摘要:

可视化是促进地理区划知识发现的有效手段,但目前地理区划知识可视化方面的研究较为欠缺,无法满足复杂区划知识的可视化表达及知识发现需求。因此,本文从充分认知区划先验知识出发,建立区划知识的地图表达内容体系,研究面向不同类别区划知识的地图可视化表达方法,进而探讨综合多维区划知识的图谱表达范式,并在此基础上进行了可视化应用案例研究。实验表明,本文提供了有效的区划知识表达和发现策略,可为读者开展进一步的决策和研究提供支持和依据。

Abstract:

Geographical regionalization is a traditional and important content of geographical research. Geographers have carried out research on the dominant factors, characteristics of various geographical regions and the relationship of constraints and dependencies among these geographic elements over the years, accumulating a wealth of procedural knowledge as well as producing a large number of geographical regionalization plans. Some of them are multi-angle, multi-time and serialized. Map visualization is an effective tool and information carrier for expressing the zoning knowledge. However, the current research has always focused on the theory, method and technology of regional division and seldom pay attention to the combination of zoning knowledge and visualization method. In the process of compiling the national zoning atlas (the new century edition), we sorted out academic papers, monographs, reports and atlas related to zoning and found that most of the zoning knowledge existed in the form of text. Visualization is only used to represent the partitioned results. The combination of zoning knowledge and visualization theory and method is very weak, and the visualization expressive content is limited as well as the form of visualization, which is not enough to reflect the profound knowledge connotation and association of geographical zoning. It leads to the lack of zoning knowledge utilization. It hinders the knowledge acquisition in the zoning map. The cartography of new period has changed gradually from the presentation of the data to the expression of knowledge and guide the reader to find out rules which can also show the depth of scientific research to promote the re-use of knowledge. This article starts from making a cognition for prior knowledge of geographical zoning, and establishes the expressive content system of the knowledge of geographical zoning. Then, we study the visualization expressive method for the different knowledge of zoning maps, and discuss visual method of the comprehensive multi-dimensional zoning knowledge based on geo-informatic graphic. Finally, we use a visual case study, which shows that this paper provides an efficient strategy for knowledge representation and discovery, and it can be a further support for research decision-making of various regional factors.

Key words: zoning, visualization, geo-informatic graphic, knowledge representation
