%X Change Vector Analysis (CVA) is a valuable approach for land use/cover change detection, in which how to determine change magnitude threshold and change direction reasonably is already becoming an obstacle for its widely use. Therefore, a new method named Double Windows Flexible Pace Searching is proposed in this paper aimed at determning change magnitude threshold reasonably and efficiently. As a result from the case study in Haidian District, Beijing, the accuracy of change detection is obtained about 87%, which indicates that the Double Windows Flexible Pace Searching method has potential utility in Change Vector Analysis for land use/cover change detection.
