| 摘 要： | 对广东省多年的马尾松毛虫林间发生面积和气候因子进行主成分分析和逐步回归分析，研究气象因子对马尾松毛虫种群的影响，模拟广东省马尾松毛虫发生规律方程。分析结果表明：在年气象因子中，主成分因子是年总降雨量，但其与马尾松毛虫年发生面积的相关性不显著；在月份气象因子中，3月的月均温度、4月和6月的月均湿度、7月的月均温度和月总降雨量、10月的月均温度和月总目照时数与马尾松毛虫发生面积具有显著的相关关系。

| Abstract: | The author analyzed the investigation areas of massonpine caterpillar(Dendrolimus punctatus Walker) occurred on the forestland in Guangdong province and the meteorological observation data of there by principal component analysis and stepwise regression analysis,and found out the relations between meteorological factors and population dynamics of the caterpillar and got the population dynamics rule of the caterpillar in Guangdong province.The results showed that the main influence factor among annual weather factors is year rainfall,but it has no obvious relevance with the annual area of the caterpillar occurred;Among the monthly climatic factors,the average temperature of March,the average humidity of April and June,the average temperature and total rainfall of July,the average temperature and monthly sun shine hours of October have obvious relevance with annual occurring rate of the caterpillar. |
