摘　　要：本文提供了一种比较简单、易理解、可以快速提取遥感影像的变化信息的方法——基于主成分变换的方法,并就某一地区的两幅不同时相的影像进行变化检测,取得了理想的效果;对比了几种常用变化检测方法,验证了该方法简单、快速、高效的特点。The paper provides a simple, easy understood method which can quickly extract change information of remote sensing images -the method based on Prineipal Component A- nalysis. A change detection experimentation of two different ima- ges in a particular area was produced, the experimentation anal- ysis several eommonly used method of change detection, and the method based on Principal Component Analysis was proved to be simple, fast and effieientive.
