【摘要】：新建臨河至策克鐵路天鵝湖至額濟(jì)納段位于我國(guó)著名的胡楊林國(guó)家自然保護(hù)區(qū)與巴丹吉林流動(dòng)沙漠邊緣。額濟(jì)納胡楊林自然保護(hù)區(qū),占地48萬(wàn)畝,呈南北走向,胡楊林是在惡劣干旱荒漠地區(qū)頑強(qiáng)生存著的生命。為保護(hù)胡楊林—不死的活化石這一珍稀植物,臨河至策克鐵路天鵝湖至額濟(jì)納段進(jìn)行了大面積風(fēng)沙區(qū)地質(zhì)選線(xiàn),查明了流動(dòng)沙丘區(qū)風(fēng)沙流動(dòng)特征及其發(fā)育、發(fā)展規(guī)律,選取沿沙丘活動(dòng)最弱地段通過(guò)方案,最大程度降低風(fēng)沙對(duì)鐵路危害,節(jié)省了大量工程投資。
[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.
