摘要:

利用气候倾向率、标准偏差方法,划分基准年研究1952—2010年辽宁西部地面、耕作层温度变化特征。结果表明:辽宁西部年平均地面温度、农作物生长季地面和耕作层温度呈升高趋势,气候倾向率分别为0.395℃/10a、0.304℃/10a、0.206℃/10a。冬季、春季对年平均地面温度升高贡献最大,气候倾向率为0.535℃/10a、0.521℃/10a;夏季、秋季贡献较小,气候倾向率为0.223℃/10a、0.291℃/10a。第Ⅲ基准年升温最剧烈。研究结果可为该地区农业生产结构调整、生态环境治理等提供参考。

Abstract:

The variations of temperatures at the surface and plow layer during 1952-2010 in the west region of Liaoning province were studied by methods of a climate tendency rate, a standard deviation and a baseline year. The results show that the annual mean surface temperature, and the mean temperature of the surface and plow layer in the growing season are in increasing trends, and the climate tendency rates are 0.395 ℃per decade, 0.304 ℃per decade and0.206 ℃per decade respectively. The higher increasing rates occur in winter with 0.535 ℃ per decade and spring with 0.521℃ per decade, and the lower increasing rates are in summer with 0.223 ℃ per decade and autumn with 0.291℃per decade respectively. Warming in the third baseline year is most significant. This study could provide the references for the structural readjustment of agricultural production and the ecological environment improvement, etc. in this region.
