Abstract: Taking GIS and ecological environment field as the theme, the 1999—2018 periodical papers in the CNKI database are retrieved 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 development, 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 transformation.

Key words: GIS, ecological environment, visualization, research hotspot, mapping knowledge domain
