摘  要：
通过对辽东山区不同间伐强度的蒙古栎林土壤物理性质和蓄水特性连续测定,结果表明:间伐11年后各试验区的0~10 cm和10~20 cm土层的土壤容重,间伐I区与间伐II区比对照区均有所减小,土层的总孔隙度和非毛管孔隙度均有所增加.间伐20年后各试验区土壤容重、总孔隙度、毛管孔隙度差异不显著(p>0.05).以间伐11年后林分的物理性质为参照,间伐20年后各试验区土壤的容重增加,总孔隙度和非毛管孔隙度均减小.抚育间伐可以改善森林土壤的物理性质,增加土壤的水源涵养功能,间伐II区效果最好,作用时间最长.

摘  要：
Soil physiological properties and water storage in Quercus mongolica forest were measured continuously after treated by different thinning intensities. The results indicated that: 11 years after thinning, soil volume weight of 0~10 cm and 10~20 cm of the I district and the II district was smaller than that of control, whereas the total porosity and non-capillary porosity was increased. 20 years after thinning, there were no significant differences among all treatments in soil volume weight, the total porosity and non-capillary porosity(p>0.05). Taking soil physiological properties in forest 11 years after thinning as reference, soil volume weight was increased, and the total porosity and non-capillary porosity were decreased in all treatments 20 years after thinning. Tending and thinning could improve the soil physiological property and water storage function. The II district showed the best effects and the longest action.
