Pest disasters are serious threats faced by the forest ecosystem of China. This study selected 316 research papers on forest pest disasters with the selection criteria that primary data of the research were completely obtained from ground survey. We compiled the time of occurrence, location, affected area, and intensity of each forest pest disaster (FPD) event. Then, using Meta-analysis on these records, we depicted the spatial and temporal variability of forest pest disasters in China. A total of 962 FPD records were compiled. These records involved 299 counties in China and covered a temporal range from 1985 to 2018. The results showed that there were 242 county-times of serious FPD events during 1985-2018 with an annual mean of 7.1 county-times. From 1985 to 2005, the annual county-time number of serious FPD events increased at 0.4 county-times per year, but the upward trend was replaced by a decline of -0.6 county-times per year from 2005 to 2018. Spatially, there were more FPD events in the Wuyi Mountains in southeast China and the Qilian Mountains in northwest China compared to other regions. The frequency of serious FPD events exhibited a declining trend from the southeastern coast of China to the northwestern inland region. The Wuyi Mountains area was the most serious FPD region of China. Meteorology factors were considered the primary factor that influenced the FPD. The interannual fluctuation of FPD frequency was negatively correlated with winter temperature of the previous year in the southern part of the semi-arid area and the warm temperate semi-humid area; while it is negatively correlated with spring temperature in the north sub-tropic area and the central sub-tropic area in the south.
