摘　　要：定量分析手板车集材对杉木人工林林地(集材道)土壤理化性质的影响,结果表明:除土壤密度和结构体破坏率指标增大外,林地土壤其余指标均下降,且表层土壤(0～20 cm)所受影响较底层土壤(20～40 cm)大;从生态采运角度出发提出减少手板车集材作业对林地土壤破坏的技术措施.The effect of push cart skidding on the physical and chemical properties of trail soil in artificial forest of Cunninghamia lanceolata was analyzed quantitatively. The results showed that the other indexes of physical and chemical properties of trail soil declined except the volume weight of soil and the damage rate of soil structure, and the surface soil (0～20cm) were impacted more seriously than the bottom soil (20～40cm). Some technical measures for reducing the damage of push cart skidding on the soil were put forward from the view of ecological harvesting operation.
