| 摘 要： | 应用数量化理论Ｉ找出影响杨树林分受天牛危害的主要因子，并以此从林分结构及生长动态和天牛虫害的数量动态方面进行分析，克服了以往仅考虑虫害数量动态的缺点，比较客观地反映了生物群体之间的相互制约与相互影响的关系，合理地将危害状划分为五类，为综合治理提供了理论依据。

| Abstract: | Main factors affecting the damage to poplar stands by poplar longicorn were approached by quantitative theory I considering the dynamics of stand structure and growth as well as the population fluctuation of poplar longicorn. Interaction between different biological populations was studied. The damages could be divided into 5 categories using the method above. |
