According to the method, a time variable is introduced into the water bloom generating mechanism model, the water bloom generating mechanism time varying model is established, so that the method is suitable for simulating a water bloom generating process and can be used for water bloom prediction, and the problem that water bloom prediction based on a data driving model is not accurate enough, and a mechanism driving model cannot predict water bloom is solved.

Description

technical field [0001] The invention relates to a time-varying model optimization and water bloom prediction method for algae bloom formation mechanism in a lake reservoir, belonging to the technical field of environmental engineering. Background technique [0002] With the development of economy and society, water eutrophication has become a major global water environment problem. With the intensification of eutrophication in global water bodies, algal blooms in lakes are becoming more and more common. The outbreak of algae blooms has destroyed the biodiversity in the water body and seriously restricted the economic construction and social development. Therefore, in-depth research on the generation process of algal blooms and effective simulation and prediction of algal bloom outbreaks, an unconventional emergency, are of great significance for promoting water environment protection and technological progress. [0003] At present, the research on modeling process of algae...
