Landform Based Pedodiversity of Some Soil Properties in Hainan
海南岛不同地形上土壤性质的多样性分析

Diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. In this work, similar techniques are used to analyze pedodiversity of some soil properties, and discussions are conducted on the basis of the SOTER digital databases in Hainan Island of China. Through calculation of indices of richness (S), indices of diversity (H') and indices of evenness (E) of soil profile depth types, soil horizon number types and soil (surface) bulk density types of different landforms, and establishment and application of the model of multi-distribution of soil profile depth types, soil horizon number types and soil (surface) bulk density types of the landforms, the analysis of pedodiversity of some soil properties of different landforms in Hainan under the GIS environment can be expressed digitally.
