Ecological environment protection data are comprehensively collected, the environment situation is dynamically researched and judged through a mathematical algorithm, the environment quality is predicted, the environment problem is intelligently informed, the pollution cause is traced back in real time, control measures can be effectively recommended, and the ecological environment intelligent supervision level is improved. The technical problem that the existing method and technology cannot perform intelligent monitoring management on the drainage basin efficiently, quickly and accurately is solved.
