Abstract:: RS technique was used to quickly and accurately obtain and monitor urban land-use information, which is helpful to rationally plan city and protect ecological environment. Chongqing Main City Zone Normalized Differences Built-up Index (NDBI) was extracted through the data sources including 2002, 2007, 2010 Landsat TM remote sensing data, and the quantitative structure and spatial distribution characteristic of Chongqing Main City Zone NDBI were obtained.The NDBI of fractal dimension and stability were studied based on fractal theory. The results indicated that the low building district was decreased and the high building district was increased from 2002 to 2010. With respect to spatial distribution, Banan district built-up index is lower than other districts obviously, Jiulongpo district and Yubei district built-up index are relatively high. The low building district of the patches’ complexity is higher than the high building district, and the high building district of stability is higher than the low building district. It is mainly because that the construction land is relatively concentrated, and patch shape is more regular, little in external interference. The results offer reference for urban land utilization and management and the city ecology protection of Chongqing.
