摘　　要：基于多样性理论对山东省不同母岩发育的土壤类别空间可变性及其分布格局进行了研究,数据源是山东省1:100万SOTER数据库.研究包括土壤多样性分析(丰富度指数、多样性指数和均匀度指数的计算和分析).根据统计运算结果建立土壤类型多度分布模型,发现不同母岩上发育的土壤都符合对数正态分布,即系统中符合中间多度的对象最为普遍,并应用于分布格局的解释中.最后在GIS环境中实现不同母岩上发育的土壤类别空间可变性的数字化表达.This paper applied pedodiversity analytical theory and method to analyze the Spatial Variability of the Soils developed on different parent materials..The data source is 1:1,000,000 scale soil and terrain digital database (SOTER) of Shandong Province. Richness index, evenness index and diversity index were selected as indicators of Pedodiversity. The distributions of soil groups relative abundance developed on different parent materials were set up on the basis of statistical and calculated results, found it matches the logarithmic normal distribution where soils with intermediate abundance are most common. Moreover they are applied to explain soils distributions. Lastly, geography information system (GIS) mapping to show Spatial Variability of the Soils digitally developed on different parent materials.
