摘　　要：青藏公路于 2 0世纪 5 0年代初建成通车以来 ,特别是 70～ 80年代黑色路面铺筑后 ,冻土环境不断恶化。基于近 5 0年来青藏公路沿线环境演化规律 ,分析冻土环境与生态环境及工程稳定性三者之间的相互依赖关系 ,提出保护冻土环境和生态环境的对策措施。The permafrost conditions of Qinghai-Tibet Highway is going worse and worse after opening to traffic in the 1950s, especially after the construction of blacktop of the pavement in the 1970s to 1980s. On the basis of the environmental evolution rule along Qinghai-Tibet Highway, the analysis of the inner-relations of frozen soil conditions, ecological environment and foundation stabilization is carried out, the counter-measures for protection of frozen soil and ecological environment presented which is valuable for the design of environment protection and highway in permafrost region.
