High-Resolution Satellite Application in Land Cover Change Detection

Abstract

Based on the RS and GIS technology , interpret two high-resolution images as well as statistics and analysis the area of land cover change in order to realize the spatial distribution and change trend of land cover change for a decade.Research results show that the change of woodland area is the largest, reduce 29.48 km2; The minimum area of bare earth is only 0.20 km2; Other classes have different degree of change, in the west of the study area has taken place obviously change, mainly in the northwest of shrubs, the east has no obviously change;And the northwest areas with significantly changed about river, marshes and spatial distribution of grassland is basically in a stable state, the overall change in the study area change small scale. Studies have show that nearly a decade the Shuanghe nature reserve ecological environment to be protected well.
