Short summary
By modelling soil CO2 production, transport and surface exchange processes (e.g. biocrust photosynthesis, respiration and photodegradation), we simulated the large variation of soil CO2 emissions from sparsely vegetated dryland ecosystem. Based on the model, we studied the roles of different processes in regulating soil C emissions. The complexity of regulation processes implied possibly high non-linearity of C responses to climatic variation, climate change and extreme climate events.
