摘　　要： 基于多时相TM数据,对上海西南快速城市化地区近10 a来的土地利用变化进行分析研究;揭示了该区域各类土地利用数量变化的幅度、土地利用变化的空间分布特征、以及城市扩展强度;计算城市化成熟区中建成区用地面积密度值。通过城市化成熟区和各实验区建成区用地面积密度值的比较,制定“城市化进程指数”,进行城市化空间过程的刻画。 Based on the multi - temporal remote sensing image data, the authors have analyzed the land use change of axial urbanization growth on the southwestern margin of Shanghai in the past 10a or so, investigated and obtained the variation quantity of all kinds of land use, the features of spatial distribution of land use change, and the intensity of urbanization growth. The density of developed areas in the mature urbanized district is also calculated. By comparing the density between the developed areas in the mature urbanized district and every test block, the authors have formulated ＂the process index of the urbanization＂, and carried out the portrayal of the urbanized spatial process.
