Diversity of Anthrosols in China
摘要
Human activities make strong effects on soil formation.Anthropogenic soils are much more intensive and extensive in China for their history of agricultural production can be dated back to more than 7000 years ago Owing to different physical conditions and land uses,the anthropogenic soil-forming processes are various Anthrosols are proposed,and the corresponding soil order is set up in Chinese Soil Taxonomy(CST),Mainly based on 6 Anthropogenic diagnostic horizons,which are anthraquic epipedon,hydragric horizon,irragric epipedon,cumulic epipedon,fimic epipedon and agric horzon,the Anthrosols Order is subivided into 2 soil suborders and 4 soil groups.Meanwhile the classification of Anthrosols in CST has been basically accepted as the classification of Anthrosols in World Reference Base for Soil Resources(WRB).
