River lake water body quantity-quality coupling self-optimizing simulation regulation and control method

The invention discloses a river lake water body quantity-quality coupling self-optimizing simulation regulation and control method which comprises the steps that first, a water body quantity-quality coupling simulation model in a river lake zone to be regulated and controlled is established; second, according to the water body quantity-quality coupling simulation model and a current decision scheme, the simulated results of the water quantity, the water level and the water quality of the river lake zone to be regulated and controlled are obtained; third, the water quantity, the water level and the water quality are used as decision targets, an optimization decision zone of a river lake water body system is established; fourth, whether the simulated results of the decision targets meet the requirement of the river lake water body system at the same time is judged, and the current decision scheme is corrected according to the judging results. According to the method, the water quantity, the water level and the
