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。
Based on the acid rain data of Nanjing and the yield data of rape from 1992 to 2011, the article analyzed the influence of acid rain on the yield of rape in Nanjing. The results showed that: the precipitation of rape during the whole growth period had a positive correlation with the yield of precipitation, of which precipitation pH from January to April The value of the late rapeseed yield the most significant impact. Based on the monthly precipitation pH value, a polynomial regression model of rapeseed yield was established. By inversion, the model was found to have good effect on yield simulation and disaster assessment.
