林分主要因子与花布灯蛾危害关系的研究

Study On the Relationship Between the Main Factors of Stands and Damage Degree of Camptoloma interiorata(Walker)

为有效防治花布灯蛾危害,对花布灯蛾危害程度与林分因子关系进行研究,采取2000—2001年吉林省东丰县、辉南县、梅河口市、磐石市在不同危害程度林分(小班)及相应林分主要因子,运用粗糙集理论方法分析,结果表明:对花布灯蛾发生影响的林分因子权重排序依次为林分面积、蒙古栎占林分树种组成、林分郁闭度、林分平均树高、林龄、林分平均胸径。

For the sake of effective controlling damage of Camptoloma interiorata(Walker),the relationship between the main stand factors and damage degree of C. interiorata were studied with the information of damaged degree in different stands and the main factors among Dongfeng,Huinan,Meihekou,Panshi Jilin province during 2000—2001. The rough set theory method was used. The results showed that the weight sort sequence queuing of the stand factors was the forest area,the percentage composition of Quercus mongolica,the crown density,the average tree height,the stand age,the average diameter at breast height for important influence factors of C. interiorata.
