摘　　要：以郑州市为研究对象,选取2000、2006、2008和2012年4期遥感影像,运用RS数字图像处理技术和GIS空间分析技术,通过空间方位比重等多种指标综合考虑多种因素详细分析2000-2012年中原经济群中心城市——郑州市城市空间扩展动态变化轨迹。结果表明：2000年以来,郑州市区的城市扩展明显,但速度逐渐放缓,扩展方向以向东为主,呈东西南方向发展;城市扩展经历了从以外部延伸和边缘扩展为主到以内部填充和边缘扩展的转变,表明了城市建设正朝着土地利用集约化方向发展;人口、经济、交通以及政策因素是促进郑州市城市快速扩展的主要原因,其中政策因素起到了主导性作用。Taking Zhengzhou as the research object with the help of the four temporal Landsat TM and ETM ＋ remote sensing data of 2000,2006,2008,2012,using image processing technology of remote sensing（ RS） and spatial analysis technology of GIS and considering all the influencing factors by synthesis,the article mainly uses many indexes including the proportion of spatial orientation to study the dynamic changes of urban expansion in Zhengzhou,one of the central plains economic group,during four years of 2000,2006,2008,2012. The results mainly show that since the beginning of the 21 st century,the urban expansion of Zhengzhou had increased significantly,but the speed was slowing,and the urban developed towards to the east,the west and the south,but the east is the major direction; urban expansion of Zhengzhou in 12 years varied from external extension and edge extension to internal filling and edge extension,indicating that land use got intensive gradually;Population,economy,traffic and policy are the main factors,but the policy plays a leading role.
