【摘要】：选取河南省10个典型含有人工制品的土壤剖面和3个自然土壤剖面作为研究对象,基于剖面形态和理化性质的分析,根据世界土壤资源参比基础(WRB)、美国土壤系统分类(ST)、中国土壤系统分类(CST),对供试土壤进行分类研究。结果表明,WRB中关于人工扰动的前缀修饰词或后缀修饰词不能完全适宜于中国地区的含有人工制品的土壤,而在ST中,含有人工制品的土壤类型出现在各个土纲及其包含的亚类单元,CST中缺乏明确的诊断依据来描述、解释含有人工制品的土壤特征。参照WRB和ST中关于人工制品类别相关标准,提出CST中含有人工制品的土壤定义,新增"技术扰动层"诊断特性,制定CST人工制品类别标准,并将这一标准体现在CST土族命名中,该分类方案能有效体现不同人为活动对土壤的影响结果,一定程度上填补我国对这类土壤分类研究的空白。
[Abstract]:Ten typical soil sections containing artificial products and three natural soil sections in Henan Province were selected as the research objects. The morphological and physical and chemical properties of the sections were analyzed. According to the World soil Resources reference basis (WRBB), the United States soil system Classification (STS), and the Chinese soil system Classification (CSTS), the study on the soil taxonomy of the tested soils was carried out. The results showed that the prefix modifiers or suffix modifiers on artificial disturbances in WRB could not be finished. All suitable for the soil containing artificial products in China, However, in St, the soil types containing artificial products appear in various soil classes and their subclass units CST without clear diagnostic basis to describe them. According to the related standards of WRB and St about artificial products, the soil definition of artificial products in CST is put forward, and the diagnostic characteristics of "technical disturbance layer" are added, and the classification standard of CST artificial products is established. This standard is embodied in the CST Tu nomenclature. This classification scheme can effectively reflect the effect of different human activities on soil, and to a certain extent fill the blank in the study of this kind of soil classification in China.
