摘 要:乌达至吉兰泰运盐铁路穿越乌兰布和沙漠西南缘,全长130km,沙害极为严重。主要危害特点:由于修建铁路及通车以来人为经济活动的加剧,破坏了原有植被,导致沙化,危害铁路;风沙流是危害乌吉铁路的主要形式;由于风的多向性,使风沙作不规则的往复式摆动,造成铁路积沙;风沙危害严重地段集中在35~40km,47~52km,69~83km和99~105km等区间。通过对该线沙害程度、特点及自然因子的分析,提出“以封为主”,“封、飞、造”、“固、阻、输(导)”相结合的综合治理措施。The Wuda Jielantai salt transportation railway cuts across the southwestern part of Ulan Buh Desert, where the ever covered vegetation has been destroyed by railway building activity and economic activities since openning. Wind sand flow is the main calamity to the railway. Sand accumulation along the railway is violent due to the irregular shift of wind sand. Based on the analysis on sand calamity degree, characters and natural factors, integrated measures predominated by closing sand land method combined with afforestation by air seeding and mechnical measure at severe sand calamity section are put forward.
