[目的]研究重庆万州区SO2污染状况，为农业的可持续发展提供支持。[方法]该研究通过总结万州区SO2浓度的年内逐日变化规律，探讨SO2浓度与降水量、大气压强、风速、气温、相对湿度、日照时数6个气象因子之间的关系，并用因子分析法分析主要的影响因素。[结果]重庆万州区SO2污染主要集中在冬季，SO2浓度与6个气象因子之间有4个存在显著性的相关关系，其中与降水量、风速、气温呈显著负相关，而与气压呈现显著正相关。因子分析法得到万州气象因子变化主要受到辐射能量、水汽和风速3个主要成分的影响，并建立了SO2浓度的预测模型。[结论]该研究的预测模型可以为万州区农业生产中预防SO2和酸雨污染提供依据。

[Objective] The aim was to study the pollution of SO2 in Wanzhou, to provide supportfor the sustainable de-velopment of agriculture. [Method] Through sum marizing the daily variation of the SO2 concentration in W anzhou District,the relationship between the SO2 concentration and the six meteorological factors were explored, including precipi-tation,atm ospheric pressure,wind speed, air temperature, relative hum idity and sunshine hours. And the main factors was analyzed by the factor analysis method. [Result]The pollution of SO2 in Wanzhou was mainly concentrated in the winter. There were four factors that had significant correlation relationship be-tween the concentration of SO2 and six meteorological factors.The precipitation, wind speed, air temperature had signifi-cantly negative correlation and the atmo-spheric pressure showed a significant positive correlation.The change of mete-orologicalfactors in Wanzhou was main-ly influenced by three main com ponents that were radiantenergy,water vapor and wind speed through the factor analysis method.And the prediction model of SO2 concentration in Wanzhou was built [Conclusion]The predi ctionmodel of SO2 concentration in Wanzhou could help agriculture prevent SO2 and acid rain pol-lution.
