The present disclosure refers to a method and a system of sudden water pollutant source detection by forward-inverse coupling, including: building an one-dimensional forward water quality simulation model of a river way according to acquired mechanical parameters and water quality parameters; according to the one-dimensional forward water quality simulation model of the river way, measuring and calculating each monitoring index by using an inverse optimization source-detection model; by constructing the one-dimensional forward water quality simulation model of the river way, using the inverse optimization source-detection model for measurement and calculation; and performing the Bayesian updating, in order to realize multi-information fusion. The present disclosure may reasonably control and use different observation information, and combine the redundancy or complementarity of multi-sourced information in space or in time to obtain consistent interpretation of the measured object, thus overcoming the uncertainty of the water environment, improving the accuracy of water pollutant source detection.

A method and system for ecological operation of total phosphorus (TP) export of a cascade hydropower station are provided. The method includes: integrating total power generation and TP export of the cascade hydropower station into a single operation objective, and obtaining an operation objective under different weight ratios; optimizing the obtained operation objective; and obtaining a water level operation process corresponding to total power generation and TP export under the current operation objective through the optimized operation objective. The present invention alleviates an ecological and environmental problem caused by the construction of the hydropower station from a water quality mechanism, and can be widely used, for example, in the ecological optimal operation of cascade hydropower stations in a river basin.
