| 摘 要： | 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

| Abstract: | Forest harvesting slash disposal is one of the important parts of forest operations. A field survey for investigating slash disposal was carried out in a forest sector in Heilongjiang Province, northeast China. Through the research, it is explicit that slash disposal has also affected on the physical and chemical properties of soil on the harvested sites. The presented results of this study show that both of piling method and burning method do not affect the physical properties of soil very much, but impact the chemical properties of soil quite significantly, and the burning method may cause soil erosion if handling poorly. |
