摘　　要：采用"支持向量机分类"方法对上海市1987年和2007年的TM影像进行了解译.结果显示:近20年来的区域土地利用覆被变化表现为耕地和未利用土地的面积在不断减少,城乡建设用地、林地、草地、水域面积在不断增加;在空间格局的变化上,城乡建设用地的扩张虽然以从中心城区向外摊开方式为主,但沿交通轴向和卫星城镇点上的外拓发展趋势也非常明显;林地的增加主要集中于环城绿化带、森林公园、城市公园、居住区绿化等区域.根据区域社会-经济-生态复合系统变化与区域土地利用覆被结构变化间的相关性,利用"主成分分析法"和Excel统计功能,建立了两者间的线性相关模型.论文的研究结论可为政府部门科学合理地使用和管理上海有限的土地资源提供参考.The TM images of Shanghai in 1987 and 2007 were interpreted with ＂Support Vector Machine＂ method and the interpreted results showed that the regional LUCC was great in the past 20 years. The areas of the cultivated land and unused land were declining,while the ones of urban and rural construction land, woodland, grassland and water were increasing. As for the changes of LUCC in the space, the spread of the urban and rural construction display such patterns as both from - center - to - outside and along - traffic axial - or - surrounding satellite towns; the increment of the woodland mainly focused in the green forest belts around the city, forest parks, urban parks, residential green spaces, and so on. According to the correlation between regional social - economic - ecological complex system and the changes of LUCC ,the paper has used ＂Principal Component Analysis＂ and the Excel statistical function to establish a linear correlation model between them.
