摘要: 为了评价石家庄城市园林绿地吸附空气中悬浮颗粒物,进而减少其对人体健康危害的影响,采用大气污染物干沉降通量模型和暴露—反应关系模型定量评估了2013年石家庄市园林植物吸附PM10与PM2.5总量及产生的健康效益。结果表明:石家庄市园林绿地吸附PM10的总量为13813.4 t/a,吸附PM2.5的总量为6974.6 t/a,导致减少死亡11.58人/d,呼吸系统入院32.12人/d,折合经济价值每年约为19.5亿元,占国民生产总值的4.3‰。该结果为园林绿化植物降低大气颗粒物污染、优化人类生存环境及城市园林绿化规划提供了理论依据。

Abstract: In order to evaluate the dust absorption ability of urban garden green space on the suspended particulate matters in the air, and reduce the harm of these particulate matters to human health, atmospheric pollutants dry settling flux model and exposure-response relation model were used for quantitative assessment of the total amount of PM10 and PM2.5 absorbed by garden plants in Shijiazhuang City and the health benefits of garden green space in 2013. The results of the survey showed that: in Shijiazhuang City, garden plants’ adsorption amount of PM10 was 13813.4 t/a and PM2.5 was 6974.6 t/a in 2013, which reduced the mortality by 11.58 person/day and the respiratory system disease morbidity by 32.12 person/day, and could be converted to 1.95 billion yuan in economic value and was 4.3‰ of the gross national product (GNP). The results could provide a theoretical basis for the research on absorption ability of landscape plants on atmospheric particulate matter, optimizing the human living environment and urban landscape planning.
