中文摘要	以我国祁连山和河西走廊西段的土壤为研究对象,应用遥感资料以及野外实地调查取样的方法,将研究区的土壤母质划分为残积、坡积、洪积、冲积、红土、冰渍、湖积7类;该区土壤的分布具有明显的垂直地带性和经向分布规律,土壤类型从祁连山区到酒泉盆地形成高山寒漠土、高山草甸土、亚高山草甸土、栗钙土、亚高山草原土、风沙土、棕漠土、潮土、灌漠土、盐土、沼泽土等13个土类和32个亚土类,并研究了不同土壤类型的空间分布规律及基本特征;结合该区土地利用的现状,提出了该区土地适宜性评价的原则和方法,将该区土地适宜性划分为宜农、宜林和宜牧3种类型;对不同适宜性土地的等级及分布等特征进行了评价,并对该区土地资源特征以及存在的问题进行了探讨.
英文摘要	Formation and distribution of regional soils are affected and controlled by topography, climate, mother rocks, vegetation, frozen earth, moisture conditions, etc. In this paper, the western segments of the Qilian Mountain and the Hexi Corridor are selected as the study areas to research the characteristics of soils and land suitability. By applying the methods of remote sensing and comhining the field investigation, the soil parent material in these areas is divided into 7 types, i. e., the eluvium, slope wash, diluvial deposits, diluvial deposits, laterite, moraine deposits and lacustrine deposits. There is a remarkable vertical and longitudinal zonal distribution of soils. From the Qilian Mountain to the Jiuquan Basin, the soils can be divided into 13 soil types and 32 sub-types, the former includes the alpine Ramork, alpine meadow soil, subalpine meadow soil, chestnut soil, subalpine steppe soil, aeolian sand soil, brown desert soil, damp soil, irrigated desert soil, salty soil and swamp soil, etc. The spatial distribution laws and the basic characteristics of the different soil types are researched. Considering from the actuality of land use in these areas, the principles and methods of evaluating the land suitability in these areas are put forward, the land suitability is divided into 3 types, i.e., the lands suitable for farming, afforesting and developing animal husbandry. The grades and distribution of the land suitability are evaluated, and the land resources and the existing problems are also discussed.
