基于文献计量学的环境健康效益评估研究热点及趋势分析

Research Focus and Trend Analysis of Health Benefit Evaluation Based on Bibliometrics

健康效益评估的主要目的是向管理者和公众提供某一项环境保护行动或政策全面的社会效益和成本信息,包括人类健康、环境污染缓解程度、生态资源的改善以及对经济的影响.本文基于文献计量学,结合Citespace软件对中国知网(CNKI)和Web of Science核心数据库中1990—2022年发表的与健康效益评估相关的文献进行可视化分析,以了解该领域的研究热点和趋势.结果表明:①近30年来健康效益评估领域的发文量呈增长趋势,尤其是2015年之后,发文量增长迅速,发文量最多的是美国和中国.②研究成果发表在Science、Lancet、Environmental Science&Technology、Environmental Health Perspectives等顶级期刊上,美国环境保护局和中国科学院是发文量最多的研究机构.③研究热点主要包括大气污染物的减排效果及收益,颗粒物暴露的健康风险和疾病负担研究,以及城市绿地规划等.研究显示,健康效益评估领域在国内外的研究方向和脉络类似,正处于活跃发展状态,主要集中在环境污染的缓解效果、大气污染与人体健康、政策的成本效益分析等领域,减排政策实施后不同污染物的协同效益、温室气体减排行动的效果、新污染物的健康风险评估和控制成本是未来的研究趋势.

The main objective of health benefits assessment is to provide regulators and the public with comprehensive and up-to-date information on the social benefits and costs of an environmental protection actions and policies.This includes assessing the impact on human health,extent of environmental pollution mitigation,improvement of ecological resources,and economic implications.To gain insights into the current research trends and hotspots in health benefit assessment,a review of the literature published from 1990 to 2022 was conducted using bibliometrics and Citespace software.The analysis covered publications from CNKI and Web of Science core datasets.The results indicate several key findings.First,the number of publications in the field of health benefit evaluation has increased steadily over the past 30 years.The growth has been significant since 2015,with the United States and China having the highest number of publications.Moreover,the United States leads in research activity in this field.Secondly,research findings related to health benefit assessment are published in top-tier journals such as Science,Lancet,Environmental Science&Technology,and Environmental Health Perspectives.The most prolific research organizations in this field are the US Environmental Protection Agency and the Chinese Academy of Sciences.Additionally,there are a lot of collaborative exchanges between countries.Lastly,the research focuses on the effects and benefits of reducing air pollutant emissions,as well as the health risks and disease burden of exposure to particulate matter.Urban green space planning is also a prominent research area.The findings highlight similarities in the research directions and context of health benefit assessment domestically and internationally.The filed is in an active development state,with a strong emphasis on the mitigation effect of environmental pollution,air pollution and human health,and cost-benefit analysis of policies.The future research trends identified include investigating the synergistic benefits of reducing environmental pollution through policy implementation,exploring the effect of greenhouse gas emission reduction actions,and assessing the health risk assessment and control cost associated with emerging pollutants.
