摘要
为探索近年来我国建筑节能研究的进程、热点和趋势,采用CiteSpace对CNKI数据库上2000年至2020年该研究领域内的1 437篇有效文献进行了科学知识图谱分析.研究结果表明,20年来该领域的发展进程大致可划分为三阶段:初级发展(2000-2007年)、快速增长(2008-2015年)、细化延伸(2016-2020年),并分别呈现为研究主题较为单一、在广度和深度上较快发展、研究内容更加精细化.研究发现"BIM技术"、"敏感性分析"、"多目标优化"、"建筑全生命周期"、"可再生能源技术"、"节能改造"等为领域研究热点.整体研究体系呈现为支撑层、场景层和目标层三大层次.在该领域的研究对象、方法、目标上,向着精细化研究、全局敏感度研究、多目标优化研究、基于BIM的"通用集成"、"全生命周期贯通"等方向发展.以期为建筑节能领域的发展与实践提供借鉴.
Abstract
To explore the research process,hotspot and trend in building energy efficiency research in China in recent years,CiteSpace was used to analyze 1,437 valid literatures in the CNKI database from 2000 to 2020.The results show that the development process of this field in the past 20 years can be roughly divided into three stages:primary development(2000-2007),rapid growth(2008-2015),and detailed extension(2016-2020).The three stages respectively show the phase with relatively simple research topic,rapid development in breadth and depth,and more refined research content.It is found that"BIM","sensitivity analysis","multi-objective optimization","whole life cycle of building","renewable energy",and"energy saving renovation"are the research hotspots in the field.The overall research system presents three levels of support layer,scene layer,and target layer.In terms of research objects,methods,and objectives,it develops towards the direction of fine research,global sensitivity research,multi-objective optimization research,BIM-based"general integration",and"full life cycle penetration".
