    摘要:绿色基础设施(Green Infrastructure,GI)概念的提出是21世纪欧美国家应对城市蔓延、促进城乡生态系统健康发展的重要手段之一。矿业废弃地作为一种生态系统严重受损的土地类型,经过生态恢复和重建,是连接中断的生态过程、恢复与重建城乡生态系统的重要土地资源,是GI网络构建的重要组成部分。从生物多样性、生态系统服务功能等角度阐述了矿业废弃地对于改善GI结构、提升GI功能的潜力和作用。通过案例研究证明GI规划是指导矿业废弃地生态恢复的有效工具。

    Abstract:Green Infrastructure is one of the most important tools for controlling urban sprawl and promoting urban and rural ecosystem healthy development in Western countries in 21th century. As one kind of serious destroyed ecological space, abandoned mine land also could be the key component of GI after restoration, which could connect the broken ecological course and enhance the ecosystem functions. The role and potential of abandoned mine land in compensating and improving GI system are clarified, by the view of bio-diversity and ecosystem service function under different restoration objectives. The GI cases of developed countries are analyzed, which can prove that GI is the effective regional approach of abandoned mine land reconstruction.
