Analysis on the Change Trend of Ground Temperature in Maize Growing Season in Chaoyang Region of Western Liaoning

利用气候倾向率、距平分析、基准年等统计方法,分析辽宁西朝阳地区近60年玉米生长季耕层地温变化特征。结果表明,辽宁西朝阳地区近60年玉米生长季耕层地温呈上升趋势,气候倾向率0.206℃/10年。玉米生长季耕层地温不同基准年间变化明显不同,第Ⅲ基准年上升趋势最明显,气候倾向率为0.642℃/10年。

Based on the climatic tendency, anomaly analysis and base year, the change features of ground temperature in the growing season of maize in Chaoyang region of western Liaoning were analyzed. The results showed that the ground temperature of the plow layer in Chaoyang region of western Liaoning increased during the last 60 years, and the climatic tendency was 0.206 ℃/10 a. The change trend of ground temperature in different growing years was significantly different from that in base year, and the trend of the third year was the most obvious. The climatic tendency was 0.642 ℃/10 a.
