This study uses the knowledge graph tool CiteSpace to identify and analyze the literature related to ecological compensation research published in academic journals in the CNKI database, in order to provide an objective and scientific reference for the research in this field. The results show that the domestic research on ecological compensation began to appear around 2000, and the first research boom was ushered in starting in 2009. Most studies have explored ecological compensation from the connotation of ecological compensation, compensation subjects and objects, compensation standards, compensation methods, compensation supervision and evaluation of compensation effects, etc., and the articles on ecological compensation standards are relatively more abundant. At the same time, ecological compensation research is often linked to the realization of ecosystem service value and ecological product value. In the future, researchers should focus on establishing and improving the ecological compensation standard accounting system, exploring the market-based ecological compensation mechanism, attaching importance to the ecological compensation fund distribution mechanism, and strengthening research related to ecological compensation effect assessment. Ecological compensation theory should be developed in the direction of deepening and providing new research perspectives for helping China to deal with the relationship between conservation and development.展开更多
