摘 要:采用对比实验的方法,对小兴安岭林区主要森林类型采伐后土壤水分物理性质进行了测定和研究。结果表明:森林采伐后土壤容重增大,孔隙度减小,土壤持水性能降低。其中,皆伐比择伐对土壤的影响大,且集材道土壤的破坏也最大。采伐后选择适当树种及时人工造林,有利于土壤的保护和改善,采伐迹地的撩荒则使土壤破坏加剧。The physical property of soil water was measured and studied by comparative experimental method in the main forest types in Xiaoxing'an Mountains after harvesting. The results showed that forest harvesting resulted in increase in soil volume weight, lessening porosity, and decline in function of water holding. Clear-cutting did more serious damages to soil, compared with selective cutting. The most serious damage to soil occurred on the skidding path. Planting suitable tree species after harvesting contributes to soil conservation.
