The source region of the Yellow River is facing with problems of local ecosystem degradation and reduction of water conservation function, and the ecological environment in the source region of the Yellow River is fragile. Mining development is one of the key factors affecting the ecological environment in the source region of the Yellow River. Based on the high-resolution remote sensing satellite data of 2015 and 2018, this paper carried out the monitoring of the current situation and dynamic changes of the mine environment in the source region. The results show that the main mine environmental problems, caused by mining development, in the source region are land excavation and land occupation, and the growth rate is pretty fast. At present, the recovery rate of mines is low, only 25.24%. According to the present situation of mining environment, regional physical geography and other factors, the mine damaged land in the source region of the Yellow River is divided into three types: the natural restoration areas, the general restoration areas and the key restoration areas. The ecological restoration of mines in the source region should adhere to the strategy of taking measures according to local conditions, and offer specific ecological restoration proposals for each type of areas. The ecological restoration of mines in the source region should focus on water conservation, strengthen the restoration of stocking mine damaged land, study the permitting mechanism of mining activities, and reinforce the function of regional ecological protection.
