近20年来苏南地区城乡建设用地时空演变分析
spatial-temporal evolution analysis on urban and rural construction in Southern Jiangsu in nearly 20 years
通过对TM影像进行校正，利用NBI和NDVI提取苏南地区1991-2007年近二十年的城乡建设用地，综合景观指数，从城乡建设用地的规模、扩张速度、轴向扩张以及扩张模式等方面探讨1991-2007年间不同阶段的城乡建设用地扩张规律。结果表明：近二十年来，苏南地区城乡建设用地增长迅速，扩张强度突变的区域主要集中在城区，逐渐形成以沪宁高速公路为扩展轴的轴向发展模式，而且苏南三市城乡建设用地增长方式明显不同。通过对苏南地区城乡建设用地的时空演变分析，为城市发展分析和研究奠定了一定的基础。
hrough the calibration of TM images, NBI and NDVI were used to extract the 20 years urban and rural construction from 1991 to 2007. Combining the landscape index, the paper explored the expansion laws of the urban and rural construction from 1991 to 2007 in the scale of the construction, expand speed, axial expansion and expand mode. The result shows following, nearly twenty years, the construction growth rapidly in the Southern Jiangsu, and the expansion area focus on the urban areas, and formed the axial expansion mode that the Huning highway is expansion axis gradually. In addition, the expansion ways of the three cities are different obviously. Through the spatial-temporal evolution analysis on urban and rural construction, it can provide reference for analysis and research of urban development.
