%X Sustainable land use models are regional ecology and economy, it is especially prerequisites of sustainable development of true for arid land areas where environment is wholly fragile thanks to very limited precipitation and where human activities have greatly transformed natural desert system by clearing natural vegetation, expanding oases and even building dams. However, the up-to-data study of land use models is still in a stage of investigation and case study, lacking solid scientific basis. This paper holds that land types and their combination patterns are the principal basis for designing sustainable land use models, and that GIS and RS-based large-scale land type mapping and their spatial combination structure study should be coordinated with the demand of social development and carried out in the near future. The existing environmental problems induced by irrational land use mostly result from their deviation from the natural properties of land types. This paper, taking the northern Tianshan Mountains as an example and considering land type patterns as the basis of land use patterns, improves the vertical oasis and middle mountain two belt development model and mountain land use model for arid land put forward in recent years, and, in terms of oases patterns, outlines oasis development models, including diluvial-alluvial fan intensive land use model, alluvial plain moderate-scale agricultural development model, and river-end oasis ecological use model.
