摘　　要：笔者在安吉县对主要竹林害虫进行了发生类型区划研究。按害虫的发生频次高低对常灾区、偶灾区、安全区的概念作了明确阐述并制定了划分标准,然后以竹区村为单位根据毛竹、杂竹面积、出笋大小年,竹林占有林地百分比、竹林分布和农业气候、地形、地貌等因子,采用逐项打分计分定类的方法按村区划全县竹虫发生类型,经验证明总正确率达85%以上。The division of occurrence type of the main bamboo insects was studied at Anji county,Zhejiang province.The occurrence type was divided into 3 regions of frequent,occasional and safety region based on the actual occurrence frequency of the bamboo insects.The division standard was made and described.
