摘要
广西是我国典型的岩溶石漠化地区,矿产资源丰富,生态环境脆弱,矿山开采对环境破坏较大,亟需进行矿山复垦。提出了矿山农业生态复垦所面临的主要问题:岩溶石漠化问题、土壤肥力问题、重金属离子污染问题,以及次生地质灾害问题。并从政策倾斜、工程治理、重金属污染土壤植物修复以及新技术的应用等方面阐述了治理对策。
The Guangxi is a typical karst rocky desertification area in China,rich in mineral resources,the ecological environment is fragile,and the ecological environment has been damaged very seriously affected by the impact of mining,so the mining areas reclamation is promptly needed.In this paper,the major problems faced by agro-ecological reclamation of mining areas are put forward,that are karst rocky desertification,poor soil fertility,heavy metal pollution,as well as secondary geological disasters.From preferential policies,regulation projects,phytoremediation of soils contaminated by heavy metals and application of new technologies,etc.,some countermeasures for the environmental improvement in mining areas are expatiateed.
