中国PM2.5暴露人群健康损失评价及区域差异分析

评价了中国31个省(区、市)PM2.5污染造成的人群健康损失经济价值,研究了第二产业发展、煤炭消费和公路货运等社会经济因素对其的综合影响。结果显示,由于PM2.5污染较重,人口数量较大,京津冀及周边地区(包括北京、天津、河北、山西、山东、河南)、长三角地区(包括上海、江苏、浙江)、长江中游地区(包括安徽、江西、湖北、湖南)PM2.5暴露人群健康损失经济价值较高,分别为28787.38亿、15032.57亿、13763.20亿元,分别占全国总量的33.48%、17.48%、16.01%,其他地区PM2.5暴露人群健康损失经济价值较低。第二产业发展、煤炭消费和公路货运对暴露人群健康损失经济价值/国内生产总值越高的地区驱动影响越大。

Assessment and regional diversity analysis of public health loss attributed by PM2.5 exposure in China

The economic value of public health loss attributed by PM2.5 exposure for 31 provinces of China was assessed. Comprehensive impact of secondary industry development,coal consumption and road freight transportation was studied. Results showed that due to the severe PM2.5 pollution and huge population,economic value of public health loss attributed by PM2.5 exposure was high in Beijing- Tianjin-Hebei and surrounding areas (including Beijing,Tianjin,Hebei,Shanxi,Shandong and Henan),Yangtze River Delta area (including Shanghai,Jiangsu and Zhejiang) and middle reaches of the Yangtze River (including Anhui,Jiangxi,Hubei and Hunan),which reached2 878.738 billion,1 503.257 billion and1 376.320 billion yuan,accounting for 33.48%,17.48% and16.01% of the national gross,and that in other areas was low. The comprehensive impact of secondary industry development,coal consumption,and road freight transportation on the economic value of public health loss attributed by PM2.5 exposure strengthened with economic value of public health loss/gross domestic product.
