The invention discloses a duckweed carbon sink evaluation method, system and equipment suitable for a rice-duckweed symbiotic system, and relates to the technical field of agricultural production and ecological environment, the method comprises the following steps: after rice is harvested, collecting duckweed information in the rice-duckweed symbiotic system by using spectrum scanning and laser point cloud technologies, and determining the duckweed volume based on the duckweed information; determining duckweed biomass in the rice-duckweed symbiotic system according to the duckweed volume; and estimating the duckweed carbon sink by adopting an artificial neural network algorithm and the duckweed biomass, or estimating the duckweed carbon sink by adopting a duckweed carbon sink estimation formula and the duckweed biomass. According to the method, flexible evaluation of duckweed carbon sink can be realized according to information such as rice agronomic management, soil and climate, and good technical support is
