Abstract：Using the index of building occupying land proportion and building construction proportion, the authors studied the characteristics and rules of the existing building constitution and their spatial distributions from districts, functional regions, looping areas around their functional group center scale to whole Lanzhou city via the data based on the highly precise Satellite Image and methods of massive fieldwork GIS technology and math statistics. In each functional and looping area of Lanzhou city, kinds of buildings are in fast renewing conditions. The buildings in each functional and looping area mostly industrial ones while the others are for living use. In 1970s, there was less difference in the percentage of these two kinds of buildings. It is evidential that the living building in Lanzhou has been predominant in all districts and all looping areas around their functional group centers except the looping area around Xigu group centers. Actually, the most parts of the older living buildings are the ones of "village inside city", the living, industrial and commercial buildings are leading types of Lanzhou's buildings, and the first one's proportion is increasingly going up everywhere while the second's decreasing, but their total proportion exceeds 92% of whole buildings, and the living building occupying land proportion and building construction proportion is 60% and 72.3% respectively. In addition, the others' proportion has also been enhancing slowly. Although all building types have been modernizing fast, the buildings in Xigu district are still older than those in other districts. In Chengguan-Qilihe districts the living buildings' proportion has a reducing trend. The buildings' distribution in Xigu and Anning is different from Chengguan-Qilihe's. From the view of functional district, the analysis shows that the temporal constitution of the buildings is mainly 1980s' and later. The old industrial districts' buildings are older than those of central districts and blending districts while the time constitution of the blending districts' buildings are newer than those in the central districts. The temporal constitution of Anning industrial districts' buildings are mainly like the central district buildings', but the old industrial districts' buildings are much more than the Central's. At last, the authors point out that the living lands have an intense concentration in the central and blending districts. The authors argue that the CBD function needs to be intensified. Unlike living lands' concentration, the distribution of the industrial districts is still very wide today.
