Temperature, as a kind of agriculture resource, is formed by solar radiation to atmosphere, its distribution on earth surface is interwoven with topographic characteristics of the surface, especially in mountain area. Digital Elevation Model (DEM), as a descriptive way of the surface pattern, has practical value in all kinds of monographic study and planning decision using spatial information. In this paper, Topography_ Adjusted Statistical Model (TASM), which corrects the mountain temperature based Conventional Statistical Model (CSM) by using the topographic factors (slope and aspect) on the small scale, was presented, and applied in the region around Qinghai lake. The results show that TASM is superior to CSM and provides a method of temperature simulating spatially in mountain area, and has important significance to thematic application concerning temperature resource in mountain area.
