Abstract: Under the synergistic advancement of the "dual carbon" goals and the rural revitalization strategy, digital and intelligent transformation has become the core path to achieving "high efficiency, low emissions, and high value" in ecological circular agriculture. Taking the aquaponics model as an example, this paper analyzed the opportunities, challenges, and development path of its digital and intelligent-empowered model based on the theoretical framework of "goal-empowerment-industry-mechanism-environment".The aquaponics model achieved precise control of material circulation by constructing a digital and intelligent technology system of "perception-decision-execution", and combined with the extension of the entire industrial chain and policy mechanism support, it formed a low-carbon development model characterized by "technology integration, precise circulation, and diversified value". Practical results indicated that this model increased vegetable yield fivefold compared to traditional planting and fish yield tenfold compared to pond aquaculture. It achieved near-zero application of chemical fertilizers and pesticides along with a water recycling rate approaching 100% which could provide a replicable practical paradigm for the digital and intelligent transformation and low-carbon upgrading of the aquaponics development model.
