Jiangsu province is a typical area of the urban extension problems. Urban construction land has been the major area of city research. And more and more people pay attention to this matter. In this paper, regional differences of urban construction land in Jiangsu province, China were analyzed. Firstly, this work is based on remote sensing images as the main data source in 2010. The spectral differences of soil cover type of waters, forest land, construction land, unused land, cultivated land were explored. Secondly, three kinds of index methods (soil adjusted vegetation index, modified normalized difference water index and the ratio resident-area index) were used to extract the information of urban construction land. Finally, urban construction land was segmented by administrative boundary information of Jiangsu Province, China. And, different areas of the urban construction land, non-urban construction land and cultivated land were compared and analyzed. The experimental results from the urban construction scale show that, in 2010, the south of Jiangsu is greater than the north of Jiangsu, and the north of Jiangsu is greater than the central of Jiangsu. From the point of proportion of cultivated land: the central of Jiangsu is greater than the north of Jiangsu, and the north of Jiangsu is greater than the south of Jiangsu.
