Abstract：Taking Beijing urban area with serious traffic pollution as a case study and based on prior field observation, we estimate the total amount of PM2.5 removed annually by road green space and its health benefits by using the poisson regression model and environmental health evaluation method. The results showed that the road green space in Beijing urban area remove 1.09 tons PM2.5 annually, which reduced the population health risk significantly, he road green space reduced the total number of 3024 cases of harmful diseases, including 18 cases of premature deaths, 53 and 25 cases of hospital admissions for respiratory and cardiovascular diseases, 324 and 761 cases of pediatric and internal outpatients respectively, 1134 and 264 cases of acute bronchitis and chronic bronchitis, 445 cases of asthma respectively. Consequently, it obtains economic benefit of 198 million Yuan for health-related economic benefits. Thus, we suggest strengthening the construction of road green space and enriching vegetation hierarchy to cope with urban traffic air pollution actively.
