基于生态价值的幕府山采矿废弃地修复效果评估

南京幕府山停止采矿后，在10 a间经历了10期和两个专项的生态修复工程。为了解生态修复效果，在对幕府山野外调查采样和遥感数据分析的基础上，遵循生态学原理，对比了幕府山生态修复初期和修复后的生态服务价值量，并进行了可视化处理。结果表明:生态修复工程共创造生态服务价值4 465.17万元，其中，大气层、土壤层、植被层和枯落物层创造出的价值量分别为4 003.71万元、287.62万元、171.66万元和2.18万元。经生态修复，幕府山的生态环境得到显著改善，但不同修复工程的修复效果存在差异；稳定的生态修复效果有待时间的积累，需长期监测采矿废弃地生态修复工程区的生态演替，严格保护生态修复的成果。

Assessment of Restoration Effects of Abandoned Mining Lands in Mufushan Mountain Based on Ecosystem Value

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.
