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。
In this paper, the ecosystem service function of land reclamation in abandoned mining area is taken as the research object. Based on the theory of land suitability evaluation, a multi-scenario simulation method of land reclamation in abandoned mining area is established. Land reclamation in abandoned mining area is divided into three types: Reclamation, land reclamation and comprehensive forest land reclamation, forest land reclamation and other four kinds of scenarios, and the land reclamation in abandoned mining areas in Anhui Province as an example to measure the value of these four different types of reclamation services ecosystem services . The results show that the net benefits of ecosystem services in these four scenarios are 521 million yuan, 30.916 billion yuan, 31.159 billion yuan and 34.369 billion yuan, respectively, which shows that the net benefits of ecosystem services corresponding to different scenarios of land reclamation in abandoned mining areas The ecological benefits of land after reclamation are better than the ecological benefits of reclamation, and the ecological benefits of forest land as the main reclamation method are the best; the net benefits of land ecosystem services after reclamation are Is positive, indicating that the ecological value of reclamation is higher than the input cost.
