摘要
广西是我国的金属之乡,矿产资源蕴藏量大,但末期矿山多,地质环境薄弱,金属矿山引起的地质环境问题尤为突出,亟需复垦。总结了广西金属矿山复垦及生态恢复重建模式,包括分区采样、实验分析、污染评价、生态复垦及系统重建等。介绍了我国在矿山污染评价、矿山复垦规划与前期处理、土壤污染修复、超富集植物筛选、生态恢复评价等方面所进行的实践。探讨了今后广西矿山复垦与生态重建工作的发展方向。
Guangxi is a ＂ the country of nonferrous metals＂ in China,in which the reserves of mineral resources is very large,but there are many late mines,the geological environment is weak,so geological environmental problems in the metal mines is particularly prominent,mine reclamation is urgent need. This paper summarizes the reclamation and ecological restoration and re-construction models of metal mines in Guangxi,including area sampling,laboratory analysis,pollution assessment,ecological reclamation and system renewal and other means. The practices in the pollution assessment,reclamation planning and pre-processing,soil pollution repair,hyperaccumulator screening,ecological restoration evaluation of mines in China are introduced also. Finally,the future development direction of reclamation and ecological reconstruction for mines in Guangxi is discussed.
