Abstract: Eco-environmental degradation has become one of the key factors restricting the health of ecosystems and human well-being around the world. How to mitigate and solve the problem of eco-environmental degradation has become an important content for countries to explore sustainable economic and social development. The European Union (EU) re-alized the seriousness of the eco-environmental problems earlier, and has formed a relatively sound policy system of envi-ronmental integration and established an innovation-driven technology practice system through long-term exploration, which has played an important role in maintaining the sustainable development of the EU. At present, China is at an important juncture of eco-environmental protection. To fully understand the policy and technical practice system of eco-environmental protection and restoration of the EU will be helpful to promote the cause of eco-environmental protection in China. On the basis of relevant literature research and analysis, this paper summarizes the status of eco-environmental protection in the EU, and systematically sorts out the relevant policy systems and technical measures. The paper also proposes that in the fu-ture, eco-environmental protection and restoration should be incorporated into multiple departments, and environmental management mechanisms with public participation should be explored in the field of policy. In terms of innovation of tech-nical measures, it is necessary to promote the localization and mainstream development of nature-based solutions, and build a platform for innovation and exchange of technical measures based on enterprises and multi-participation.
