The invention relates to the field of PM2.5 prediction in environmental monitoring, and particularly discloses a PM2.5 pollution monitoring and predicting method, which comprises the following steps of: firstly, dividing a past period of time into time nodes according to a set time interval, secondly, acquiring the concentration values of a plurality of air pollutants and the concentration value of PM2.5 measured by a monitoring station in each time point in the past period of time, and acquiring the concentration values of the plurality of air pollutants measured by the monitoring station atthe current moment, thirdly, predicting the concentration of PM2.5 at the current moment by using a linear regression model, predicting the PM2.5 concentration of a specific place according to the detection values of the air pollutants at different places in a certain area, and finally, comparing the predicted PM2.5 concentration with a set PM2.5 threshold value, and when the predicted PM2.5 concentration is larger than t
