摘　　要：文章对2018年1~12月荆门国家气象观测站的暗筒式日照计与FS-RZ1型光电式自动日照仪人工和自动观测的日照时数进行对比分析。结果显示,二者日照时数全年累计差值较小,逐日数据具有非常好的相关性,差值分布较均匀,造成部分时间差值较大的原因主要是不同仪器时间分辨力和感光灵敏度的不同。This paper compares and analyzes the sunshine duration observed manually and automatically by the dark tube sunshine meter and the FS-RZ1 photoelectric automatic sunshine meter of Jingmen National Meteorological Observation Station from January to December in 2018.The results show that the annual cumulative difference of sunshine duration between the two meters is small and the daily data has a very good correlation and the difference is evenly distributed.The main reason for the large time difference is the difference of time resolution and sensitivity of different instruments.
