The present application relates to a kind of
water level rhythm calculation method for promoting
lake water aquatic
vegetation recovery.The present application is based on
lake water aquatic
vegetation growth model, carries out the analysis and controllable
water level discrete of different time scale under
lake water level regulation constraint condition, through the numerical test of different aquatic
vegetation distribution area and
biomass under the
scenario of typical hydro-meteorological conditions and
pollutant concentration in target period, establish vegetation
recovery evaluation model, the maximum
biomass and corresponding
water level of last period are used as initial value, the next period
simulation and evaluation are carried out, until the water level
rhythm that can promote the maximum
recovery of vegetation is formed all year round.The method of the present application uses restrictive water level under different needs as regulation constraint, fully considers the influence of wave, lake current and other hydrodynamic elements on
plant germination and growth under different water level conditions, uses different,
variable time step to simulate vegetation
biomass, can form the water level regulation
rhythm that can promote the maximum recovery of aquatic vegetation in controllable interval water level interval.
