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
