摘　　要：兰张三四线铁路走行于河西走廊,区内遗留有数目众多的古遗址、古墓葬及古长城,且沿线居民区密布,饮用水水源保护区众多,走廊两侧大面积分布有自然保护区、沙化土地封禁保护区等生态环境敏感区。针对铁路走廊区域的人文历史、自然环境特点,明确工程面临的主要环境问题,制定环保选线及设计原则;针对工程涉及的自然保护区、饮用水水源保护区、文物保护单位等环境敏感区,通过优化设计方案、细化工程布置、创新环保措施等手段,确保工程环境保护措施可行,环境影响可控,实现工程建设与生态环境保护的协调统一,为其他铁路工程涉及同类环境问题提供基础理论依据和实践参考。The third and fourth line of Lanzhou-Zhangye railway run along the Hexi Corridor,where a large number of ancient sites,ancient tombs and ancient Great Wall are left behind,with dense residential areas and numerous drinking water source protection areas along the line.There are ecological environment sensitive areas such as nature reserves and desertified land closed protection areas distributed in large areas on both sides of the corridor.According to the characteristics of human history and natural environment in railway corridor area,the main environmental problems faced by the project are clarified,and the principles of environmental protection route selection and design are formulated.In view of the environmental sensitive areas such as nature reserves,drinking water source protection areas and cultural relics protection units involved in the project,by optimizing the design scheme,refining the project layout and innovating environmental protection measures,the project environmental protection measures are feasible and the environmental impact is controllable,so as to realize the coordination and unity of project construction and ecological environmental protection,and provide basic theoretical basis and practical reference for other railway projects involving similar environmental problems.
