提出了青藏高原土壤区划的原则和土壤区划单位（土壤地带－土区）系统及新的区划方案，并简述了各土壤地带与代表性土区的成土环境特点、土地利用方向及代表性的山地土壤垂直带谱。

SOIL REGIONALIZATION OF THE QINGHAI-XIZANG PLATEAU

According to relative types and its regional differentiation of compo-pattern of vertical soilbelts in the mountains and the asricultural resional types, 10 soil zones and 29 soil resions weredivided in the Qinghai-Xizang Plateau.Two ciass units in the soil regionalization system are divided according as followings :1. Soil zone based on the horizontal differentiation of hydrothermal condition and rela-tive types of compo-pattern of vertical soil belts in mountains. It's named as the administrativediviston or the geographic region and the representative soil great groups.2. Soil region bated on the regional differences of compo-pattern group of vertical soilbelts in mountains within the soil zone. It's named as the landform and the representative soilgreat groups.Finally, the geosraphic distribution, soil forming environment, main soil types and theirvertical structure,and developing direction of regional agriculture for 10 soil zones and represen-tative soil regions are summarized.
