智利的圣地亚哥是拉丁美洲空气污染最严重的城市之一。作为减少大气污染计划的一部分，圣地亚哥地区市政府确定了一项环境政策目标，即利用城市森林去除大圣地亚哥地区小于10 μ m的颗粒物（PM10）。我们使用成本效益，或建立成本和选择成本最低的替代方案的过程来获得已定义的PM10去除政策目标，以分析该政策目标。在这项研究中，我们基于社会经济阶层，通过干沉积城市森林效应模型，利用现场和实时污染和气候数据，量化了圣地亚哥城市森林对PM10的去除。利用管理费用调查和智利规划与合作部的文件估计了城市森林管理费用。结果表明，根据世界银行制定的标准，管理城市城市森林（树木、灌木和草地由圣地亚哥的36个城市管辖）以消除PM10是一项具有成本效益的减少PM10的政策。此外，我们比较了管理城市城市森林和行道树与其他控制政策（如替代燃料）的成本效益，以减少圣地亚哥的PM10，并确定城市城市森林管理效率与其他空气质量改善措施相似。(C) 2007 Elsevier Ltd.版权所有。
Santiago, Chile has the distinction of having among the worst urban air pollution problems in Latin America. As part of an atmospheric pollution reduction plan, the Santiago Regional Metropolitan government defined an environmental policy goal of using urban forests to remove particulate matter less than 10 mu m (PM10) in the Gran Santiago area. We used cost effectiveness, or the process of establishing costs and selecting least cost alternatives for obtaining a defined policy goal of PM10 removal, to analyze this policy goal. For this study, we quantified PM10 removal by Santiago's urban forests based on socioeconomic strata and using field and real-time pollution and climate data via a dry deposition urban forest effects model. Municipal urban forest management costs were estimated using management cost surveys and Chilean Ministry of Planning and Cooperation documents. Results indicate that managing municipal urban forests(trees, shrubs, and grass whose management is under the jurisdiction of Santiago's 36 municipalities) to remove PM10 was a cost-effective policy for abating PM10 based on criteria set by the World Bank. In addition, we compared the cost effectiveness of managing municipal urban forests and street trees to other control policies (e.g. alternative fuels) to abate PM10 in Santiago and determined that municipal urban forest management efficiency was similar to these other air quality improvement measures.
