An algorithm has been developed for the simulation model of carbon behavior in herbaceous communities of various types, both autonomous and as a part of complex phytocenoses. The influence of external factors is taken into account, such as solar radiation, precipitation, air temperature, clouds, and wind speed. The dynamics of soil moisture level and temperature are reproduced. The algorithm can be modified, depending on the discreteness of consideration of the simulated processes. The algorithm is tested in modeling the dynamics of the phytomass of a community of ground elder (Aegopodium podagraria L.) that is dominant in the herbaceous cover of the ground elder oak grove on dark-gray forest soil. The EcoGrass model is used to conduct numerical experiments to study the impact of the potential global climate change and consumption of phytomass by animals on the productivity of this community. Threshold values of influence factors have been determined upon reaching which the normal functioning of the community is disrupted. [ABSTRACT FROM AUTHOR] |
