The invention discloses a lake and reservoir inflow and outflow scheduling scheme optimization method and
system based on a three-dimensional hydrodynamic force-
water quality-water ecological model, and the method comprises the steps: firstly constructing a three-dimensional hydrodynamic force-
water quality-water ecological model of a target lake and reservoir, setting a scheduling constraint, a scoring constraint, a scoring
single item, and a comprehensive scoring weight by a
decision maker,
stratified sampling and one-dimensional uniform random sampling are carried out on each flow range of a water replenishing port, a flow outlet and a water suction pump
station which can be regulated and controlled manually according to scheduling constraints set by a
decision maker, and a plurality of inflow and outflow scheduling schemes are generated; and performing
big data mining on the model calculation results of all the access
flow scheduling schemes, performing comprehensive scoring according to the scoring
single item and the comprehensive scoring weight, and selecting the access
flow scheduling scheme with the highest comprehensive
score as an
optimal scheduling scheme for recommendation. The method has the advantages of high
simulation precision, flexible decision support, multi-target comprehensive balance and the like, and a scientific and efficient technical solution can be provided for lake and reservoir inflow and outflow scheduling.
