Landform-based pedodiversity of some soil chemical properties in Hainan Island,China
海南岛不同地形上某些土壤化学性质的多样性分析

Diversity indices and abundance distribution models are the statistical tools having been applied by ecologists for decades to analyze the intrinsic regularities of various ecological entities.In this work,similar techniques were used to analyze the pedodiversity of some soil chemical properties in Hainan Island,China,and discussions were conducted on the basis of related SOTER digital databases.Through the calculation of the richness (S),diversity (H') and evenness (E) of pH value,CEC and organic matter content in surface soil of different landforms and the establishment and application of the multi-distribution models of these soil chemical properties,the pedodiversity of some soil chemical properties of different landforms in Hainan Island in the GIS environment could be expressed digitally.
