Visual Analysis of China’ s Land Ecological Security Based on CiteSpace

Based on the relevant research with land ecological security as the keyword in CNKI database from 2001 to 2020, this paper analyzes China’ s land ecological security from the aspects of “research stage” “author” “publishing institution” “keywords” and “research frontier” through CiteSpace software. The results showed that the research of land ecological security in China has experienced the initial exploration stage, rapid development stage and deepening stage. The cooperation among researchers showed the characteristics of overall dispersion and small aggregation, and the research of land ecological security among regions is unbalanced. The most frequent keywords are “land ecological security” , followed by “ecological security” “evaluation” “land ecology” and “PSR model” . At present, the research of the land ecological security is still mainly based on the evaluation of land ecological security. In the future, more models should be introduced to deepen the research on early warning and predicting, human-land coordination and urban ecological improvement.
