高寒高海拔区弃渣堆生态修复技术研究综述

Review on Ecological Restoration Technology Research of Waste Dumps in High-Cold and High-Altitude Areas

川藏铁路高寒高海拔段拥有独特的生态环境和地理特征,大量隧道弃渣需要堆积,导致弃渣堆的生态修复成为川藏铁路工程建设的一大难题。基于此,本文通过大量文献整理,总结前人在高寒高海拔区的生态修复研究成果,以期为川藏铁路高寒高海拔区弃渣堆的生态修复提供思路。总体来说,要做好土壤基质保育、改良与重构,合理进行植被群落配置,综合运用生态修复技术,最终实现高寒高海拔区弃渣堆的生态修复。

The high-cold and high-altitude sections of the Sichuan-Tibet Railway have unique ecological environment and geographical characteristics,and a large amount of tunnel waste needs to be piled up,resulting in the ecological restoration of waste dumps becoming a major challenge in the construction of the Sichuan-Tibet Railway project.Based on this,this paper summarizes the ecological restoration research results of predecessors in high-cold and high-altitude areas through a large number of literature review,in order to provide ideas for the ecological restoration of waste dumps in high-cold and high-altitude areas of the Sichuan-Tibet Railway.Overall,it is necessary to do a good job in soil substrate conservation,improvement and reconstruction,reasonably configure vegetation communities,comprehensively apply ecological restoration technologies,and ultimately achieve ecological restoration of waste dumps in high-cold and high-altitude areas.
