Immediately after 2004, the mining core area was transferred for the Fujiawu mining area in the southeast.Remote Sens. 2021, 13,Remote Sens. 2021, 13, x FOR PEER Evaluation 10 of9 ofFigureFigure six. of damage year (a) (a) and reclamation year(b); statisticaldiagram ofof the harm region,and andreclamation 6.

There are actually 12 total restoration area is 544.95 ha withareaaverage annual to 2020 of 16.03 6b,d), and the years in which the vegetation restoration an isannual recovery of 16.03 ha. There are 12 years in which the vegetation restoration region is greater than the average, and also the maximum worth is 51.66 ha in 2020. The total region of organic or artificial restoration is steadily rising, mostly from 1994 to 1997, 2001, and 2017 to 2020. In the distribution of ecological restoration in Dexing mining area, from 1994 to 1997 and 2001, it was mainly concentrated in No. 1 tailing reservoir, No.Remote Sens. 2021, 13,10 oftailing reservoir, and scattered in Xiyuan dump web page. From 2017 to 2020, the intensity of vegetation restoration enhanced obviously, and also the north of No. 4 tailing reservoir, Zhujia dump web-site, Fujiawu mining area and also the location scattered in Xiyuan dump site were concentratedly restored. We additional investigated the year of damage and reclamation for each and every pixel and counted the amount of pixels inside a three-year cycle. The outcomes are shown in Table 1, in which the horizontal row represents the year of reclamation as well as the vertical column represents the year of destruction. The results show that the number of pixels of land broken in the 1986988 period was 5075, of which 55.8 of pixels had been reclaimed. The earlier the land was broken, the greater the probability of restoration. Right after 2004, the vegetation reclamation price of damaged land was less than ten .Table 1.

Months and Instances of Surface Disturbance The surface disturbance (damage and restoration) in the Dexing mining region will occur all through the year (Figure 7). The mining in every month is greater than 1500 detection pixels, plus the highest amount seems in July that is extra than 3500 pixels, when the followed highest amount months are March and September. The mining disturbance is significantly less in January, February, October, and December, mainly due to.
