- Abstract:
-
Utilizing stable carbon isotopes to trace the nutrient circulation and energy flow in ecosystem, trace the dynamics of carbon transfer in ecosystem quantitatively, and clarify the ecosystem carbon cycle and its driving mechanism has become an important technique for the study of the carbon cycle of ecosystem. These studies cover carbon sources and assimilation in ecosystem determined by stable carbon isotopes, carbon transfer and fixation in plant-soil system, organic carbon transfer processes in deep soils, distribution characteristics of δ13C values in different types of grassland, as well as identification of carbon sources and contribution of components to ecosystem by isotope model. For providing an investigated reference for the driving mechanism of carbon cycle inecosystem and the response mechanism of global climate change to carbon flow, we reviewed the utilization methods and key technologies of stable carbon isotopes in grassland ecosystem. Meanwhile, stable carbon isotope technique is a rapid, accurate and efficient measurement, and hardly affects the function of ecosystem. Stable carbon isotope techniquecan provide credible supports for studies on carbon flow in ecosystem, vegetation change, and source determination and contribution proportion of carbon in ecosystem.
