摘要
以GIS和生态环境领域为主题,检索CNKI数据库中1999—2018年的期刊论文作为数据源,利用科学知识图谱的方法对该领域的研究热点和研究趋势进行可视化分析。研究发现在生态环境与GIS结合领域有少数作者存在合作关系,大部分学者都是进行独立研究,互相之间关联性不强;通过关键词共现分析,发现学者们主要进行生态环境安全、可持续发展、生态敏感性等方面的研究;突变词监测则展示了GIS在生态环境领域近20年的研究热点转换,经历了从以地理信息技术为主、生态环境为辅到关注水土流失等可持续发展,再到以生态系统评价为重心的转变过程。
Taking GIS and ecological environment field as the theme,the 1999—2018 periodical papers in the CNKI database are re⁃trieved as the data source,and the method of mapping knowledge domain is used to visually analyze the research hotspots and research trends in this field.The study found that in the field of the combination of ecological environment and GIS,there are a few scholars who have a cooperative relationship.Most scholars conduct independent research and are not closely related to each other.Through keyword co-occurrence analysis,the study found that scholars mainly conduct research on ecological environment security,sustainable devel⁃opment,and ecological sensitivity.The monitoring of mutant words demonstrates the transformation of research hotspots of GIS in the field of ecological environment in the past 20 years.It has experienced sustainable development ranging from geographic information technology as a supplement to ecological environment to the focus on soil erosion,to the focus on ecosystem evaluation process of trans⁃formation.
