Abstract

Based on the calculation results of constituent diversity and spatial distribution diversity of soils and land uses in a typical region of northern Henan province, the new pedodiversity methodology was applied for exploring the intrinsic relationship of the geo-spatial distribution patterns between the regional soils and land use types. Our results showed that the soil constituent diversity of case area was 0.819 that means the soil composition in case area was more complicated. There was a certain connection between soil area and soil distribution diversity due to the soil types with the largest area and the highest spatial distribution diversity and the soil types with the smallest area and the lowest spatial distribution diversity have high overlap in various grid scales. Through the calculation and analysis of the correlation coefficient between 4 representative soils and land use types, it was found that the superposition relationship between soil and land use in case area became more complex over time.
