摘要
利用陕北地区1959～2009年50年以来延安、榆林、定边、吴旗、横山、绥德等6个气象站点的逐年气温、降水资料,通过年平均气温距平变化、非参数Mann-Kendall检验方法,对陕西省陕北地区气温年平均温度变化、年平均最高气温变化、年平均最低气温变化特征进行了分析,揭示了陕北地区近50年来气温变化趋势,并且结合陕北地区旱涝灾害等级,分析了陕北地区气温变化对陕北旱涝灾害的影响。
It adopts the temperature,rainfall data in the meteorological stations of Yan＇an,Yulin,Dingbian,Wuqi,Hengshan,and Suide in Shanbei region year by year from 1959 to 2009.Analyzing on annual average temperature variation,annual average maximum and minimum temperature variation and minimum temperature variation characteristic in Northern Region of Shaanxi Province,and it is by means of the test method of average temperature departure variation and nonparameteric Mann-Kendall,which reveals the variation trend in recent 50 years in Shanbei,combined with drought and flood grade in Shanbei,analyzed the impact which is occurs by the temperature variation upon drought and flood damage in Shanbei.
