冶金矿山生态修复技术的进展

Research Progress of Ecological Restoration Technology for Wastelands in Metallurgical Mine

冶金矿山废弃地是对矿产资源进行开发利用时在地球表面留下的"疤痕"。近年来,冶金矿山废弃地的生态修复工作受到越来越多的重视。阐述了冶金矿山废弃地生态修复的必要性及国内外现状;详细介绍了国内外铁矿废弃地常用的土壤改良技术、植被恢复技术、边坡治理技术,以及再利用模式;同时指出了加紧开展废弃矿山的生态修复工作,应当成为今后我国环境治理的重点。

The wastelands in metallurgical mines are the remained scars on the earth surface after mineral resources were exploited. In recently years, the ecological restoration of wastelands in metallurgical mines has drawn more and more attention. The necessity of ecological restoration for the wastelands in metallurgical mines and the present situation of the restoration technologies at home and abroad were explained. Then some frequently-adopted technologies at home and abroad for ecological restoration of wastelands in an iron mine such as the soil improvement technology,vegetation restoration technology, treatment technology for side slopes and reutilization technology were introduced in detail. Meanwhile it was stated briefly that the ecological restoration in mining areas should be launched with greater intensity and the restoration was supposed to be the high focus among the comprehensive ecological improvements in China in the future.
