怀化市不同母质发育土壤在中国土壤系统分类的归属
Attribution of Soils Developed from Different Parent Materials in Huaihua City in Chinese Soil Taxonomy
摘要
Abstract
To clarify the attribution of typical soils in Huaihua City,Hunan Province under the Chinese Soil Taxonomy,this study selected twenty-one soil profile samples developed from seven types of parent materials in Huaihua City to analyze the soil-forming environment,profile morphological characteristics,and soil physicochemical properties based on field observations and laboratory analysis results.According to the Chinese Soil Taxonomy(CST)scheme,diagnostic horizons and characteristics were retrieved to determine the affiliation of soil samples in the CST.The results showed that the tested soil had anthraquic epipedon and hydragric horizon as its main diagnostic horizons.The soil profile exhibited prominent redox features,representing typical profile characteristics of Anthraquic-Anthrosols.Twenty-one soil profiles belonged to five soil orders including Ferrosols,Anthrosols,and Argosols,six suborders including Udic Ferrosols and Stagnic Anthrosols,eleven soil groups including Hapli-Udic Ferrosols and Fe-accumuli-Stagnic Anthrosols,fifteen subcategories including Typic Hapli-Udic Ferrosols and Typic Fe-accumuli-Stagnic Anthrosols,seventeen soil families,and twenty-one soil series.关键词
