中文摘要：

利用南靖站1981～2010年的平均气温、降水量、日照时数和蒸发量,采用回归线性趋势分析、累积距平、信噪比等方法对南靖县近30a的气候特征进行了分析.结果表明：1981～2010年南靖县气温以0.32℃/10a呈显著上升趋势,气温在1997年前后发生突变.降水量以-33.4mm/10a呈减少趋势,但减少趋势并不显著.日照时数以21.7h/10a呈增加趋势,但整体上升趋势也不显著.蒸发量以134.2mm/10a趋势显著增加,在1995年左右发生突变.

英文摘要：

Based on the annual average temperature, precipitation, sunshine duration and evaporation of Nanjing station during a series （1981~2010） , the climate characteristics were analyzed by the linear regression trend, the cumulative anomaly, signal to noise ratio and other statistical method. The results showed that the average temperature had a significant warming trend in Nanjing from 1981 to 2010 with a walTning rate of about 0.32℃/10a. The abrupt change of temperature occurred in 1997. The precipitation decreased with a rate of about -33.4mm/10a, but the trend was not obvious. The sunshine duration increased with a rate of about 21.7 h/10a, but the trend was not obvious. The evaporation significantly increased with a rate of about 134.2mm/10a, the abrupt change of evaporation occurred in 1995.
