Abstract: To study the spatiotemporal variation characteristics of urban architecture landscape is of significance in the reasonable adjustment of urban planning. In this paper, the buildings’ three-dimension information of Tiexi District, Shenyang was extracted by using Barista software and GIS and RS techniques, and the spatiotemporal variation characteristics and related affecting factors of architecture landscape in the district were analyzed with the indices of build-up area ratio, average building height, building coverage ratio, building shape index, and spatial center of gravity transfer model. From 1997 to 2008, the build-up area for resident and commerce in the district increased, while that for industry decreased. The buildings’ shape became more regular, building coverage ratio decreased, and buildings were growing in vertical direction. Spatially, the centroid of the architecture landscape change shifted from residential area to industrial estate, and then, from the center to the outskirts of the district. Economic development and population growth had positive correlations with average building height, and negative correlation with building density. The implement of urban renewal policy had significant effects on the variation of the architecture landscape. With the increasing distance from roads, the average building height decreased and the building coverage ratio decreased after an initial increase.
