北京百花山地区土系鉴定及其在不同土壤分类体系中的分类与制图参比

The Series Identification and Classification and Mapping References Based on Different Classification Systems for Soils in Baihuashan, Beijing Region

根据中国土壤系统分类的原则和方法 ,将北京百花山地区的 16个土壤剖面分类为 10个土系 ,并将这 16个土壤剖面分别按中国土壤系统分类与地理发生土壤分类系统进行分类参比 ,结果表明 ,土系与土种单元在性质上基本一致 ,以它们为基础进行大比例尺调查制图所得图斑也必然相似 ;而在土系与土种以上的分类阶层 ,因为所使用的分类标准不同 ,两个分类系统划分的分类单元和据此进行的制图图斑则不一样 ;以土类为基础进行小比例尺制图 ,使用中国土壤系统分类只能复区制图 。

Sixteen soil profiles are divided into ten series by using the Chinese Soil Taxonomy in Baihuashan Region, Beijing. Classification and Mapping References are made based on different soil classification systems. It illustrates that the taxa and map polygons are same at lowest category whether using Chinese Soil Taxonomy or geographically genetic classification system; the taxa and map polygons are different at higher category using Chinese Soil Taxonomy and geographically genetic classification system. At group level, soil map will show complex element delineation using Chinese Soil Taxonomy; and will show single element delineation using geographically genetic classification system.
