| 摘 要： | 研究了油松纯林与油松蒙古栎混交林的物理性质及其变化规律.结果表明,土壤物理性质随林型和土壤深度变化的差异极显著.在0～30 cm土层中,混交林的土壤容重比纯林低0.006～0.052 g/cm3,总孔隙度提高了-1.668%～1.838%,最大持水量提高了-2.672%～17.555%.表明油松蒙古栎混交林对改良土壤物理性质、提高土壤贮水保水能力均较油松纯林具有显著作用.

| Abstract: | The physical properties soil planted with pure Pinus tabulaeformis and the mixed-stands of Pinus tabulaeformis and Mongolian oak were studied.The result was as follows:the bulk density varied dramatically with the type of stand and soil depth.Compared with Pinus tabulaeformis planting,the mixed stand of Pinus tabulaeformis and Mongolian oak could reduce soil bulk density through the function of litters and root system,and to some degree,improve soil prosity and raise soil moisture capacity.Total prosity and max moisture capacity were raised to by-1.668%～1.838% and-2.672%～17.555%,respectively.These findings showed that it was favorable to improve soil hydro-physical properties through the building of mixed-stand of Pinus tabulaeformis and Mongolian oak. |
