A knowledge graph analysis was conducted on 4 160 journal articles retrieved under the topic of high-quality development of urban-rural greening guided by the transformation of ecological function from 2005 to 2025 to elucidate the high-quality development of urban-rural greening and the implementation path within the context of Ecological Civilization Initiative in China. The connection and integration relationship between the functional mechanisms-transmission pathways-welfare benefits during the high-quality development of urban-rural greening was systematically combed. The results showed that the essence of high-quality development path of urban-rural greening under the guidance of the transformation of ecological function is a process of the complete transformation of multi-level human welfare covering the individual health，community vitality，and sustainable development of urban through a series of complex biophysical processes mediated by specific effects of environment. A multi-functional synergy model for the high-quality development of urban-rural greening was proposed based on the externalization and transformation of ecological function to focus on deepening the mechanism for transforming welfare benefits，promoting the deep realization of human welfare from basic guarantees to perceptual gains. A multi-dimensional implementation path of “planning guidance-process monitoring-systematic evaluation-dynamic management” was established to strengthen the resilience of ecosystem services in urban-rural greening. The transformation of urban- rural greening from green quantity to green quality，integrated green，and people-oriented will be promoted on the basis of the synergistic enhancement and dynamic feedback of ecological functions to continuously advance the implementation of the major strategies of constructing ecological civilization and developing with high-quality.
