Discussion on the Comparison with the Classification of Soil Genesis,Taxonomy and the Pedogenesis of Cinnamon Soils in Beijing
The study determined and contrasted the belongs of the profiles in Genesis and Taxonomy Classification respectively,and discussed its forming process by taking 10 cinnamon soils profiles which were distributed in the mountainous and piedmont area of Beijing as the research object,basing on the analysis of the morphological characteristics,physical and chemical properties and according to Beijing soil,Keys to Chinese Soil Taxonomy (3rd ed),and Criteria for establishment of soil family and soil series in Chinese Soil Taxonomy.Its results show that the Soil Genesis Classification occurred mainly by treating soil biological (vegetation) climatic zone as classification criteria,and the results in the confusion of the classification easily lead the genetic theory to put too much emphasis on the external conditions of soil-forming and the speculation process.Chinese Soil Taxonomy guided by the genetic theory improves the accuracy of classification through quantitative diagnostic horizons and diagnostic characteristics.
