空气污染与健康效益评估工具BenMAP CE研发

Research and development of environmental benefits mapping and analysis program: Community edition

为了评估空气污染带来的健康冲击、评估健康效益,克服现有评估工具(BenMAP V4.0)计算速度缓慢及用户体验较差等问题,受美国环保署委托,设计并研发了新一代空气污染与健康效益评估工具BenMAP CE,搭建了BenMAP CE的框架,进行了详细功能设计,并利用美国环保署提供的数据进行了实测.测试结果表明,基于相同的输入文件和设置,BenMAP CE能重现BenMAP V4.0的计算结果,相比现有的评估工具,BenMAP CE具有良好的用户体验、强大的GIS展示功能及大幅提高的计算速度.BenMAP CE是考虑了污染物环境浓度削减、人口密度、收入差异等经济因素的综合性评估工具,能为决策者评估空气污染控制措施所带来的健康效益提供辅助决策依据.

This work describes the framework and development of USEPA′s next generation air pollution and health benefit evaluation tool, Environmental Benefits Mapping and Analysis Program： Community Edition （BenMAP CE）. With the input data of population density, air quality and the associated impact on human activities, BenMAP CE assesses the economic benefits of improved air quality under different emission control scenarios. The CE version significantly enhances the computational efficiency and GIS visualization capability of the current BenMAP release （V4.0）. A case study data provided by USEPA demonstrates that the CE version is capable of reproducing the air quality benefit results of BenMAP V4.0 while offering an improved user experience of the software package. BenMAP CE provides policy makers a comprehensive, user-friendly tool for sound air quality management.
