| 摘 要： | 通过Z指数法和降水资料对昌吉地区8个国家级气象观测站37a(1971—2007年)的旱涝变化趋势和时空分布特征研究,发现昌吉州各地降水和旱涝变化具有一致性.20世纪70年代以来,各地具有由偏旱转为偏涝的趋势,其中,西部地区的偏涝速度最快,东部地区的偏涝速度最慢.各地出现干旱的频率高于雨涝的频率,其中,西部出现干旱频率最大,东部最小;相反,西部出现雨涝的频率最小,东部最大.

| Abstract: | Drought is one of the major natural hazards in Changji areas.By using the method of Z-index and precipitation data of 37 years(from 1971 to 2007)of 8 representative meteorological stations in Changji areas,this paper studies the change of the drought and flood tendency and the distribution characteristics.The results indicate that the precipitation and characteristics of drought and flood in Changji areas is consistent,and the tendency is changing from drought to flood after mid-1970s,which is most significant in west and least significant in east.Frequency of drought in Changji areas is higher than that of flood,and frequency of drought is higher in west than in east,while frequency of flood is lower in west than in east. |
