新疆大风灾害灾度和危险度分析

Disaster Degree and Risk Degree of Wind Disasters in Xinjiang

对新疆1980年到2000年的大风灾害信息和各地区县、市的统计年鉴及105个气象站53a的资料进行分析。新疆的大风灾害事件多出现在夏季的5月和6月,这时候也正是新疆大风最多的时节。灾度分析得出新疆大风灾害均为轻灾,救灾以县级为主;并且各地区出现的最大灾度跟各地区出现的大风灾害事件的次数大体上一致,只有石河子市、巴州地区出现了不一致的现象。危险度分析得出,新疆没有极重度危险地区,大部分属于中度危险地区。通过对新疆的大风灾害的灾度和危险度分析,发现两种方法的分析结果存在差异并加以讨论,为各地州、县、市政府管理部门提供防治大风灾害的参考依据。

Analysis on wind disaster data in 1980-2000 from literature,statistical yearbook,and on weather data for 1957-2010 from 105 weather stations in Xinjiang disclosed that wind disasters mainly occurred in May to June when strong wind days is the most too.The degree of wind disasters in Xinjiang are mainly the mild disaster and county government will principally provide disaster relief.The wind disaster degree and strong wind days is coherent in each district of Xinjiang except for Shihezi and Bazhou districts.There is no extremely severe risk area in Xinjiang and most areas in Xinjiang belong to moderate risk area.It is found out that the analyzing results based on disaster degree and on risk degree of wind disasters are different,and the reasons are differentiated too.The results will provide theoretical basis for local government to prevent from wind disasters.
