摘要

We describe the results of comparative analysis of the numerical experiments carried out by using two different approaches to modeling the biological components of marine ecosystems: “ordinary” and object-oriented. These results demonstrate that the character of the space distribution (patchiness) of the food resource on the lowest level of the trophic chain strongly affects the growth rate of the density of population on the next level and forms specific features of its space distribution which, in fact, affect the productivity of all levels of the trophic chain. The representation of phytoplankton (lowest level) in the model in the form a continuous field of passive admixtures creates more favorable conditions for the nutrition of the organisms consuming this resource. Therefore, in our calculations based on the “ordinary” procedure of modeling of marine ecosystems, the productivity of all its living components is higher than in the case of application of the object-oriented method. The indicated distinctions are especially well visible on the scales of about ten kilometers.
