摘要
定量分析农用车集材对马杉混交人工林迹地(集材道)土壤理化性质的影响,结果表明:集材后除土壤容重和结构体破坏率指标增大外,林地土壤其余指标均下降,而且表层土壤(0～20cm)所受影响较底层土壤(20～40cm)大;从森林生态采运角度出发,提出减少集材作业对林地土壤破坏的技术措施.
The effect of farm truck skidding on the physical and chemical properties of soil in artificial mixed forest of Pinus massoniana and Cunninghamia lanceolata was analyzed quantitatively.The results show the other indexes of physical and chemical properties of soil decline except the volume weight of soil and the damage rate of soil structure increasing,and the surface soil(0～(20 cm))are impacted more seriously than the bottom soil(20～40 cm).Some technological measures for reducing the damage of soil were put forward for the ecological harvesting operation.
