摘要: 针对当前土地利用/覆盖变化动态监测中常用的分类后比较法中存在的误差累积 ,夸大变化程度的缺陷 ,提出了把变化矢量分析和分类后比较法相结合进行混合动态监测的新方法。从北京市海淀区的实例研究来看 ,尽管该方法对单景图像分类精度提高不明显 ,却可以大大降低常规分类后比较法中误差累积的程度 ,改善了常规分类后比较方法中误差累积、出现不合理变化类型的缺陷 ,从而得到较为准确的土地利用/覆盖变化定量信息。

Abstract: In the current land use/cover change detection,post classification is often used for its little limitation to radiometric correction.However,as the error in the individual date classification map will also be present in the final change detection map and usually causing the fault of the change detection,a new change detection method combining Change Vector Analysis (CVA) and Post classification is thus given in this paper.From the result of the case study in Haidian District of Beijing,one can see that the error in post classification was reduced greatly and the relatively reliable land use/cover change information was also obtained,although the shortcoming of error accumulation can not be solved entirely.

Key words: change vector analysis, post classification, land use/cover change, Haidian District, Beijing
