Study on the Restoration of Ecological Environments in Mining Area Based on GIS Technology

Taking Erdaojiang and Dongchang District of Tonghua City, Jilin Province as examples, this paper studies the ecological environment restoration governance model their mining areas. In paper, vegetation cover (NDVI) data in past ten years were selected from study area. The Theil–Sen median Mann–Kendall (MK) methods used to analyze time series NDVI, change trend map area was obtained. Then, land use for 4 selected, transfer matrix method conversion between years. Finally, according characteristics distribution mines area, different natural geographical locations, it concluded that cultivated forest reconstruction adopted. Among them, includes artificial intervention.
