摘  要：
为了解全球变暖下南昌地区气温及降水的变化趋势,采用时间序列分析方法和变差系数法分别对南昌地区近55年的气温及降水进行分析。结果表明:近55年来南昌地区的平均气温呈上升趋势,倾向率为0.016 4℃/a,气温年较差呈下降的趋势,倾向率为-0.052 3℃/a;极低气温变化趋势较极高气温变化趋势显著,气候倾向率分别是0.552℃/(10 a)和-0.009 5℃/(10 a);综合分析降水变化不明显,总体呈略增加趋势。由此推断21世纪初南昌地区降水年际变化相对稳定。

摘  要：
In order to understand the changing tendency of temperature and precipitation in Nanchang area under global warming circumstance,using time-series methods and coefficient of variation,the temperature and precipitation in Nanchang in recent 55 years were analyzed.The results showed that: the average temperature presents an upward trend,its tendency rate was 0.016 4 ℃/a,the annual temperature range presents a downward trend,its tendency rate was-0.052 3 ℃/a.The change tendency of extreme low temperature was more significant than that of the extreme high temperature,the two climate tendency rates was 0.552 ℃/10a and-0.0095 ℃/10 a.The change of precipitation was analyzed comprehensively,the result showed that general changing tendency was not significant and showed a slightly rising tendency.So it may be concluded that annual changes of precipitation would in the state of relative stability in the early 21st century in Nanchang area.
