摘要: |
选择我国北亚热带地区归属湿润淋溶的22个土壤剖面为研究对象,研究了中国土壤系统分类中土族的划分依据和指标,指出,土族的划分应以土壤本身的性质为依据,反映土壤理化性质并影响土壤利用管理的颗粒大小级别,矿物学类型和土壤温度级别是理想的土族分类标准;土族命名要以这些属性名称加在名称连续命名,以准确地反映土壤的性质和分类地位。 |

Abstract: |
This paper illustrates the result of studies on 22 soil profiles which distributed in the North-subtropical region. These soil samples belong to Udic Luvisol according to Chinese Soil Taxonomic Classification. Three soil characteristics are selected as family classification criteria. They are particle-size class, soil mineralogical type and soil temperature regime. The 22 soil profiles fall into 18 families, 8 subgroups and 5 great groups. |
