摘　　要：文章利用1992-2011年南京市酸雨资料和油菜的产量资料,分析了酸雨对南京市油菜产量的影响,结果发现:油菜全生育期降水pH值与产量呈正相关,其中1-4月的降水pH值对油菜后期产量形成影响最显著。基于月降水pH值,建立了油菜产量的多项式回归模型,通过反演,发现该模型对产量模拟和灾损评估具有较好效果。The correlation analysis was processed among the data of Nanjing acid precipitation from 1992 to 2011 and oilseed rape yield,the results showed that there was a positive correlation between pH value of precipitation anomaly during whole growth period and the yield,while precipitation from January to April had a significant affect.Then,polynomial regression model was established based on pH value of precipitation of January,March and April,and by inversion calculation,we found that the model had good effects on yield simulation and disaster damage assessment.
