Feitsui Reservoir Administration authorize NTU using satellite imagery supported by aerial photo, analyze the change variation of the distribution and surface area in tea garden and the cemetery. To provide the reference of the reservoir watershed land use variations, and thus maintain the reservoir water security. This project will use 2002 SPOT satellite images and 2012 FORMOSAT-2 satellite images. By normalized difference vegetation index (NDVI), image spectral features and digital terrain model to analyze two annual image features, differentiate land-cover like tea garden, cemetery, other agricultural and buildings, and match the growth and distribution with each kind of land cover。Finally, using the year 2008 aerial photos and on-site verification to correctness verification for the tea garden and cemetery two types of land-use coverage。 The results of this project can help Feitsui Reservoir Administration to grasp the land development situation and the spatial and temporal variation of the watersheds area, sustainable watersheds management, to ensure and maintain the quality of household water in the greater Taipei area.翡翠水庫集水區土地使用變異標準化差異植生指數影像光譜特徵數值地形模型Feitsui Reservoir WatershedsLand Use VariationNormalized Difference Vegetation IndexImage Spectral FeaturesDigital Terrain Model
