当今城市面临着气候变化加剧的影响,城市气候脆弱性评估成为应对气候变化科学领域关注的热点和重要的分析评估工具.本文以Web of Science数据库中2002-2022年的英文文献为研究对象,运用可视化软件"引文空间"绘制知识图谱,通过分析城市气候脆弱性评估的发文情况、学科结构、区域合作、知识基础、研究前沿和研究热点等发现:(1)研究发展可分为三个阶段;(2)区域合作主要集中于科研研究趋势良好的国家,如德国、英国、美国和荷兰;(3)学科结构主要涉及城市环境、地质与生态、社会科学;(4)知识基础主要为面对气候变化影响的风险评估和风险评估的响应措施两大类内容,以综合评估城市气候脆弱性和提升城市气候适应能力为研究前沿;(5)"城市可持续发展战略""高热影响下的人居环境"和"海平面上升带来的影响"是如今的研究热点,未来研究重点可能集中于生态系统、可持续性和降雨情况.本文解析城市气候脆弱性评估相关理论视角与方法,以期为进一步深化我国气候脆弱性的治理体系与内容提供参考.
Bibliometrics and Knowledge Mapping Analysis of Urban Climate Vulnerability Assessment in English Literature Based on CiteSpace
Nowadays,cities are facing the intensified impact of climate change.The research on urban climate vulnerability has become a hot topic and an important analytical and evaluation tool in the field of climate change science.In this paper,English literatures from 2002 to 2022 in the database of"Web of Science"are taken as the research object.Visualization software CiteSpace is used to draw the knowledge map.By analyzing publications,disciplinary structure,regional cooperation,knowledge base,research frontiers and research hotspots in urban climate vulnerability assessment,the following findings are found.(1)Research and development can be divided into three stages.(2)Regional cooperation mainly focuses on countries with good research trends,such as Germany,the United Kingdom,the United States,and the Netherlands.(3)The discipline structure mainly involves urban environment,geology and ecology,sociology.(4)The knowledge base mainly consists of risk assessment and response measures under the impact of climate change.Comprehensive assessment of urban climate vulnerability and improvement of urban climate adaptation capacity are the research frontiers.(5)"Urban sustainable development strategy","human settlements under the influence of high heat"and"the impact of sea level rise"are currently hot research areas,and future research may focus on ecosystem,sustainability and rainfall.This paper analyses the theoretical perspectives and methods related to urban climate vulnerability assessment,with a view to providing reference for further deepening the governance system and content of climate vulnerability in China.
