Formation Characteristics and Taxonomy of Soils in Baise Youjiang River Valley in Guangxi
摘要
Abstract
[ Objective] To attempt to define the soil in Baise Youjiang river valley in Guangxi according to the Chinese Soil Taxonomy. [ Method] The physical and chemical properties of soils of six soil profiles in different elevation and parent material types collected from the river valley were studied. Based on the Chinese Soil Taxonomy (3rd edition) , the diagnostic horizons and diagnostic characteristics of the soil profiles as well as related taxonomic classification category were also defined. [ Result] There were the eluviation and ferrugination in the soil. In the soils of horizons of the soil profiles developed from the quaternary red clay and gritstone, the soil pH and base-saturation percentage were low, while those in the soils developed from tertiary period mudstone and limestone were high. Moreover, the contents of free iron oxide were over than 45. 2%. The Sa values of B horizons in the soil profiles were 2.08 -2.69. [ Conclusion] There was one subgroups including one orders in Baise Youjiang river valley in the present study.关键词
