摘　　要：为全面掌握红寺堡酿酒葡萄根系层冬季土壤温度的变化特征,利用同心气象站1961—2015年冬季(12月—次年2月)0、10、15、20、40 cm逐日平均土壤温度资料,对其变化规律分析。结果表明:酿酒葡萄根系层冬季土壤温度垂直变化特点是随着深度增加呈升高趋势;55年冬季0~40 cm平均土壤温度日变化趋势一致,先降后升,最低值在-7.3^-3.4℃之间,出现时间在1月13—25日;55年冬季土壤温度年际变化呈显著上升趋势;0~20 cm各层气候变化倾向率在0.432~0.604℃/10 a,0、5、10、20 cm土壤温度分别在1989年、1989年、1989年、1984年发生了突变,突变前均为冷期,突变后均为暖期;55年冬季土壤温度年代际变化总体以升温为主,21世纪10年代较21世纪00年代呈下降趋势。To study winter soil temperature changes in root layer of Hongsibu wine grape,the variation law was analyzed by using daily average soil temperature data of 0,10,15,20 and 40cm (December to next February) from 1961 to 2015 of Tongxin weather station.The results showed that soil temperature in the root layer increased with the increase of depth;the daily average variation in 0-40cm soil layers of the 55years had the same trend of first decreasing and then increasing,with the lowest value ranging from -7.3℃ to -3.4℃ and the appearance time between January 13 and January 25.The inter-annual variation had a significant increasing trend in the 55 years.In 0-20cm,climate change tendency rate of each layer was between 0.432-0.604℃/10a. The soil temperature of 0,5,10and 20cm respectively had a mutation in 1989,1989,1989and 1984,all of them were cold periods before mutation,warm after mutation.The inter-decadal variation was mainly temperature rising,but the 2010s showed a declining trend compared with the 2000s.
