摘 要: | 定量分析手扶拖拉机集材对人工杉木林迹地(集材道)土壤理化性质的影响,结果表明:除土壤容重和结构体破坏率指标增大外,其余指标均下降,且表层土壤(0~20cm)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.

Study on the Impact on the Trail Soil of Artificial Forest by Walking Tractor Skidding |
| |
Abstract: | The effect of walking tractor skidding on the physical and chemical properties of trail soil of artificial China fir forest was analyzed quantitatively The results show the other indexes of physical and chemical properties of trail soil decline except the unit 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 of reducing the damage of soil were put forward for the ecological harvesting operation |
