The Relationship between Ozone Generation and Precursors,and Their Sensitivity and Control Analysis in Leshan City

In order to understand the main characteristics and scientific control of ozone generation in Leshan City,Pearson correlation analysis was used to analyze the correlation between ozone and its precursors in the past year,and OBM model and VOC_S/NO_X ratio method were used to discuss the sensitivity and control characteristics of ozone generation.The results showed that there was a positive correlation between nitrogen oxides and ozone in summer and autumn,and a negative correlation between nitrogen oxides and ozone in spring and winter.Ozone generation potential P_{O_(3}-NO) was obtained from the sensitivity analysis of ozone:Summer>Autumn>Spring>Winter;In addition,the controlling analysis of ozone generation shows that the ozone generation in Leshan mainly belongs to the nitrogen oxide control area.Spring and autumn mainly belong to the VOC_S control area,summer and winter mainly belong to the nitrogen oxide control area.Therefore,ozone prevention and control in Leshan City should be divided into seasonal prevention and control:the main control of nitrogen oxide emissions in summer,spring and autumn two seasons mainly control VOC_S emissions.
