摘要：Mu Us Sandy Land (MUSL) in northern China as a typical eco-fragile region contains approximatelyone-third of the Chinese coal reserves. The region has a long history of coal mining with prolongedhuman-induced activities that might accompany aeolian desertification development. Since China startedimplementing the western development policy in 2000, the mining activity has expanded rapidly inthe MUSL region and impacted strongly the sustainable socioeconomic development. Up till now, onlyscattered information on these activities is available from specific studies. In this paper, based on theLandsat TM, ETM, and OLI images from 2000, 2005, 2010, and 2013, we monitor systematically theexpansion of coal mining activity using the mining regions as an indicator and the changes of the landcover type due to the expansion of mining activity in the MUSL region. Based on these data, we developeda database of mining region by introducing a mining region classification system and use it to discussthe spatial and temporal evolution trends of mining activity. The obtained results provide evidences formanagers to evaluate the execution of government planning and the effect of rapidly expanded miningactivity on the local ecological environment. .
