- Abstract:
- In this thesis,multi-temporal landsat TM image is used for analysis of surface vegetation change between 1988 and 2000 in Fuzhou,through the methods of change detection and Pseudo color synthesis.However,the resultant different images of NDVI contained false change information that was not produced by the vegetation change.Therefore,a series of thresholds had to be determined to distinguish the false change information from the true one and mask out the false information from the different images.The results prove that using different multi-temporal landsat NDVI image to color synthesis can reflect the change of the surface vegetation directly.And as mask out the false information from the images,the precision of images is improved.Overall,the surface vegetation of Fuzhou has increased during the study years,at the same time,some area’s surface vegetation became degenerated owing to human activity.
