摘要
在小兴安岭林区的带岭林业局对轮式集材拖拉机和履带式集材拖拉机通过林地次数进行了实验，以研究其对林地土壤物理特性的影响。结果表明：车辆通过次数在１～７次时，土壤下陷量、土壤容重、土壤饱和持水量和土壤孔隙度等各项物理特性指标变化较快；在８～１５次时变化较平缓；在１６次后，变化不显著，从集材车辆对林地作用程度看，履带式车辆对林地作用程度比轮式车辆作用程度小，建议在相同作业条件下，优先选择履带式作业设备。
The
effects of passing trips of skidding vehicles, tyred skidder and tracked crawler, on the physical
properties of soil in the cutting sites was determined on Dailing Forestry Bureau in Xiaoxing′
anling forest region. The result showed that the physical parameters such as weight by volume.
saturated water capacity and porosity of soil changed sharply when the passing trips are less
than 7, and they changed smoothly when the passing trips are within 8～15, and change weakly
when larger than 16. From the point of view of vehicle damage onto forest soil, the tracked
crawler is better than the tyred skidder due to its light impact to soil.
