摘　　要：本文利用同心气象站2004—2015年冬季(12月~翌年2月)0、5、10、15、20、40 cm逐日平均地温和日最低气温、日平均气温资料,对地温、气温相关关系进行分析,用线性回归建立土壤温度预报模型。结果表明:酿酒葡萄根系层土壤温度与最低气温的相关性大于其与平均气温的相关性;将2016年冬季最低气温代入20 cm、40 cm地温预报模型得出平均绝对误差在0.8~1.3℃,可用于冬季冻害地温预报服务。Based on topsoil ground temperature of 0 cm, 5 cm, 10 cm, 15 cm, 20 cm and 40 cm, as well as daily minimum air temperature and daily mean air temperature of Tongxin weather stations from 2004 to 2015 in winter （December to next February）, correlation between ground temperature and air temperature was analyzed, and the ground temperature prediction model was established by using linear regression. The results showed that there were better linear correlations between ground temperature and minimum air temperature; prediction model could be used for ground temperature forecast in winter freezing damage, while daily minimum air temperature in winter of 2016 were back substituted to 20 cm and 40 cm ground temperature prediction model, the average absolute error was 0.8-1.3 ℃.
