摘　　要：以福建省三明市将乐国有林场内的杉木林作为研究对象，采用环刀法对皆伐与不同迹地清理方式下杉木林的土壤物理性质进行研究，旨在为杉木林的科学经营提供理论依据。结果表明：不同深度土层中，皆伐后1、3月的土壤容重均高于皆伐前；随着皆伐后时间的推移，同一土层中的毛管孔隙度、非毛管孔隙度、土壤含水率和总孔隙度呈现逐渐递减的趋势。同一土层中（除0～5 cm），不同迹地清理方式下样地的土壤容重存在显著差异，其中，采用炼山清理后的迹地土壤容重明显高于采用带状整地清理的迹地；不同深度土层中，对于土壤的毛管孔隙度、非毛管孔隙度和土壤含水率等土壤水分物理性质，炼山处理后的结果均低于带状整地方式。By taking the state-owned forest farms of Cunninghamia lanceolata forest in Sanming City, Fujian Province as the researched object, adopted the ring knife method under different mark place clean up the way of clear cutting and Cunninghamia lanceolata forest soil physical properties were studied, aimed to provide theoretical basis for the Cunninghamia lanceolata forest scientiifc management. The results showed that the soil of different depth, soil bulk density of 1,3 months after clear cutting were higher than before clear cutting;with the passage of time after clear cutting, the same soil capillary porosity and non-capillary porosity, soil moisture content and total porosity showed a gradual decreasing trend. In the same soil （except for the 0~5 cm）, under the different way to be clean up sample soil bulk density of signiifcant differences, which, using controlled burning cleaned soil bulk density was signiifcantly higher than the use of clean-banded site preparation; soil at different depths, for capillary porosity of the soil, soil moisture non-capillary porosity and other physical properties of soil moisture, affect the outcome of treatment after controlled burning land preparation methods were below the ribbon.
