Choosing Xinzhuang Town in south Jiangsu Province as study area, and by using 1980, 1991, 2001, and 2009 high-resolution remote sensing images and GIS spatial analysis technology, an integrated expansion degree index model was established based on the existing indicators of construction land expansion, and the general and spatiotemporal differentiation characteristics of construction land expansion in the Town in three time periods of 1980-2009 were quantitatively analyzed. In 1980-2009, with the acceleration of rural urbanization and industrialization, the area of construction land in the Town increased significantly by 19.24 km2, and especially in 2001-2009, the expanded area, expanded contribution rate, and expansion intensity reached the maximum. The construction land expansion had an obvious spatial differentiation characteristic. In 1980-1991, the newly increased construction land mainly concentrated in town area. After 1991, the focus of construction land gradually spread to the villages with developed industries. Most of the increased construction lands were converted from paddy field and dry land, accounting for 88.1% of the total increased area, while the contribution from other land types was relatively small.
选取江苏省南部的新庄镇作为研究区域，利用1980年、1991年、2001年和2009年的高分辨率遥感影像以及GIS空间分析技术，基于现有的建设用地扩张指标建立了综合扩张度指数模型，并对新庄镇1980—2009年三个时间段建设用地扩张的总体特征和时空分异特征进行了定量分析。1980—2009年，随着农村城镇化和工业化进程的加快，新庄镇建设用地面积显著增加了19.24平方千米，尤其是在2001—2009年，扩张面积、扩张贡献率和扩张强度均达到最大值。建设用地扩张具有明显的空间分异特征。1980—1991年，新增建设用地主要集中在镇区。1991年以后，建设用地的重点逐渐向工业发达的村庄扩散。新增建设用地大部分由水田和旱地转化而来，占新增总面积的88.1%，而其他土地类型的贡献相对较小。
