Based on the observed daily sunshine hours of 59 national meteorological stations from 1961 to 2018 and daily temperature data of 32 microclimate meteorological stations for facility agriculture from 2008 to 2018 in Shandong Province, this study analyzes the spatial and temporal distribution and trend of continuous overcast skies and their influence on the temperature condition for facility agriculture in the production season using linear regression, Mann-Kendall test, and inverse distance weighted (IDW) interpolation methods. The results are as follows. 1) Temporally, the total times and days of continuous overcast skies increase by 1.7 times·a-1 and 6.5 d·a-1 in the past 58 years, respectively, and the mutation of the total times occurs in 1999. 2) Spatially, the total times and days of overcast skies increase from the northeast to the southwest of Shandong Province. The increase is much more obvious in Liaocheng and Dezhou with the total times and days at a single station increasing by more than 0.06 times·a-1 and 0.2 d·a-1. Moreover, the trend passes the significance test at 0.05 level in the 15 and 13 stations such as Liaocheng. 3) The temperature dropping rate in facility agriculture increases as the days of continuous overcast skies increase. 4) For the same days of continuous overcast skies, the dropping rate of the average and the minimum temperature in spring and autumn is greater than that in winter, and the reason may be that the temperature in spring and autumn is basically higher than that in winter, which is more likely to cause dramatic changes in temperature. The results can provide theoretical support for relevant departments to study the planting layout and to guide production and disaster prevention and mitigation for facility agriculture.
