- Abstract:
-
We studied the characteristics and influencing factors of spatial and temporal change in vegetation coverage in Shendong mining area by linear trend regression analysis and Hurst index, and predicted the future trends of vegetation change, based on Landsat-NDVI data from 2000 to 2017, providing a reference for the environmental management of coal mining areas in the arid regions of northwest China. The results show that vegetation NDVI in Shendong mining area demonstrated an uptrend from 2000 to 2017, with an average growth rate of 0.069/decade. Analysis of the trend of vegetation change showed that 94.78% of the area had improved and 5.22% had degraded. The farmland abandonment caused by the village relocation in the mining area, and the subsidence area management project implemented in recent years promoted a positive development of vegetation, while the open-pit coal mining, untreated dumping sites, and the urbanization caused vegetation degradation. The overall vegetation will improve continuously in the future from the vegetation change trend analysis. The improved area accounted for 86.66% of the total mining area and the continuous degradation area accounted only for 4.48%. Area turned from degradation to improvement accounted for 0.74% but 8.12% converted conversely. In summary, the vegetation had been significantly improved from 2000 to 2017 in Shendong mining area, and there will still be a trend of continuous improvement in the future.
