以交通污染严重的北京市建成区为研究区,在前人实地观测的基础上,利用泊松回归相对风险度模型与环境健康价值评估方法,定量评估了北京市道路绿地消减 PM2.5总量及其健康效益.结果表明:北京市建成区道路绿地年消减 PM2.5总量为 1.09t;对降低人群健康风险作用较为显著,可减少受危害总数约3024例,其中早逝18例、呼吸系统疾病住院53例、心血管疾病住院25例、儿科门诊324例、内科门诊761例、急性支气管炎1134例、慢性支气管炎264例、哮喘445例;带来的健康经济效益为1.98亿元.建议加强道路绿地建设,丰富植被层次结构,以积极应对城市交通空气污染.

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.
