Monitoring and Spatiotemporal Variation Analysis of Vegetation Coverage in Iron Mining Area Around Anshan
The vegetation of mining area plays an important role in maintaining soil stability and pre-venting the erosion of mineral resources.Based on Landsat5 TM/Landsat8 OLI images,the vegetation change of Anshan iron mining area in the past 40 years is monitored and analyzed.The results show that us-ing pixel dichotomy to calculate the vegetation coverage of the mining area,the vegetation coverage of the north and west of the study area is low,and the vegetation coverage of the southeast area is mostly extended to Qianshan Mountains,and the vegetation coverage of the study area is high.In terms of space,the north and west are mostly low vegetation cover areas,there are two high vegetation cover areas in the middle,the southwest is mostly low and medium vegetation cover areas,and the southeast is a large area of high cover-age areas.In terms of time,the vegetation coverage of mining area show,a decreasing trend.The expansion of mining area and the construction of tailing pond occupied vegetation area have caused irreversible damage to vegetation in mining area.
