The urban lake eutrophication simulation method and the urban lake eutrophication simulation system effectively improve theprecision of a water quality remote sensing inversion result by utilizing the set modeling technology, assimilate the water quality remote sensing inversion optimization value and the FVCOM model, and effectively improves the lake eutrophication simulation and prediction precision.

Description

technical field [0001] The invention belongs to the field of lake water environment simulation, and more specifically relates to a method for simulating eutrophication of urban lakes based on FVCOM and remote sensing inversion. Background technique [0002] Urban lakes, as one of the important water sources carrying multiple functions such as urban water supply, industrial water, land irrigation, fish farming, scenic spot viewing, flood storage and sewage storage, etc., due to the extensive economic development model and the unreasonable operation of the sewage treatment system, the self-purification capacity of the water body For reasons such as poor nutrition, eutrophication pollution is increasing day by day. The eutrophication of lakes will cause many hazards, such as destroying the ecological landscape, reducing the species diversity and stability of the water ecosystem, threatening human health, and causing economic losses. It is necessary to study the eutrophication ...
