Dynamic changes in landscape pattern in a large-scale

Coal is the main resource in China, and opencast mining plays an important role. The impact of coal mining on landscape ecology is huge. Based on the interpreted six-phase land use status map, the study analyzed the land use evolution process in Pingshuo opencast mining area of China using the land use degree index and land use fractal characteristics.
