南水北调中线弃土弃渣场生态修复初探

Preliminary Study of Ecological Restoration of Waste Soil and Slag Yard of South-to-North Water Diversion Middle Route Project

南水北调中线应急供水工程作为先期实施工程已经建成并投入使用。应急供水工程河北段大量的弃土弃渣和弃土弃渣占地,不仅为水土流失输送了大量的物质源质,也使项目区生态退化。结合中线应急供水工程河北段弃土弃渣情况和生态修复情况,分析了弃土弃渣可能带来的生态问题,探讨了弃土弃渣场生态修复措施与技术,总结了生态修复经验与教训,为南水北调中线工程生态修复提供技术参考。

Being early implementation project,the emergency water supply project section of South-to-North Water Diversion Middle Route Project has been built up and put into operation.But lots of land occupation by Waste Soil and Slag of the project in Hebei province not only lead to soil and water erosion,but also cause ecological deterioration.Based on the conditions of waste soil and slag and ecological restoration situation in this area,this paper focused on analysis of the ecological problems that possibly caused by Waste Soil and Slag,studied ecological restoration measures and methods of Waste Soil and Slag and then finally summarized the experience and lessons for ecological restoration,which could provide technical references for ecological restoration of the South-to North Diversion Middle Route Project.
