A sensitivity analysis of an ecosystem model of estuarine carbon flow

摘要: Abstract The North Inlet Marsh-Estuarine System Model (NIMES) is a 19-compartment real-time deterministic ecosystem simulation model of intrasystem carbon flow and exchange between an estuary adjacent coastal water. A complete sensitivity analysis this with regard to POM, DOM nekton annual system net productivity was completed the functional relationship these behaviors perturbed parameters were determined by regression techniques. Simulated POM sea largely controlled offshore concentration, water column respiration gross marsh flora. estuarine-oceanic most sensitive perturbations in biomass changes flora microbial uptake. reflected migratory behavior subtidal benthic changes. as simulated showed high all processes which affected component primary production respiration. From analysis, scheme developed evaluate research needs for further development ecosystem.
