“风雪流”是一种常见的自然灾害,在地球上分布广,不仅诱发并加重雪崩、泥石流等自然灾害,而且直接给交通、农牧业和人民群众的生产生活造成严重损失。我国新疆一些国道在穿越天山附近时,风雪常常埋没路面,造成每年冬季4～6个月不能通车。 “Wind and Snow Flow” is a common natural disaster that is widely distributed on the earth. It not only induces and aggravates natural disasters such as avalanches and mudslides, but also directly causes serious losses to the production and life of transportation, agriculture and animal husbandry, and the people. When some national highways in Xinjiang pass through the Tianshan Mountains, winds and snow often bury the road surface, causing the traffic to be shut off for 4 to 6 months each winter.
