矿山土地复垦与生态重建技术研究现状与展望

Status Quo and Prospect of Research on Technology for Mine Land Reclamation and Ecological Reconstruction

总结了国内外土地复垦与生态重建的现状,介绍了复垦土壤的侵蚀控制技术及其产业化,水利播种与覆盖技术,人造"表土"技术,矿山固体废充物复垦中的高效生物技术,尾矿多层覆盖技术等土地复垦技术的新进展;提出了当前及今后4个重要研究领域:酸性矿山废弃物污染预防技术,边坡地下水土流失防治技术,土壤重构与培肥技术,复垦地貌恢复与景观设计。

The status quo of land reclamation and ecological reconstruction both in and outside China and the new progress in the technology for land reclamation are presented, including reclamation soil erosion control technique and its industrialization, water conservancy, seed sowing and covering technique, man-made ＂surface soil＂ technique, effective bio-technique in the reclamation of mine solid waste, multi-covering technique of tailings. The present and future four research fields are suggested ： technique of preventing the pollution of acidic mine waste, technique of preventing and controlling the water and soil loss under the slope, technique of soil reconstruction and fertility cultivation, and technique of topographic restoration and landscape design in land reclamation.
