| 摘 要： | 应用遥感技术分析了漯河市20年来的城市变迁情况。选用了TM、ETM、SPOT5三种遥感数据，在图像配准、直方图匹配等图像预处理的基础上，提出了一种用于城市变迁分析的新方法：差值主组分法。对1987年、2000年2009年三个时相的遥感数据应用该方法，得到了城区扩张的详细数据。最后分析了漯河市城市扩张的主要原因。

| Abstract: | The paper analyzed the urban changes of LuoHe in the past 20 years using remote sensing technology.Three kinds of remote sensing data TM ETM and SPOT5 were chosen.Difference Principal Component Transformation,a new method of analyzing urban changes was proposed on the basis of image registration and histogram matching.Detailed data of city expansion was obtained by contrast of three-phase remote sensing data:1987 2000 and 2009.Finally,the main causes of LuoHe expansion were analyzed. |
