摘要
依照松突圆蚧Hemiberlesia pitysophila Takagi的灾害特点,将广东省松突圆蚧发生区以县级为单位进行了发生区划,并构建了基于气象因子的灾害程度判别模型,依据该模型结合林分构成和林业经营特点研究了松突圆蚧发生区划,将广东省松突圆蚧发生区划分为轻度分布、中度发生和重度危害3个区域,并提出了各区域松突圆蚧防治策略。
According to the characteristics of hazard caused by H.pitysophila in Guangdong Province,a county-level occurrence regionalization of H.pitysophila was conducted and a disaster discriminating model was built based on the meteorological factors.According to the model as well as features of fo-rest structure and management the county-level occurrence regionalization was studied.The counties were divided into 3 zones,ie light occurrence zone,moderate occurrence zone and severe infested zone.The regional control measures against the pest were proposed.
