摘　　要：通过对半悬索道集材后林地土壤理化性质的分析，结果表明：半悬索道集材后土壤容重增加，土壤结构和水分性能变差，土壤养分含量下降。集材对林地土壤的扰动以主沟处最为严重，主沟外则较轻微。在此基础上提出减少该类型集材作业对林地土壤破坏的建议。The results showed that after skidding operation,the soil density increased,the soil moisture condition got bad, the soil porosity and the contents of soil nutrients decreased. The soil in the major timber hauling area under the skyline was disturbed to some extent, beyond which it changed slightly.In the basis the analysis,the corresponding countermeasures of reducing the damage of soil for forest harvesting were put forward.

关 键 词：半悬索道 集材索道 土物理性质 土壤肥力
