Multi-target dynamic water distribution method based on irrigation area canal system

The invention discloses a multi-target dynamic water distribution method based on an irrigation area canal system, which comprises the following steps of: collecting and initializing data, and eliminating incomplete data and repeated data based on a data cleaning mechanism; meanwhile, in consideration of the situation that too many gate operation times cause canal system water delivery loss and unstable flow connection in the water delivery process, constraints such as canal system water distribution flow constraint, maximum round period constraint, water balance constraint and superior canal diversion flow constraint are constructed, and three objective functions of dynamic water distribution are constructed. The models comprise a gate operation frequency minimization model, a canal system water delivery loss minimization model and a canal water delivery stability model; and setting a fitness function which comprehensively considers the three objective functions, searching a feasible solution which minimizes
