| 摘 要： | 运用数量化理论对杨树天牛发生区内不同林分结构、树种组成和气候因素下的发生量预测，表明林分结构。温湿系数和抗性指数对杨树天牛的发生量影响显著。抗性指数更容易反映不同林分树种配置下对杨树天牛的抗性差异。

| Abstract: | Within the outbreak region of poplar longicorn the occurring number of poplar longicorn in different stands with different structure, composition and climate factors were approached by the theory of quantification. Stand structure, stand resistance index and temperaturehumidity coefficient were main factors affecting the occurring number of poplar longicorn, especially the stand resisance index. |

| Keywords: | poplar longicorn occurring number prediction theory of quantification resistance index |
