Carbon-Flow-Based Modeling of Ecophysiological Processes and Biomass Dynamics of Submersed Aquatic Plants

摘要: Abstract : Abstract: A dynamic simulation modeling approach to describing carbon- flow-based, ecophysiological processes and biomass dynamics of freshwater submersed aquatic plant species has been developed. The models describe major, carbon-flow-based four common how these are influenced by factors such as light, temperature, current velocity, dissolved inorganic carbon availability, oxygen concentration, human influences management measures (changes in turbidity, mechanical harvesting, grazing, flooding). model Vallisneria americana [model VALLA], Potamogeton pectinatus [POTAM], Hydrilla verticillata [HYDRIL], Myriophyllum spicatum [MILFO].
