Aiming at the impact of motor vehicle/ship/engineering machinery emissions on the atmospheric quality of typical regions in China, establish a corresponding analysis model and prediction method. Analyze the environmental impact factors of mobile sources in air pollution, including vehicles /ships/construction machinery and the causes of atmospheric pollution. According to the comprehensive data of vehicles/ships/construction machinery usage, policies and regulations, restrictions on motor vehicles, wind speed and direction in the target area, the countermeasures against air pollution are proposed. Atmospheric sample data analysis and other related services. Provide the atmospheric sample collection. Provide vehicle exhaust gas sample collection and data analysis and other technologies.
