摘要
利用气候倾向率、标准偏差方法，划分基准年，研究1952～2010年地面、耕作层温度变化特征。结果表明：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、0．304、0．206℃／10年。冬季、春季对年平均地面温度升高的贡献最大，气候倾向率分别为0．535、0．521％／10年；夏季、秋季贡献较小，气候倾向率分别为0．223、0．291℃／10年。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。
The variation characteristics of the surface and plow layer temperature during 1952--2010 in west region of Liaoning Province were studied using the climate tendency rate and standard deviation based on the reference windows of data. The results showed that the annual mean surface temperature and the mean temperatures of the surface and plow layer in growing season were all with increasing tendency. The climate tendency rates were 0. 395 ~/10a, 0. 304 ~C/lOa and 0. 206 ~C/10a respectively. The fast increasing rate occurred in winter and spring, with the climate tendency rate of 0.535 ~C/10a and 0. 521 ~/10a respectively. Slow increasing rate occurred in summer and autumn, with the climate tendency rate of 0. 223 ~C/10a and 0. 291 ~C/10a respectively. The recording in the third window was with the fastest in- crease among the data. These results can provide the reference for the structural readjustment of agricultural production and the ecological en- vironment governance and so on in this region.
