运用CiteSpace对Web of Science和中国知网相关文献进行梳理，分析该领域的研究热点与进展。结果表明:国内外发文量都在不断增加。2013年后，发文量增长迅速，国外增速明显快于国内;国外文献作者和机构形成了以美国各大高校为中心的较强合作网络关系，核心研究作者发文量达 39%。国内文献作者和机构联系较弱，呈多中心分散式结构，核心研究作者发文量仅占 8%;关键词可视化表明国内外研究同步性较强，均以环境暴露的健康影响和疾病负担研究为基础，国外侧重具体影响机制与联系及风险评估研究，国内更关注影响因素及政策效益剖析;国外研究从环境暴露对健康终点影响发展到协同适应策略及复杂模型构建，目前全球负担和颗粒物质减排是研究热点。国内研究从气候变化和大气污染对健康的影响评估发展到协同治理对策及健康风险，当前减缓气候变化及减污降碳的健康协同效益研究是热点。将来针对气候变化和大气污染导致的健康问题及敏感区域、公共健康效应时空规律的识别和明晰是重点，健康风险评估模型构建与早期预警系统的开发应用也迫在眉睫。
Research hotspots and trends of the health effects of synergistic emission reduction of greenhouse gases and air pollutants
CiteSpace was used to sort out the relevant literature on Web of Science and China National Knowledge Infrastructure,and analyze the research hot spots and progress in this field.The findings revealed that,first the number of published works had been steadily increasing both domestically and internationally.Particularly,after 2013,the number of published articles has been growing rapidly,with a significantly higher rate observed in international publications compared with domestic ones.Second,a robust collaborative network was established by foreign literature authors and institutions,primarily centered around major universities in the United States.The number of core research authors who had published articles in this network has reached 39%.Conversely,it appeared that the relationship between domestic authors and institutions was weaker,exhibiting a decentralized structure with multiple centers.The publications of core research authors accounted for only 8%of all domestic literature works.Third,The strong synchronicity between domestic and foreign research was indicated by the results of the visual analysis,focusing mainly on studying the health effects and burden of disease caused by environmental exposure.However,specific impact mechanisms,linkages,and risk assessment were more emphasized by foreign researches.On the other hand,influencing factors and policy benefits were paid closer attention to by domestic researches.Fourth,ranging from studying the impact of environmental exposure on health endpoints to investigating climate change co-adaptation strategies and developing complex models,foreign researches centered more on global burden and decrease of particulate matter emissions.On the other hand,Domestic researches had evolved from studying the effects of climate change and air pollution on health to exploring coordinated governance countermeasures and health risks.Currently,there was considerable interest in the potential synergistic benefits of climate change,pollution reduction,and carbon reduction on health.In the future,the identification and clarification of the spatiotemporal patterns of health issues and sensitive areas,as well as public health effects caused by climate change and air pollution will be a key focus.The construction of health risk assessment models and the development and application of early warning systems should also be put on top agenda.
