土壤区划类型的参比与属地化研究

文章以详细的1981年土壤分区资料为基础,将以发生分类(GSCC)为基础的土壤类型名称分别参比成中国土壤系统分类(CST)名称和美国土壤系统分类(ST)名称。同时利用G IS空间分析技术,确定了中国8个土壤大区在地级市(盟)和各县、区、旗(市)的行政归属,并以江南低山丘陵和台湾北部地区为例,探讨了二级分区的行政归属。

Soil Type Reference and Administrative Area for Soil Regionalization in China

In the past,soil type names involved in soil regionalization programs in China were those adopted by internationally unknown and imcomparable Genetic Soil Classification of China(GSCC) system.Consequently,both soil names and soil regions concerned in such regionalization programs were not good for scientific exchange and comparison in the world,even in China itself.Besides,lack of adequate correlation between soil regions delineated in such regionalization programs and administrative zones resulted in difficulties for application of soil profile data and soil region data.In this paper,soil names adopted in GSCC are converted into those adopted in Chinese Soil Taxonomy(CST) and US Soil Taxonomy(ST) respectively on the basis of detail soil region data in 1981 regionalization program and soil name reference system.At the same time,with the aid of GIS,the correlation between 8 great soil regions in 1981 regionalization program and their corresponding administrative areas at both prefecture and county levels are determined,and for more detail case study,the correlation between the soil region of low-mountain-hilly south of the Changjiang River as well as northern Taiwan in the same program and their corresponding administrative areas is also discussed.
