| 摘 要： | 为了消除城市化进程对旧站地温的影响,运用数理统计方法对康乐县新旧地面气象观测站2012年1-12月同期0-20 cm地温平均值、方差及相关性进行F、T、t检验,对新旧2站数据差异显著的地温,利用最小二乘法进行最佳线性拟合,建立2站地温订正方程。结果表明：整体而言,新站与旧站0-20 cm地温均存在负温差,旧站地温较新站的偏高,大多数月份差值较小,资料连续性较好,但2站地温差值变幅较大。地温差异显著的1月和10月2站地温资料呈显著线性相关,经订正后的新旧站资料基本重合。

| Abstract: | In order to eliminate the impact of urbanization on the ground temperature of old meteorological observation station,the mean,variance and correlation of 0-20 cm synchronous ground temperature from January to December in 2012 in the old and new meteorological stations of Kangle were analyzed and tested by using mathematical statistic and F,T and t test methods,and the line regression equations of the obvious difference ground temperature between the old and new stations were fitted by using the least square method.The result showed that the difference of 0-20 cm ground temperature in the old and new stations was negative as a whole,that is to say,the ground temperatures in the new station were higher than those in the old station,and the differences in most of months were small.Although the data of ground temperature had a good continuity,the fluctuations of the difference between the old and new stations were large.The obvious ground temperature difference between the new and old stations in January and October appeared a significant linear correlation,and the ground temperatures between the revised data and the data of the new station were basic coincidence. |
