Summary

We present here an approach to evaluation of the total exchange carbon flux by means of mathematical modelling. This flux is defined as a difference between carbon income into the net primary production and its emission from dead organic matter due to both biological and non- biological processes. We suggest the model which enables to determine functioning of forest and grass ecosystems as carbon sources or carbon sinks and to evaluate intensity of these sources and sinks. The model is applied for the European territory of Russia as a case study.
