摘要:
利用资源县1961~2017年逐日气温观测资料，应用线性倾向估计、t检验及M-K突变检验法对资源县57年冬季气候变暖特征进行了分析。结果表明：近57年资源县冬季、年平均气温上升趋势显著，线性倾向率为0.276、0.19℃/10a，冬季气候变暖趋势明显，对全年气候变暖贡献较大；2月份平均气温显著上升，线性倾向率为0.419℃/10a，对冬季变暖贡献较大；极端最低气温上升趋势更为显著，线性倾向率为0.448℃/10a，对冬季增温影响最显著；冬季平均气温的突变点发生在1996年；20世纪1960~1980年代为冬季低温期，冷冬大多出现在1980年代之前，暖冬1990年代之后呈明显增加趋势。
Abstract:
Based on the daily temperature data from 1961 to 2017 in Ziyuan County, the characteristics of winter climate warming in Ziyuan County in 57 years were analyzed by means of linear tendency estimation, t test, and M-K mutation test. The results show that in the past 57 years, the average winter and annual air temperature in Ziyuan County have increased significantly, with linear tendency rates of 0.276 and 0.19 per decade, respectively. The climate warming trend was obvious in winter, contributing greatly to the annual climate warming. In February, the mean temperature increased significantly, and the linear tendency rate was 0.419 per decade, which contributed greatly to the winter warming. The abrupt change of winter mean temperature occurred in 1996; the 1960s-1980s was a low-temperature period in winter, and the cold winter mostly appeared before 1980s, while the warm winter showed an obvious increasing trend after 1990s.
