Abstract: Bibliometric methods and knowledge graph were used to clearly understand the current status of ecological restoration evaluation in China. The 1 523 papers collected in CNKI database in past 30 years were used as the data source to analyze the relevant literature of ecological restoration evaluation. The results show that:(1)The discipline communication intensity of ecological restoration evaluation research is low, the overall volume of authors' publications is not high, and the authors' cooperative groups are small. Among the research institutions, Beijing Forestry University, Lanzhou University and Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences are the highest contributors; (2)The research hotspots of ecological restoration evaluation mainly focus on three parts:ecological restoration evaluation types, evaluation indexes of different functional types and restoration effectiveness; (3)The research hotspots of ecological restoration evaluation have gone through three stages, and all stages presented their distinct characteristics of the time. The research hotspots of each stage are deepened compared with the previous stage. In the early stage, some specific ecosystem restoration is evaluated mainly combined with the actual needs. In the later stage, with the progress of various ecological restoration work, different ecological restoration evaluation systems appeared. In recent years, the focus of research has shifted to policy-oriented and technology integration as the support of evaluation. The research results can provide reference for the further strengthening of ecological restoration evaluation research.
