Abstract: To study the factors affecting the changes of three-dimensional urban architectural landscape is of guiding significance for the rational distribution and adjustment of future urban landscape. By using buffer belt analysis method, this paper studied the influence of location factors on the changes of three-dimensional architectural landscape in Tiexi District of Shenyang from 1997 to 2008. In the District, the closer to the main roads, the higher the average building height; the closer to the locus of the government, the higher the building coverage ratio and floor area ratio but the lower the building energy consumption; and the closer to the commercial center, the higher the average building height and floor area ratio. Garden and commercial center had minor influence on the urban landscape change.
