Based on the hourly monitoring results of surface wind speed, wind direction and fine particles (PM_2.5) in 13 cities of Jiangsu Province in 2019—2021, the influence of the frequency of wind speed range and the percentage of PM_2.5 contribution were figured out. The results show that the influence on research area fixed station is different between the frequency of wind speed range and the percentage of PM_2.5 contribution. In general, within the radius of 7 km, the influence probability of wind speed is 78.9% and the contribution of PM_2.5 is 82.4%. Within a radius of 3 km, the frequency of nearsurface wind speed is 70.4%, and the contribution of PM_2.5 is 80.6%. From the perspective of regional variation, the frequency of 0～3 m/s wind speed range is 59.4%~92.0%, with an average value of 78.9%. In Nanjing and Lianyungang, the proportion of PM_2.5 contribution and the frequency of wind speed are inversely proportional to the site radius.
