[Methods] Based on Google Earth images in 2003, 2010, 2015 and 2019, the land use remote sensing classification was carried out in Changshangou open-pin mine concentration area in Tangshan City, Hebei Province. The land use transfer matrix was calculated by using ArcGIS software, and the spatio-temporal characteristics and causes of land use change in the open-pin mine concentration area were analyzed. [Results] ① From 2003 to 2015, the area of greenland in the study area decreased by 169.61 hm2, accounting for 6.30% of the total area, and the area of bare land and industrial sites increased by 184.73 hm2 and 60.46 hm2, accounting for 6.86% and 2.25% of the total area, respectively; some arable land was occupied; spatially, greenland was mainly converted to bare land and industrial sites. ② From 2015 to 2019, the area of greenland in the study area decreased by 61.05 hm2, accounting for 2.27% of the total area, and the area of industrial sites increased by 43.90 hm2, accounting for 1.63% of the total area, with little changes in the area of other land use types; spatially greenland was transformed into bare land and industrial sites, with little change of the total area. [Conclusion] In the early stage of mining, a large amount of green land was occupied in the open pit mine, the vegetation destruction and land resource occupation was serious, and the ecological environment was seriously affected. At the late stage of mining, the ecological restoration and treatment of the mine were strengthened, and the effect of “management while mining” mode was initially achieved. %R 10.13961/j.cnki.stbctb.2021.04.017 %U http://stbctb.alljournal.com.cn/stbctb/home %1 JIS Version 3.0.0
