采用现场数据收集和定量分析的方法,从集材距离、集材时间和趟载量3个方面,对不同采伐方式下,落叶松人工林畜力集材的效率进行比较研究。结果表明:无论采用皆伐还是采用择伐生产方式,随着集材时间和集材距离的增加,集材效率均降低。在皆伐伐区,趟载量与集材效率的关系不明显;在择伐伐区,集材效率随着趟载量的增加而降低。对于平缓坡的落叶松人工林,皆伐伐区的畜力集材生产率要优于择伐伐区畜力集材生产率。
Using field data collection and quantitative analysis methods, the efficiencies of animal husbandry in Larix gmelini plantations were compared under different harvesting methods from the aspects of skidding distance, skidding time and loading capacity. The results show that, with either clear cutting or selective cutting method, the skidding efficiency decreases with the increase of skidding time and skidding distance. In the clear cutting area, there is no obvious relationship between the loading capacity and the efficiency of the skidding. In the selective cutting area, the skidding efficiency decreases with the increase of the loading capacity. For larch plantations with gentle slopes, the productivity of livestock skidding in the clear cutting area is better than that of the livestock skidding in the selective cutting area.
