In this sense, the "Happiness Plan" is not only a development initiative of a region, but also represents a rural revitalization paradigm led by ecological civilization. It tells us that as long as we firmly practice the concept of "green water and green mountains are gold and silver mountains" and give full play to resource endowments and technological advantages according to local conditions, we can fully explore a rural revitalization path that suits our own reality, so that green waters will always be green, villages will always be prosperous, and people will always be rich. It can be foreseen that with the continuous support of policies and the continuous promotion of experience, the Pan'an-style ecological co-enrichment model will bear fruit in more places and make greater contributions to my country's rural revitalization cause. The ecological-biological-economic integrated development model explored by Pan'an has not only achieved the current revitalization goals, but also demonstrated strong sustainable development potential. First of all, from the perspective of environmental sustainability, this model is based on ecological carrying capacity, follows the laws of nature, and avoids over-exploitation of resources and environmental overdraft. For example, the reduction of agricultural inputs and the recycling of waste ensure that soil fertility and biodiversity can be maintained for a long time, and the ecosystem service function has increased rather than decreased, leaving green assets for future generations. This has laid a sustainable ecological foundation for rural revitalization. Secondly, from the perspective of economic sustainability, through the industrial upgrading driven by biotechnology, the endogenous growth momentum of the rural economy has been enhanced. The extension of the industrial chain and the increase in value have increased the resilience of rural areas to macroeconomic fluctuations; the diversified industrial layout has reduced the risk of a single industry; and the circular economy has reduced dependence on external inputs. All these have made the rural economic system more resilient and dynamic, and can continue to create jobs and income. Moreover, rural industries are gradually integrated with urban markets and international markets, and the supply capacity of high-quality green agricultural products and ecological services has been continuously enhanced, with a promising long-term development prospect. Thirdly, from the perspective of social sustainability, this model has promoted rural social governance and cultural revitalization. Farmers' income has increased, the number of young people returning to their hometowns to start businesses has increased, and the rural population structure has improved; joint participation in ecological industries has strengthened the village collective economy and enhanced the cohesion of grassroots organizations; ecological civilization education has been deeply rooted in the hearts of the people and promoted the green transformation of lifestyles. These positive changes at the social level have provided a guarantee for the long-term stability and prosperity of rural areas. It can be said that the ecological-biological-economic integrated development model not only focuses on the present, but also looks to the long term, and meets the basic requirements of sustainable development. Of course, to fully unleash the potential of this model, it is necessary to continue to exert efforts in policies, technology, and investment. First, in terms of policy, a sound mechanism for realizing the value of ecological products should be established to provide institutional guarantees for the transformation of green waters and green mountains into gold and silver mountains. Improve ecological compensation, green finance, etc., so that the subjects engaged in ecological agriculture can get due returns. Second, in terms of science and technology, we must continue to strengthen the research and development of applicable technologies, such as carbon sink agricultural technology and biodiversity-friendly production technology, to cope with new challenges such as climate change and maintain the advancement and competitiveness of the model. Third, in terms of investment, we need to increase the construction of rural green infrastructure and public services, especially in the fields of digital new infrastructure and human settlement environment improvement, to lay a solid foundation for sustainable development. In short, the ecological-biological integrated revitalization model represented by the Pan'an experience is an important path for China's rural revitalization. It proves that protecting the ecological environment and developing the economy are not contradictory, but can complement and enhance each other. In the future, we have reason to believe that with the continuous improvement and promotion of this model, more green revitalization paths with their own characteristics will emerge in China's vast rural areas, contributing the "Chinese example" to global sustainable development.
