摘　　要：利用1961—2007年长达47a高速、高等级公路沿线气象站的资料,重点研究北疆高速、高等级公路沿线冬季影响车辆安全行驶的气象要素的气候特征,分析该路段降雪、积雪、结冰、冻雨等气象要素的时间和空间分布,并依据气候分布特点从气候的角度将北疆高速、高等级公路沿线路段按降雪、积雪、结冰、冻雨等对行车安全影响程度划分为极易打滑路段、较易打滑路段、易打滑路段和不易打滑路段,为公路管理部门提供科学的、合理的防御和减少冬季交通事故的理论依据。The climate charateristics of Weather Fators of influencing travel were studied on the basis of observation data from weather stations along the freeway and high-grade road of north Xinjiang during 1961-2007.The temporal and space distribution of Weather Fators,such as snowfall, snow accumulation,ice-up,freezing rain,and etc, was analyzed,and four sections of a highway, terribly skid one, rather skid one, skid one and no-skid one, were divided according to the distribution and influence degree of Weather Fators. It could provide theory foundation for road Administrator in decision making for scientific and reasonable prevention of weather disaster.
