摘要
利用1959—2012年长三角地区20个台站观测的年平均温度,采用线性倾向估计、M-K突变检验和累积距平等方法研究了该地区温度的变化特征,结果表明,与全球变暖停滞一致,长三角地区的温度也存在变暖趋缓的现象。其中北部沿江台站温度在1997—1999年发生突变,南部内陆台站突变偏晚2～3年,在2000—2001年发生突变,沿海台站均在1997年发生突变。受城市化效应的影响,徐家汇和杭州站年平均温度发生突变的时间相比于周边台站偏早3～4年,并没有呈现出明显的变暖停滞的现象。
Based on the observed temperature data of 20 stations in Yangtze River Delta region,we analyzed the char- acteristics of average temperature using linear trend estimate, Mann-Kendall test and cumulative anomaly test. Warming hiatus did exist in Yangtze River Delta region, which was consistent with global wanning hiatus.The tem- perature of the stations along the Yangtze River in the north was abruptly changed from 1997 to 1999.And the tem- perature of the stations along the Yangtze River in the south was 2 to 3 years later, from 2000-2001.The temperature of the coastal stations were all abruptly changed in 1997.Due to the urbanization effect, the change of average temper- ature of Xujiahui and Hangzhou stations were 3 to 4 years earlier than the surrounding stations, and there was no ob- vious warming hiatus in both stations.
