摘　　要：根据2003—2012年上海地区树木病虫害发生程度和同期气象资料,应用数理统计分析方法对病虫害发生的内外因素进行了分析。结果表明:梨锈病发生程度与3—4月份中旬日平均相对湿度≥75%日数的相关系数为0.8924,梨小食心虫发生程度与6—8月份日平均相对湿度≤80%日数的相关系数为-0.91 50,桃蛀螟发生程度与3—6月份降水日数的相关系数为-0.941 5,樟巢螟发生程度与8月26日至10月中旬降水日数的相关系数为0.7755,扁刺蛾发生程度与7月中旬至9月上旬日平均相对湿度≤72%日数的相关系数为0.8765,杨扇舟蛾发生程度与4月中旬—9月降水日数的相关系数为0.8928,黄杨绢野螟发生程度与6月16日—10月上旬降水日数的相关系数为0.9035。并对有害生物的内在因素、寄主植物因素和人为因素进行了简要分析。According to the incidence survey of tree disease and insect pest in Shanghai area between 2003--2012 and the meteorological data in the same periods, factors influencing the tree disease and insect pest were analyzed by mathematical statistics. The results showed that the correlation coefficient between the incidence of pear rust and the clays from March to mid April at 75% or more of daily average relative humidity was 0. 8924, the correlation coefficient between the incidence of oriental fruit moth and the days from June to August at 80% or less of daily average relative humidity was -0. 9150, the correlation coefficient between the incidence of peach borer and the rainy days from March to June was -0. 9415,the correlation coefficient between the incidence of Orthaga olivacea and the rainy days from August 26 to mid October was 0.7755, the correlation coefficient between the incidence of Thosea sinensis and the days from mid July to early September at 72% or less of daily average relative humidity was 0. 8765, the correlation coefficient between the incidence of Clostera anachoreta and the rainy days from mid April to September was 0. 8928,and the correlation coefficient between the incidence of Diaphania perspectalia and the rainy days from June 16 to early October was 0. 9035. Also the pests＇ internal factors, host plants＇ factors and human factors were briefly analyzed.
