Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] The multi-objective parameter calibration method of the present invention draws lessons from the principle of the GLUE method, and is also based on the idea of the Bayesian algorithm (Zhang W T, George B. Arhonditsisa. 2009.A Bayesian hierarchical framework for calibrating aquatic biogeochemical models[J].Ecological Modeling, (220): 2142–2161), each time the sample with the best simulation effect is selected, and then the parameter set is updated according to the characteristics of the best sample, and several iterations are performed to finally converge the parameters to a small area , thus giving a response range based on parameter uncertainty. With each step of the iterative process, the likelihood function is basically in an increasing state (George B.Arhonditsis, Song S, Conrad L, et al.2007.Eutrophication risk assessment using Bayesian ca...
