt the change that un-clear cutting jobs gradully increase in our country, two kind of tractors JC-30 and J-50 with three industrial art plan of skidding were experimented on in Tahe Forestry Bureau. The efficiency, cost and injury to remaining trees were examined. It was shown that the industrial art plan of two different tractors accomplishing of the task of skidding is possible. When the plan is carried out it is better that micro-ground skidder complish the preceding task in stead of JC-30.更多还原
