摘要:
 基于中国制、美国制和国际制3种不同土壤粒级分级方法对沙地樟子松林地土壤体积分形维数进行计算，以揭示不同粒径分级制度对樟子松林下土壤体积分形维数测定的影响，并探讨各粒径分级制度内在的联系。粒径组成及土壤体积分形维数分析、计算采用激光衍射技术方法进行测定。结果表明，1)樟子松林地土壤颗粒组成以砂粒为主，占总体积的75%左右、粉粒其次，占总体积的15%左右、粘粒含量相对较少，占总体积的3%左右；2)土壤体积分形维数排序为中国制(DCHN)>国际制(DINT)>美国制(DUS)；3)DCHN、DINT和DUS与土壤粘粒和砂粒含量呈显著相关(P<0.05)，但是与土壤粉粒含量相关性较差(P>0.05)；4)DCHN、DINT和DUS之间呈极显著正相关关系P<0.01)，且线性回归方程可实现三者之间的转化。综合分析3种土壤粒级分级方法均能有效反映土壤颗粒分布信息，且相较于DCHN和DINT，DUS与土壤颗粒含量的相关性较好，粒径范围较宽阔，D值差异较大，实用性较好，是计算樟子松林地土壤体积分形维数的较优选择。
Abstract:
 The objectives of this study were to probe the relationship among soil particle size classification systems (PSC) such as Chinese (DCHN),American (DUS) and International (DINT) and to reveal the effects of these three systems on the calculation of the volume-based fractal dimension of Mongolian pine plantations in Mu Us Desert.The soil particle size distribution (PSD) and volume-based fractal dimension (D) were measured with a laser diffraction technique.The results indicated that 1) the predominant soil particle size was distributed within the sand classification,which accounted for about 75% of the total volume,followed by silt particle (about 15%),and clay particle (about 3%).2) The order of volume-based fractal dimension was DCHN>DINT>and DUS.3) Significant Pearson correlations occurred among DCHN,DINT,DUS and clay,sand particle contents (P<0.05) respectively,while insignificant Pearson correlations occurred between DCHN,DINT,DUS and silt particle content (P>0.05).4) Highly significant and positive correlations were found among DCHN,DINT,and DUS.The linear regression analysis realized mutual transformation among these three PSC.Taking into consideration on the results above,three PSC could effectively reflect the information of soil particle distribution.Among the three PSC,DUS exhibited many advantages,such as good correlation with soil particle contents,wide range of particle size classification,large differences in D values,and good practicability,indicating that PSC system should be the optional system for calculating D of soil PSD of Mongolian pine plantations in Mu Us Desert.
