采伐剩余物迹地清理是森林作业的重要组成部分之一。本文通过在黑龙江省带岭林业局野外迹地取样和实验室分析 ,对森林采伐剩余物迹地清理方式对迹地土壤的影响进行了初步研究。结果表明 ,迹地清理方式对作业迹地土壤理化特性产生一定程度的影响 ,进而影响森林采伐后的迹地天然更新与苗木生长质量。研究结果还表明 ,火烧和堆积方法对迹地土壤物理特性影响不十分显著 ,但对土壤的化学特性影响十分显著 ,尤其是火烧迹地土壤养分流失程度差异比较显著
The clearance of logging remains is an important part of forest operations. In this paper, through field sampling in Heilongjiang Province with forestry bureau and laboratory analysis, the impact of clearing ways of residual forest landings on the soil was studied. The results showed that the way of land clearing affected the soil physical and chemical properties of the land track to a certain extent, and then affected the natural regeneration of the land after logging and the quality of seedling growth. The results also show that the fire and accumulation methods have little effect on the physical characteristics of the soils, but have significant effects on the chemical characteristics of the soils. In particular, the difference of soil nutrient loss in the burned areas is significant
