【摘要】：新建临河至策克铁路天鹅湖至额济纳段位于我国著名的胡杨林国家自然保护区与巴丹吉林流动沙漠边缘。额济纳胡杨林自然保护区,占地48万亩,呈南北走向,胡杨林是在恶劣干旱荒漠地区顽强生存着的生命。为保护胡杨林—不死的活化石这一珍稀植物,临河至策克铁路天鹅湖至额济纳段进行了大面积风沙区地质选线,查明了流动沙丘区风沙流动特征及其发育、发展规律,选取沿沙丘活动最弱地段通过方案,最大程度降低风沙对铁路危害,节省了大量工程投资。
[Abstract]:The section between Swan Lake and Ejina on the Linhe to Zeke railway is located at the edge of the famous Populus euphratica National Nature Reserve in China and the floating desert in Badain Jilin. The Ejina Poplar Forest Nature Reserve covers an area of 480,000 mu and has a north-south trend. Populus euphratica forest is an indomitable life in arid and desert areas. In order to protect Populus euphratica, a rare plant, the section between Swan Lake and Ejina of the Linhe to Zeke railway has carried out geological route selection in a large area of windy and sandy areas. The characteristics of wind-sand flow and its development and development in mobile dune area are found out. The project is adopted in the weakest section along the sand dune, which reduces the harm of wind-sand to railway and saves a lot of project investment.
