Research History, Hotspot and Future Direction of Danxia Landform on Loess Plateau of Northern Shaanxi Province
-
摘要:
陕北黄土高原丹霞地貌景观带是目前国内已知规模最大的丹霞地貌景观带。基于WOS、CNKI等数据库,笔者全面梳理了1989~2023近35年研究成果,依托CiteSpace 6.3.R1软件,构建了研究文献数量、研究机构、研究作者以及研究关键词等可视化知识图谱,系统揭示了陕北黄土高原丹霞地貌研究历程和热点。研究发现:①陕北黄土高原研究历程呈现由西南边缘地区逐步转向中部地区,由零散研究或个案研究逐步向区域研究转变。②外文文献整体较少,主要以国内文献为主。③对于陕北黄土高原丹霞地貌研究重视程度越来越高,但研究团队、地域之间的合作较少。④研究早期以陕北黄土高原边缘的照金丹霞为主,近期以延安丹霞地貌、靖边龙洲丹霞地貌、甘泉雨岔大峡谷等为主。⑤研究内容主要以“丹霞地貌分类”“景观特征”“沉积环境”“发育机制”等为热点。为进一步推动陕北黄土高原丹霞地貌的科学保护和合理开发利用,未来应注重加强定量研究、深入揭示丹霞地貌形成机理、强化国内国际对比、保护利用协同推进等方面。
Abstract:The Danxia landscape zone of the Loess Plateau in northern Shaanxi is the largest known Danxia landscape zone in China. Based on WOS, CNKI and other databases, this study comprehensively combed the research results of the past 35 years from 1989 to 2023, relying on CiteSpace 6.3.R1 software, constructed a visual knowledge map of the number of research literature, research institutions, research authors and research keywords, and systematically revealed the history of the research on Danxia landforms in the Loess Plateau of northern Shaanxi and its hotspots. The study found that: ① The research history of the Northern Loess Plateau of Shaanxi Province shows a gradual shift from the southwestern fringe region to the central region, and a gradual shift from piecemeal research or case studies to regional research.② There is less foreign literature overall, and the main focus is on the domestic literature. ③ More and more emphasis is being placed on the study of the Danxia geomorphology of the Northern Loess Plateau of Shaanxi Province, but there is less cooperation between the research teams and the geographic regions. ④Early research was dominated by the Zhaojin Danxia on the edge of the Loess Plateau in northern Shaanxi Province, and more recently by the Yan'an Danxia landform, the Longzhou Danxia landform in Jingbian, and the Yucha Grand Canyon in Ganquan. ⑤The research content mainly focuses on "Classification of Danxia landforms", "Landscape characteristics", "Sedimentary environment", "Development mechanism" and so on. "and other hotspots.In order to further promote the scientific protection and rational development and utilization of Danxia landforms in the Loess Plateau of northern Shaanxi, the future directions should focus on strengthening quantitative research, in-depth revelation of the formation mechanism of Danxia landforms, strengthening the domestic and international comparisons, and synergistic promotion of protection and utilization.
