%X Satellite images acquired in 1984, 1991, 2000 and 2005, respectively, were used to interpret the boundaries of cities and towns in the south of Jiangsu province along the Yangtze River on the basis of our boundary definition. And then regional urban spatial sprawl pattern was uncovered quantificationally by some indexes, such as fractal dimensions including radius dimension, grid dimension, correlation dimension, boundary dimension, compactness index, and spatial autocorrelation index including global Moran I and local Moran I. The result shows that:(1) fractal dimension metrics and spatial autocorrelation index, respectively, can quantificationally reveal regional urban spatial distribution features and spatial sprawl process and cluster pattern, and their fuse can measure regional urban spatial sprawl pattern and uncover the process of how to form the urban cluster;and (2) at the initial stage of reform and open-up policy, the urban sprawl in the south of Jiangsu province along the Yangtze River was spontaneously point-pattern centered around big cities, and then point-axis-pattern dominated by policy-driven urban spatial fuse and fill, at present cluster-stretched pattern based on regional industry spatial organization driven by economical radiation and contact, and a big urban group is coming into being. Especially since 2000, spatial structure features of an urban group are more and more evident with time elapsing. Additionally, the main feature of urbanization in the study area is that industrialization pushes urbanization based on the background of global economy. In the study area three centric cities have existed since the 1980s, however, their spatial polarizations have a less and less effect on others.
