| 摘 要： | “世界屋脊”的青藏高原是中低纬地带面积最大的高原多年冻土区。该区的生态环境和地质环境十分脆弱 ,而线型工程本身的特点加之施工管理不当 ,会造成沿线冻土环境和生态环境的恶化。本文探讨了该区线型工程及其沿线生态环境的相互作用机制 ,提出了为维护线型工程的稳定和保护沿线生态环境在施工和管理上应采取的措施

| Abstract: | Tibetan Plateau,known as "the ridge of the world", is the largest permafrost area in the low-middle latitudinal zone of the earth. The ecological and geological environment is very fragile in this area. The environment of frozen soil and ecology is always deteriorated by the linear engineering and the improper construction or management. This paper discusses the inter acting mechanism between the linear engineering and ecological environment in this area. The measures of construction and management are given for the stabilization of linear engineering and the protection of ecological environment. |
