摘要: 为了掌握榆社县近50 年气温变化规律,为生态农业扶贫开发项目开展提供理论依据,利用1961—2010 年榆社县气温资料,采用线性倾向估计、相关系数分析、滑动平均,Mann-Kendall 检验等方法,对气温变化的特征及变化趋势进行了分析。结果表明:近50 年来榆社县年平均气温呈升温趋势,气温倾向率0.08℃/10a。年平均最高气温、冬季平均气温、年极端最高气温、春季平均气温年际变化均呈升温趋势,气温倾向率分别为0.30℃/10a、0.28℃/10a、0.21℃/10a 和0.12℃/10a;而年极端最低气温、夏季平均气温、年平均最低气温、秋季平均气温却呈降温趋势,气温倾向率分别为-0.30℃/10a、-0.04℃/10a、-0.03℃/10a 和-0.02℃/10a。升温趋势显著时段主要出现在20 世纪90 年代,而降温最明显时段出现在20 世纪80 年代;年平均日较差变化呈增高趋势,90 年代达到最大值。榆社县气候变暖主要是白天增温明显,尤其体现在冬、春季,气温在20世纪80年代中后期至90年代后期有较明显的暖突变。

Abstract: In order to master the characteristics of temperature variation of Yushe county, providing theoretical basis for carrying out scientific research of the poverty alleviation by ecological agriculture project, based on the temperature data of Yushe county from 1961 to 2010, the variation trend and characteristics of temperatures change in Yushe county were analyzed by adopting such statistical methods as linear tendency estimation, correlation coefficient analysis, moving average and Mann-Kendall test. The results showed that: The temperature had a rising tendency in recent 50 years, the tendency rate of temperature change was 0.08℃/10a. The annual average maximum temperatures, winter average temperature, annual extreme maximum temperatures and spring average temperature were in the increasing trend, and their tendency rate are 0.30℃/10a, 0.28℃/10a, 0.21℃/10a and 0.12℃/10a, respectively, while the annual extreme minimum temperatures, summer average temperature, annual average minimum temperature and autumn average temperature were in the decreasing trend, and their tendency rate were -0.30℃/10a, -0.04℃/10a, -0.03℃/10a and -0.02℃/10a. The period of evident rising was the 1990s, and the cooling trend was in the 1980s, annual average daily range of temperature presented increasing trend, and reached to the maximum in the 1990s. The largest contribution to the climate warming was rising of daytime temperature in winter and spring, and the temperature had an evident warming mutation in the middle-late 1980s to the late 1990s.
