This study is based on 2018 Xuanxia mining area high resolution satellite images and related data in Zhangjiakou,uses re-mote sensing technology,analyzes land use type,vegetation coverage,soil erosion intensity in the research area,obtains the habitat quality,water network density,land stress indexes,and conducts analysis and evaluation of the ecological environment condition in the research area. The results show that the topographic classification of the study area was mainly mountainous and hilly,with the highest proportion of medium vegetation coverage,mainly micro soil erosion intensity,and serious soil erosion in some areas. Com-bined with the comprehensive analysis of other ecological environment status evaluation indicators,the ecological environment status of the study area in 2018 is relatively poor.
