阿勒泰地区牧业转场中风害的分析及防御对策

分析了造成春季牧业转场中大风天气的环流特征及阿勒泰地区的牧业特点.指出:造成春季牧业转场中大风天气的主要类型有四种,其中脊(阻高)衰退类、脊发展类、咸海-乌拉尔山低槽类是造成偏西大风的环流形式;西伯利亚、新疆高压脊(阻塞)型是造成偏东大风的环流形式.风害不仅加剧了羊群的热损耗率,易形成冻害,而且风速过大时,还会引起跑群;牧业转场时应采取积极的防御措施,将损失减少到最小.

Analysis and Defensive Measure on Gale Disaster of Animal Husbandry Transferring in Altay Area

The circulation character which has formed the gale weather during animal husbandry transferring in spring and the feature of animal husbandry in Altay area has been analyzed. The experiment result indicated that there were four main kinds of reasons which formed the gale weather during animal husbandry transferring. They are ridge (obstructed plenum) decaying、ridge developing、the Salt sea-the Ural Mountains formed the circulation character which blow the gale towards west; the Siberia and Xinjiang height ridge obstruction formed the circulation character which blow the gale towards east .The gale disaster not only became more intense heat depletion rate of the flock and formed frozen disaster and also made the flock lost .We should take the defensive measure actively during the animal husbandry transferring to make the least loss.
