Abstract: Based on the meteorological data of six observatories in the Great Xing’an Mountains of Heilongjiang Province, a total of seven meteorological factors affecting the occurrence area of forest insect pest were selected, and their correlations were analyzed, aimed to investigate the effects of meteorological factors on the insect pest population quantity, and to build the forecast equation of the insect pest occurrence area. The results showed that the meteorological factors closely related to the insect pest occurrence area were the yearly accumulated temperature of ≥10℃, yearly precipitation and dryness, with the Pearson coefficient being 0.701, -0.814 and 0.937, respectively. The analysis on the relationships between extreme climate phenomena and insect pest occurrence area suggested that the overcast and rainy days in spring had a significant positive correlation with the insect pest occurrence area, while the coldness in winter and spring had no direct effect on it.
