了解中国西北干旱区绿洲城市热岛效应研究进展有利于绿洲城市的可持续发展,同时为后期学者的研究方向提供参考.从中国知网学术期刊(网络版)数据库和Web of Science核心库检索并筛选了 1990-2022年发表的相关论文共 67篇,利用Origin 2021软件对年度发文量、机构、主要研究内容进行统计和分析,采用CiteSpace 5.8对作者和关键词进行共现聚类.结果表明:干旱区城市热岛效应的论文数量整体偏少,近年呈缓慢上升趋势,被引频次总体不高;研究尺度以城市尺度为主,研究区多集中在乌鲁木齐市.早期多使用地面气象站观测法,近年来以遥感监测法为主,模型预测法与移动样带测量法在干旱区内应用较少;研究热点是城市热岛效应的影响因素和变化过程,城市热岛效应的缓解策略尚未引起重视.未来应该在多个尺度与多个绿洲城市开展研究,并更加关注城市热岛的缓解策略.
Research progress on heat island effect of oasis cities in arid zone of northwest China
Understanding the research progress of heat island effect of oasis cities in arid areas of northwest China is conducive to the sustainable development of oasis cities,and provides a reference for the future research direction of scholars.A total of 67 relevant papers published from 1990 to 2022 were retrieved and screened from the database of Academic journals(online)of CNKI and the core database of Web of Science.The annual number of papers published,institutions and main research contents were statistically analyzed using Origin 2021 software.CiteSpace 5.8 was used for co-occurrence clustering of authors and keywords.The results showed that the number of papers on urban heat island effect in arid areas was relatively small,and the cited frequency was not high in recent years.The research scale was mainly urban scale,and the research area was mainly concentrated in Urumqi.In recent years,remote sensing monitoring method was the main method,and model prediction method and moving transect measurement method were rarely used in arid areas.The research focus was the influencing factors and changing process of urban heat island effect,but the mitigation strategy of urban heat island effect had not been paid attention to.Future studies should be carried out at multiple scales and in multiple oasis cities,and more attention should be paid to urban heat island mitigation strategies.
