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。
Zhaoling Forestry Bureau in Xiaoxing’anling forestry area experimented on the frequency of woodlands by using the tractor of skidding tractor and crawler skid tractor to study its effect on the physical characteristics of forest soil. The results show that the index of physical characteristics such as soil subsidence, soil bulk density, soil saturated water holding capacity and soil porosity changes rapidly when the passing times of vehicles are between 1 and 7 times; After the second change, the change is insignificant. From the perspective of the effect of skidding vehicles on forest land, the effect of crawler vehicles on forest land is less than that of wheeled vehicles. It is suggested that crawler-powered operating equipment be preferentially selected under the same operating conditions.
