摘要
定量分析了皆伐作业土滑道集材对山地人工杉木林迹地土壤理化性质的影响,结果表明:土滑道集材后土壤密度增大,土壤结构和持水性能变差,土壤养分含量下降,且表层土壤(0～20cm)所受影响较底层土壤(20～40cm)大。为此从森林生态采运角度出发,提出了减少集材作业对林地土壤破坏的技术措施。
The effect of dirt chute skidding on the physical and chemical properties of trail soil of artificial Chinese fir forest was analyzed quantitatively.The results show that the unit weight of soil increases,the structure and the property of keeping water of soil decline,the content of soil nutrient decreases,and the surface soil(0～20 cm)is 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.
