摘要
本文根据实地调查和收集的近４０ 年资料， 分析了新亚欧大陆桥新疆段地质灾害类型及成灾方式， 阐明了该段以洪水、风沙灾害为主要类型的灾害特点， 通过对不同灾害类型的时空强分布统计分析，揭示了灾害过程 （春季， ３～４ 月以盐碱土不良路基、风沙灾害为主； 夏季， ６～７ 月份以洪水为主） 的时空活动特点和区域分异规律。
Based on field investigation and the statistical data of recent forty years, firstly, the types and disaster processes (courses) of geological hazard in New Eurasian Continental Bridge (Xinjiang) are analyzed The main disaster types have characterized by flood and wind-sandy hazards in Continental Bridge of Xinjiang Secondly, the law of temporal and spatial distribution of geological hazards was revealed The bad roadbed of saline-alkali soil and wind-sandy hazards occurred mainly during Mach to April and flood disasters occurred during June to July
