| Abstract: | Extracting the ecological disturbances by using satellite imageries with high spatio-temporal resolutions is an important requirement in conservation planning and natural resources management. By systematically reviewing the relevant studies, this paper presented three methods for extracting the ecological disturbances by using satellite data. We described in detail the extracting methods of ecological disturbances based on three types of satellite imageries, including GF-1, Landsat and MODIS (Moderate Resolution Imaging Spectroradiometer).We also discussed the applicability and limitations of these three methods. |
