摘要
为探究学科领域科研产出的主题与空间分布规律,发掘科研产出主题社群分布与空间聚集的影响因素,基于中国知网下自然地理学与测绘学分类核心期刊,选择2000—2019年的题录数据,分别提取关键词与机构信息,对其主题与空间分布情况进行可视化展示,探索其分布规律。结果显示:学科内形成了4个彼此区别但内部联系密切的研究社群,主题间的融合与分化并存;空间分布呈现明显的不平衡现象,存在显著的空间聚集与自相关性。
To explore the themes and spatial distribution rules of scientific research output,as well as theme community distribution and the influence factors of spatial aggregation,this article respectively extracts the keywords and institutional information from the China National Knowledge Infrastructure“natural geography and geomatics”classification of core journals from 2000 to 2019 and visualizes their themes and spatial distribution with the aim of exploring distribution laws.Results show that there are four distinct but closely related research communities in the discipline,where the integration and differentiation of themes coexist.The spatial distribution is obviously unbalanced with obvious spatial aggregation and autocorrelation.
