定性GIS研究热点挖掘与分析

为了研究定性GIS的研究进展,该文借助文献计量学方法对在Web of Science库中1994年到2013年间的文献进行了挖掘分析。通过文献分析软件Histcite和Citespace对定性GIS文献的挖掘与分析,发现定性GIS的研究热点主要集中在空间推理及其方法和算法的探讨、空间信息的定性表示等方面。定性GIS在1999年有了突破性的进展,但定性GIS并没有只单纯应用于地理学范畴,而是在随后的发展中,较多地应用在社会科学和自然科学等领域。

The hot issues mining in the field of qualitative GIS research

With the development of technology in the past few decades,the field of qualitative GIS research which has broken the ‘bottle neck’ that it only can interpret phenomenon by figures has received wide attention.So a flood of literature appeared.In order to explore the trend and the research hot-spot of qualitative GIS,there are 2 540 papers searched "qualitative GIS,qualitative spatial reasoning,qualitative geography,etc." as key words from 1994 to 2013 in "Web of science" database.Our paper set up the citation relationship network of database by the software Histcite.And the historical citation relationships,the hot-spot papers,key words and journals are visualized on the platform of Citespace.The image shows the hot-spot mainly concentrates on researching the methods of spatial reasoning,and the qualitative representation of spatial information.In 1999,the development of qualitative GIS came to a key point in its development history,and appeared a lot of hot-spot key words and journals.In the meantime,qualitative GIS also has been more and more widely applied in every filed,such as culture,health,economy,urban construction,politics,etc.
