| 摘 要： | 利用四川省自动与人工地温对比观测数据对0～320cm地温进行逐层对比分析,发现自动与人工观测的逐层地温差异不同,地表温度和浅层地温自动观测数据比人工观测数据偏高。自动与人工观测数据一致率最高的是160cm地温,达到21%,一致率最低的是80cm地温,仅为6.2%;80cm地温的差值绝对值大于2℃的百分率最高,接近70%左右;地温年值正差异最大的出现在红原,自动比人工偏大达8.32℃。

| Abstract: | Analysed the difference of 0 cm to 320 cm ground temperatures between the data which observed by automatic and manual in parallel. The results indicated that the ground temperatures were different per layer, and the surface temperature and shallow ground temperatures which observed by automatic was higher than manual. The highest consistent rate of automatic and manual observation data is 160 cm ground temperature, reaching 21%, and the lowest consistent rate is 80 cm ground temperature, only 6. 2%, the absolute difference of 80 cm ground temperature is greater than 2 centigrade, the percentage is close to about 70%, the most difference of ground temperature value was in Hongyuan, which automatic observation was higher up to 8. 32℃ than the man-boserved. |
