| 摘 要： | 松毛虫种群数量的消长与松毛虫内在遗传特性有关，但气象等外界因子也影响着种群数量的变化。为准确掌握松毛虫种群基数，做好预测预报，作者应用距平符号法，利用前4a气象因子与松毛虫发生量的关系，进行了松毛虫动态预测，准确率100％。

| Abstract: | The population fluctuation of pine caterpillar was correlated with its inherent hereditary (characteristics).But some external factors such as weather also influenced the population fluctuation.So anomalous sign was used in the forecast of pine caterpillars' dynamics with the weather data in the last 4 years.The accuracy was 100%. |
