- Abstract:
-
After stopping mining, the mining lands had experienced 10 periods and 2 special ecological restoration projects during ten years in Mufushan Mountain of Nanjing. Based on sampling and analyzing remote sensing data in Mufushan Mountain, the index values between the early stage of restoration and the final period of restoration were calculated following the principle of ecology. Then, the Kriging method and spatial overlay function in ArcGIS were used to examine the spatial distribution of ecological restoration values in Mufushan Mountain. The results showed that the ecological restoration projects had created ecosystem values worth of 44.65 million yuan, in which the values created by the atmosphere, soil layer, vegetation layer and litter layer were 40.037 1 million yuan, 2.876 2 million yuan, 1.716 6 million yuan and 21 800 yuan, respectively. After the ecological restoration, the ecological environment of Mufushan Mountain was significantly improved. The recovery effects of ecological restoration projects existed difference. Meanwhile, the stable ecological restoration effects in Mufushan Mountain will be revealed after a period. Therefore, it is necessary to monitor the ecological succession in the ecological restoration area of the abandoned mining area and strictly protect the results of ecological restoration.
