Lake ecological hydraulic regulation and control method and system based on hydrological-ecological response relationship

The invention provides a lake ecological hydraulic regulation and control method and system based on a hydrological-ecological response relationship, and the method comprises the following steps: determining a research region, and constructing a training set and a test set; a time sequence prediction neural network model based on a graph structure is constructed, the training set and the test set are adopted for training and testing, and the tested time sequence prediction neural network model is adopted to predict hydrological data and ecological data of all collection points in future preset time; constructing a river and lake hydrometric hydrodynamic simulation model, and obtaining hydrological data and ecological data of at least M acquisition points by taking the hydrological data and ecological data of the at least N acquisition points as input; and screening scheduling schemes meeting requirements by adopting a decision-making method, and constructing a lake ecological regulation scheme set.
