摘要
基于山西省106个气象站的气温数据,通过分析气温要素的累积距平、年代变化、季节变化和空间分布,研究了山西省1960-2005年气温要素的时空变化趋势。结果表明,从20世纪80年代后期起,山西省平均气温呈持续增加的趋势。在空间分布上,全省气温西南部气温增加趋势大于东北部的趋势,而且增加趋势由西南部向东北部递减。气温各季节变化趋势不同:全省春、冬两季气温变化一致;秋季升温趋势明显,但在2000年之后增温趋势有所回落;而夏季气温呈先增加后降低的趋势。此外,人类活动影响了温度的分布,且气温对全省干旱情况也有影响。
Based on the data from 106 weather stations which are located in Shanxi Province,the temporal and spatial trend of temperature change was investigated by analyzing the accumulative anomaly,interdecadal variability,seasonal variability and spatial variability.Results show that the mean temperature of Shanxi Province continues to increase from the late 1980s.For the spatial distribution,the increment of mean temperature in the southwest Shanxi Province is greater than that in the northeast Shanxi Province.Furthermore,the trend of the increment decreases gradually from the southwest to the northeast.Seasonal trends of temperature are different.The temperature change trend in the spring is consistent with that in the summer season.A noticeable increasing trend has shown in the autumn season,although the trend descending after 2000.The temperature trend in summer increases first and then decreases.In addition,human activities affected the distribution of temperature,and temperature also affected drought conditions in total.
