The invention provides a method for constructing an industrial park 
atmosphere pollution characteristic online 
monitoring system, particularly a method for constructing an online 
monitoring system for industrial park emission including 
atmosphere characteristic 
pollution factors, such as VOCs, inorganic gas and 
odor substances, and relates to the technical field of industrial park 
atmosphere environment online monitoring. The method for constructing the industrial park atmosphere 
pollution characteristic online 
monitoring system comprises the steps: A, selecting a 
monitoring site; B, determining a monitoring factor; C, screening a 
pollutant monitoring instrument; D, establishing an atmosphere automatic monitoring 
system; and E, constructing an 
information management system. According to the method for constructing the industrial park atmosphere pollution characteristic online monitoring 
system, a mutually complementary atmosphere pollution early-warning and monitoring system is obtained by screening automatic monitoring instruments, which are used for optimally controlling pollutants and are integrated with a 
chromatography, a sensor, a 
mass spectrometry, an optical technology and so on, on the basis of atmosphere characteristic pollution analysis from three levels of the park, the boundary and sensitive points; online real-
time control of industrial park atmosphere characteristic pollution unorganized emission, industrial park boundary and factory boundaries is realized, so that the atmosphere pollution is converted from manual prevention to technical prevention; and therefore, a novel 
environment management mode is established.
