中文摘要	对比研究毛乌素沙地南缘不同密度樟子松人工林林下各土层(0 ~ 10cm,10 ~ 30cm,30 ~ 60cm)土壤理化性质差异及与林分生长关系。结果表明:自然化培育下的人工林林地土壤物理性质: P_(Ⅶ)和P_(Ⅷ)样地总孔隙度和毛管孔隙度较高,持水能力较强且与其它样地差异明显。土壤化学性质: P_(Ⅷ)和P_(Ⅺ)样地各层土壤的全N、P含量、水解性N、有效P含量较高且与其它样地差异明显;全K含量和pH值在各样地土层无明显差别;有机质方面,上层土壤有机质含量P_Ⅰ,P_(Ⅳ),P_(Ⅵ),P_(Ⅷ),PⅩ,P_(Ⅺ)样地含量高于其它样地。结合频度分布和Pearson分析结果,土壤化学物质对林分生长如树高、胸径有较好的支撑作用。综合考虑P_(Ⅷ)样地林地密度为较为合适的造林密度,可以更好地发挥其半干旱地区的生态效益。
英文摘要	This research aimed to evaluate soil physicochemical properties in soil depth (0 ~ 10cm,10 ~ 30cm and 30 ~ 60cm) and their relations with stand growth traits under different densities of Mongolian pine plantation in Southern Mu Us desert. The results showed that higher total porosity,capillary porosity and stronger water holding capacity were found in P_(Ⅷ) and P_(Ⅶ). While there were obvious differences in water holding capacity among all plots. All soil depths of P_(Ⅷ) and P_(Ⅺ) were found higher in total N,P,hydrolysable N and available P,and had significant differences compared to other plots. But no differences were found in total K and pH values among all plots. There were higher concentration of organic matter in P_Ⅰ,P_(Ⅳ),P_(Ⅵ),P_(Ⅷ),PⅩ and P_(Ⅺ). Frequency analysis and Pearson analysis results showed that most of chemicals had good supporting effect on stand growth such as tree height,diameter at breast height. Considering above,for suitable planting density,P_(Ⅷ) was better to play its ecological benefit of water conservation.
