摘　　要：为了确定新疆和田开发区的土壤系统分类归属,对该区约220 km2待开垦土地进行了调查,分析了不同类型土壤剖面的理化性状,并对其诊断层和诊断特性进行了鉴定。结果表明,该地区棕漠土、风沙土、草甸土、盐土(按土壤发生学分类)在中国土壤系统分类中分别为普通石膏正常干旱土、弱盐干旱砂质新成土、普通简育干旱雏形土和普通干旱正常盐成土,最后对各土类提出了相应的利用措施。This study aimed to determine soil position in Chinse Soil Taxonomy through examining the physical and chemical properties of the different typical soil profiles in 220 km^2 land of Hetian Development Zone,Xinjiang. Diagnostic layer and diagnostic characteristics were identified according to Chinese Soil Taxonomy （3rd edition）. Results showed that local brown desert soils,aeolian soils,meadow soils,and sa- line soils, （GSCC） should be characterized as Typic Gypsi-Orthic Aridosols, Parasalic Aridi-Sandic Pri- mosols,Typci Hapli-Aridic Cambosols and Typic Aridi-Orthic Halosols in Chinese Soil Taxonomy and the corresponding measures were raised thereafter.
