摘要:

 宣恩地处长江中上游,具有山地、水系、气候等方面的区位特殊性,利用1959 ~ 2009 年的观测资料,分析宣恩平均温度、平均最高温度、平均最低温度和平均日较差的变化趋势和特点。结果表明,近51 a 来宣恩平均温度( 除冬季) 1980 年代中期前降温,后增温,冬季呈持续增温趋势。最高温度与平均温度变化趋势相似,不同的是1980 年代中期以后的增温幅度要大于平均温度。不同于平均温度和最高温度,最低温度呈持续升高趋势。年平均日较差先减小后增加,冬、夏季日较差减小,而春、秋季却呈增加趋势。分析认为,小城镇的增温现象不可忽视,宣恩最低温度变化受人为影响更加显著。

Abstract:

 Xuan’en is located in the middle and upper reaches of the Yangtze River,it has a special character with mountain,water and climate system. Based on the meteorological data during 1959 - 2009,the trends of average air temperature,average maximum and minimum temperature,average temperature daily range in recent 51 years in Xuan’en were analyzed in this paper. The results show that the annual mean temperature decreased before the middle of the 1980s and then increased,and continued warming occurred in winter in recent 51 years. Though the trend of maximum temperature was similar to average temperature,but the increase of the maximum temperature after the middle of the 1980s was more significant than that of average temperature. The minimum temperature was quiet different with continuously warming trend. The variation of average temperature daily range decreased in summer and winter,increased in spring and autumn. People should pay more attention in the impacts of temperature increasing in small city,and human activity’s influence was more evident on increase of the minimum temperature.

Key words: mountain region, temperature change, Mann - Kendall test, Xuan’en
