摘要
通过对雅鲁藏布江中游河谷典型山水林田湖草沙生态修复工程实施效果调查,针对露天采矿、灌草地退化、土壤沙化等突出生态环境问题,基于自然的解决方案,系统梳理并形成了地形地貌重塑、土壤基质重构、防沙治沙、植被恢复四大工程技术措施,对西藏山水林田湖草沙生态修复相关工程的实施具有一定借鉴和指导意义。
Through investigation of the implementation effort of the ecological restoration projects of typical mountains,rivers,forests,fields,lakes,grasslands and sandes in the middle reaches of the Yarlung Zangbo River valley,open-pit mining,shrub and grassland degradation and soil desertification have been recognized as prominent ecological and environmental problems.Based on the nature-based solutions,four major engineering and technical measures,namely terrain and landform remodeling,soil matrix reconstruction,sand prevention and control,and vegetation restoration have been systematically sorted out and formed,which have certain reference and guiding significance for the implementation of ecological restoration projects related to mountains,rivers forests,fields,lakes,grasslands and sands in Xizang.
