摘　　要：对黑龙江大兴安岭地区6个气象台站的气象资料进行整理和分析,从中筛选出影响虫害发生面积的7个气象因子,并分别对其做相关分析,研究了气象因子对种群数量的影响,模拟虫害发生面积预测方程。结果表明:与虫害发生面积密切相关的因子有年积温(≥10℃)、年降水量和干燥度;虫害发生面积同三者的Pearson相关系数分别为0.701、-0.814和0.937;通过分析极端气候现象对虫害面积的影响,发现春季阴雨和虫害面积存在显著的正相关关系,冬冻和春寒对虫害发生面积并没有直接的影响。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.
