基本农田保护区内采矿废弃地的生态重建

首先区别了矿区废弃地恢复、复垦和生态重建3个概念；随后探讨了采矿废弃地生态重建的目标和措施；在分析中国现行技术存在问题的基础上，探讨了现阶段生态重建技术的研发与示范；最后提出了为进一步保护矿区内现有的基本农田和重建因采矿破坏的基本农田，还应加强矿区开采沉陷监测与预警的系统研究，构建采矿废弃地生态重建的政策保障体系,及探讨以土地整理项目促进采矿废弃地生态重建的可推广模式。

Ecological reconstruction of derelict mined-land in conservation areas of prime farmland

A lot of prime farmlands are derelict due to mining activities in China. The derelict mined-land usually locates in conservation areas of prime farmland, which brings about a series of eco-environmental and socio-economic problems. In this paper, the concept and implication of restoration, reclamation and ecological reconstruction were reviewed. The key objectives of ecological reconstruction were to enhance natural productivity of derelict mined-land, to establish complex ecolo-economic system, and to mitigate man-land contradiction. Accordingly, some countermeasures to realize ecological reconstruction were put forward. Based on analyzing the existing problems of reclamation technologies in China, technology development and demonstration of derelict mined-land were studied. In order to further protect existing prime farmland and reconstruct derelict prime farmland in mined areas, it is pointed out that the researches on systematically monitoring, preventing and alarming ground sinkage due to mining activities, establishing ensuring system for policy of ecological reconstruction of derelict mined-land, and probing the feasible model of ecological reconstruction promoted by land consolidation and rehabilitation projects should be strengthened.
