摘要
基于山西省16个气象站的数据,对1958~2012年的气温、降水和旱涝灾害的时空分布规律及其它们之间的内在关系进行了分析。结果表明:1958~2012年,山西省气候趋于暖干化,气温波动上升,而降水却波动下降;旱灾发生的概率大于涝灾,而且旱灾概率有所上升;山西省中部和南部的旱灾次数多于北部,南部的灾害等级高于北部,北部旱涝灾害发生频率低于中部和南部。
Based on the data of 16 meteorological stations in Shanxi province,the temporal and spatial distribution of temperature,precipitation,drought and flood disasters from 1958 to 2012 and their internal relations were analyzed. The results show that the climate of Shanxi province tended to warm and dry from 1958 to 2012; the temperature fluctuation rose,but the precipitation fluctuation decreased. The probability of drought was greater than that of flood,and the probability of drought increased. The droughts in central and southern Shanxi province were more frequent than that in the north. The disaster level of southern Shanxi was higher than that in the north.The frequencies of droughts and floods in the south and central were higher than the north part.
