LIFE-CYCLE MODEL OF TERRESTRIAL CARBON EXCHANGE
Leonid L. Golubyatnikov
and Yuri M. Svirezhev
Summary We present here a terrestrial carbon cycle model based on a scheme of the phytomass change which is continuous in time. The experimental information about net primary production, living and dead phytomass, and soil organic matter for various ecosystems is used for calibration of the model. The suggested model enables to characterize terrestrial 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. Intensity of the total exchange carbon flux for this territory is evaluated. The obtained results allow to conclude that the given territory is the sink of carbon. Download (PDF) |
