Abstracts

An ecosystem model was developed for sizestructured phytoplankton dynamics of coastal bay. State variables of the model include major inorganic nutrients (NO2 - +NO3 - , NH4 +, PO4 3- , Si), size classes of phytoplankton (microphytoplankton (>20µm), nanophytoplankton (<20µm), two classes of zooplankton (mesozooplankton, microzooplankton), and organic matters (POC, DOC). The iconographic interface of STELLA model was used to facilitate construction of the dynamic ecosystem model. The ecosystem model was integrated with STELLA 7.0 using a 4th order Runge-Kutta method (a numerical variable time step). The developed method suggested that the dynamical model using STELLA software can be useful to study phytoplankton dynamics in the pelagic coastal ecosystem. Keywords: Ecosystem model, Phytoplankton, Zooplankton, STELLA.
