内蒙古暴雪灾害的成因与减灾对策

The Cause of Heavy Snow Disaster Formation and Countermeasure of Decreasing Disaster in the Inner Mongolia

分析了暴雪灾害的成因。冬季的低温加暴雪形成深厚的积雪，这种积雪不但能掩埋牧草，影响家畜采食，而且增加了家畜的体能消耗，使大批家畜冻饿而死，从而形成了白灾。气候变冷、环境恶化及载畜量过大，都会加重白灾，而暴雪、大风加大幅度降温能在短时间内使家畜迅速丧失保持正常体温的能力，造成家畜大批死亡，这就是暴风雪灾害。提出了加强灾害预警，以防为主的减灾对策。

The causes of heavy snow disaster formation were analyzed. Low temperature and heavy snow falling in winter have the ability to form deep snow cover. The snow cover not only could bury pasture and affect domestic animals to eat, but also increase domestic animals' bodies energy to be exhausted, and lead a lot of domestic animals to die of severe cold and hunger. Thereby it came into being heavy snow disaster. The colder climate, bad environment and heavy carrying quantity of domestic animals would make the snow disaster more severe. Moreover, heavy snow, strong wind and a wide range of temperature fallen should make the ability to keep their bodies regular temperature of domestic animals lose rapidly in short time, and make a lot of domestic animals dead. This is so-called snowstorm disaster. The decreasing disaster countormeasures, to strengthen predicting and warning disaster and put the prevention first, were put forward.
