| 摘 要： | 本文以废弃矿区土地复垦的生态系统服务功能为研究对象,基于土地适宜性评价理论建立了废弃矿区土地复垦的多情景模拟方法,将废弃矿区土地复垦划分为不进行复垦、以耕地复垦为主、以耕地及林地综合方式复垦、以林地复垦为主等4种情景,并以安徽省废弃矿区土地复垦为例证测算这4种不同复垦方式的生态系统服务功能价值。研究结果表明,这4种情景下的生态系统服务功能净效益值分别为5.21亿元、309.16亿元、311.59亿元、343.69亿元,说明废弃矿区土地复垦不同情景对应的生态系统服务功能净效益存在较大差异,复垦后土地的生态效益均优于不复垦的生态效益,且以林地为主要复垦方式获得的生态效益最佳;复垦后土地生态系统服务功能净效益值均为正,说明复垦产生的生态价值高于其投入成本。

| Abstract: | Mining ecosystems are one of the great ecological systems on earth. With deepening research on mining ecosystems,researchers have paid more and more attention to establelishing a method for abandoned mine land reclamation. Based on the theory of land suitableility evaluation we adopted the ecosystem service function of land reclamation of mining areas and establelished a multi-scenario simulation method of abandoned mine land reclamation. We created four scenarios: (1)no-reclamation,(2)arable land reclamation as the main method,(3)forest land reclamation as the main method,and(4)both of the methods. Taking abandoned mine land reclamation of Anhui,we measured the ecosystem services value of the four scenarios. The results show that the net value of ecosystem services of the four scenarios was 0.52 billion CNY, 30.92 billion CNY, 31.16 billion CNY, and 34.37 billion CNY(scenario 1 to 4 respectively). This indicates that the net value of ecosystem services is different between the four scenarios,compared to the ecosystem services of no-reclamation,they all resulted in higher ecological values after reclamation,of which forest(scenario 3)benefited the most. The net benefit of the land ecosystem service function value was positive after reclamation,reflecting that the ecological value was higher than the cost of land reclamation. The mining ecological environment in the study area is degenerated and may become worse unless the efficient management of mining and effective reclamation in mining areas are carried out instantly. |
