中国城市绿地微气候研究进展——基于CiteSpace的可视化分析

Research Progress on Microclimate in Urban Parks in China:Visual Analysis Based on Cite Space

随着中国城市化进程的快速发展,导致城市热岛效应加剧,威胁居民健康,城市绿地微气候已成为影响城市居民生活环境的关键因素。近年来,风景园林学科对于城市绿地微气候的研究日益重视。本研究运用CiteSpace软件分析过去二十年的相关文献,通过整理关键词发现城市微气候研究主要集中在小气候、数值模拟、热舒适等方面。研究进一步梳理文献来源、研究发展历程、空间分布情况和研究热点等内容,并进行深入评析。并对城市绿地类型与景观要素对微气候的影响、基于数值模拟技术的城市绿地微气候分析与优化、城市绿地公众热舒适度评价这三个方面成果最为丰富的研究内容进行分析。最后结合当前研究的特点与不足提出注重以人为本的城市绿地规划与设计、多感官舒适度评价的耦合、长期的微气候效应评估以及跨区域比较研究的建议。研究旨在探究城市绿地微气候的研究热点和发展趋势,为研究当前城市绿地微气候有关内容提供依据。

With the rapid urbanization in China,urban heat island effect has intensified,posing threats to the health of city residents.The microclimate of urban green spaces has become a key factor affecting the living environment of urban inhabitants.In recent years,the discipline of landscape architecture has increasingly focused on the study of the microclimate in urban green spaces.This study utilizes the CiteSpace software to analyze relevant literature from the past twenty years.By organizing keywords,it was found that research on urban microclimate primarily concentrates on microclimate,numerical simulation,and thermal comfort.The study further collates and critically analyzes the sources of literature,the developmental trajectory of research,spatial distribution,and research hotspots.It also delves into the most substantial research areas:the impact of urban green space types and landscape elements on microclimate,the analysis and optimization of urban green space microclimate based on numerical simulation techniques,and the assessment of public thermal comfort in urban green spaces.Finally,in light of the current research characteristics and gaps,the study proposes recommendations for people-centered urban green space planning and design,the integration of multisensory comfort evaluation,long-term microclimate effect assessment,and comparative research across different regions.The aim of this research is to explore the hotspots and trends in urban green space microclimate studies,providing a basis for current research in this area.
