摘要
该文基于文献计量方法,从刊文量、文献共被引及高突现关键词等方面对该领域研究热点及趋势进行可视化分析。结果表明:(1)基于地形地貌结构化特征的等高线综合是永恒的研究主题;(2)数学方法始终为等高线综合研究提供有效的研究方法与手段;(3)已有算法的改进、算法效率及综合结果精度的提高将成为未来研究主要趋势之一;(4)GeoAI、大数据技术为未来等高线综合的研究提供了新契机、新的思路及发展方向。
This paper based on the CiteSpace literature measurement method,the research hotspots and trends of automatic contour generalization are visually analyzed from the aspect of publication volume,co-citation of literature and high prominence keywords.Results indicate that:(1)the structural features of topographic and geomorphic is the eternal theme of generalization;(2)mathematical methods always provide effective research methods for contour generalization;(3)the improvement of existing generalized algorithms,the efficiency of the algorithm and the accuracy of the generalized results will become one of the main research trends in the future;(4)GeoAI and big data technology provide a new opportunity,new thinking and development direction for contour generalization in future.
