| 该文利用铜仁市西5县5个国家站2019年自动与人工观测的日照数据，对自动观测和人工观测在时间和空间上的差异进行了对比分析。分析发现：自动与人工观测年日照最高值均出现在沿河，最低值则出现在印江和德江；在同一观测环境中，各县2种观测方式得到的年日照时数差值不大，相对差值在6.5%范围内；不同季节的2种观测方式的日照时数多寡分布规律一致，不同月份日照时数多寡变化规律基本一致；从空间分布上对比分析2种观测方式得到的月日照时数，各月最大值的变化趋势比较一致。 |

| Abstract: |
| The paper analyzed the differences between automatic observation and artificial observation in time and space based on the sunshine data of five national stations in western counties at Tongren City in 2019.The results show that the maximum sunshine value of automatic and artificial observation occurs in Yanhe and the lowest value occurs in Yinjiang and Dejiang. In the same observation environment, the difference of annual sunshine duration obtained by the two observation methods in each county is not large, and the relative difference is within 6.5%. The distribution law of sunshine duration of the two observation methods in different seasons is consistent, and the change law of sunshine duration in different months is basically consistent. Comparing and analyzing the spatial distribution of monthly insolation between the two observation methods, the variation trend of monthly maximum is consistent. |
