Abstract: The National Conference on Ecological Environmental Protection in 2023 and 2024 emphasized the need to strive to improve the diversity, stability and sustainability of ecosystems through ecological protection and restoration. However, there are few scientific studies that consider all three in an integrated manner. Therefore, this paper innovatively takes diversity, stability and continuity coupling as the perspective, combs through the differentiated application of ecological restoration measures, explores the correlation between ecological restoration and ecosystem diversity, stability and continuity, finds that ecological restoration affects ecosystem diversity, stability and continuity through the influence on ecosystem structure, process, and function, and then analyzes ecosystem diversity, stability and continuity based on the existing research finally. Finally, based on the existing research, we analyze the indicators and evaluation methods of ecological restoration effectiveness assessment of three-dimensional characteristics, which will provide a scientific basis for the in-depth promotion of ecological protection and restoration and the construction of beautiful China. In the future, we can continue to study and fill the gaps in the scientific meaning and ecological restoration effect evaluation of ecosystem diversity stability sustainability, deepen the study of the interaction relationship within the three-dimensional characteristics of ecosystems, explore the impact mechanism of ecological restoration on ecosystem characteristics, strengthen the research on the ecological restoration effect evaluation system based on ecosystem status, in order to provide a new perspective and technical support for the effectiveness evaluation of ecological restoration.
