在山东省1∶100万SOTER数据库的支持下,运用土壤多样性理论及其测度方法对山东省不同地形单元上发育的土壤类型的多样性及其分布模式进行了初步的分析和定量化的研究。结果表明:土壤多样性指数从大到小依次为平原、中坡度、中坡度丘陵、山麓平原、中坡度峭壁带、低洼地和高坡度山地;土壤丰富度指数从高到低依次为平原、中坡度丘陵、中坡度、低洼地和山麓平原、中坡度峭壁带和高坡度山地;土壤均匀度指数从大到小依次为:中坡度、平原、山麓平原、中坡度丘陵、中坡度峭壁带、低洼地和高坡度山地。不同类型地形单元上发育的土壤的面积均不同程度地符合对数正态分布。
With the support of the 1: 1 million SOTER database in Shandong Province, the diversity and distribution patterns of soil types developed on different topographic units in Shandong Province were analyzed and quantified using the theory of soil diversity and its measurement methods . The results showed that the index of soil diversity descends from plain to medium in order of plain, middle slope, middle slope, foothill plain, middle gradient cliff, low depression and high gradient. The soil richness index descends from plain to low Slope slope, mid-slope, low-lying land and foothill plain, mid-slope cliff belt and high gradient mountainous area. The soil evenness index descending order is as follows: middle slope, plain, foothill plain, middle slope slope, mid slope slope cliff zone, Ground and high grade mountain. The area of soils developed on different types of terrain units are logarithmic normal distribution to varying degrees.
