基于BenMAP的珠三角PM_(10)污染健康经济影响评估

以珠三角地区广州麓湖公园等13个典型监测站的监测资料为基础,结合地图资料、人口资料、疾病发病率、健康影响函数、价值衡量函数等,运用BenMAP模型评估了《珠江三角洲地区空气质量管理计划(2002—2010年)》实施后PM10污染的变化对公众健康的改善情况(选取2006年和2010年为基准年进行对比研究)。结果表明,该地区2006年到2010年通过减少PM10改善空气质量可以挽救346条生命,使1 092人免患慢性支气管炎;其经济影响占GDP的比重由2006年的0.66%降低到2010年的0.45%,说明了该地区减排措施的健康有益性。

Based on data from 13 typical monitoring stations such as Guangzhou Luhu Park in the Pearl River Delta region, combining the GIS shape files, population data, incidence data, health impact function and valuation function, this article uses BenMAP model to assess the health benefits from the reduction of PMt0 pollution after the implementation of the＂Pearl River Delta regional air quality management plan（2002-2010）＂（select 2006 and 2010 as base year respectively ）.The results show that：the improvements of air quality in PRD by reducing the emissions of PM10 from 2006 to 2010 could save 346 lives and 1 092 people from chronic bronchitis. The ratio of economic impact to GDP decreases from 0.66% in 2006 to 0.45% in 2010. All of these illustrated the health benefits of emission reduction measures in PRD.
