高寒灌丛草甸区的弃渣体场地生态修复技术研究

STUDY ON ECOLOGICAL RESTORATION TECHNOLOGY OF RESIDUESDISPOSALAREA IN ALPINE SHRUB MEADOW AREA

川藏铁路的建设将带来大量弃渣堆积,弃渣场裸露边坡会造成一系列生态地质问题,本文以高寒灌丛草甸区的弃渣体场地为例进行了生态修复技术研究工作。首先分析了工程区生态恢复的关键制约因子,在明确高寒灌丛草甸区域特点的基础上,采用原有植被移植利用技术和建植修复技术方案。在弃渣场生态修复上做到人工修复与自然恢复相结合,充分利用自然的恢复潜力,促进渣场自然演替和群落稳定,使之与周围环境相互协调。

The construction of Sichuan-Tibet railway will bring a lot of residues accumulation,and the exposed slope of residues disposal area will cause a series of eco-geological problems.In this paper,we studiedthe ecological restoration technologyof residues disposal area in alpine shrub meadow area.Firstly,the key restricting factors of ecological restoration in the project area were analyzed.Based on the regional characteristics of alpine shrub meadow,the original vegetation transplantation and utilization technology as well as vegetation restoration technology were adopted.In the ecological restoration of the residues disposal area,the combination of artificial restoration and natural recovery should be achieved,and the natural restoration potential should be fully utilized to promote the natural succession and community stability of theresidues disposal area,whichleads to coordinate with the surrounding environment.
