Abstract:

The karst process is important composition of global carbon cycle because it can take-up CO2 from atmosphere. To calculate karst carbon sequestration (Kcs) is useful to complete the theory of global carbon cycle. By the karst dynamic system theory, the Kcs is controlled by groundwater discharge and HCO-3 mass concentration. The Banzhai River catchment, located in Maolan National Nature Reserve of Guizhou, was chosen as the study area. By the auto-monitoring technique, the discharge and water chemistry data of Banzhai River catchment were obtained. Based on the analysis of relationship between discharge, HCO-3 concentration and karst carbon sequestration under different precipitation conditions including storm period, no/weak precipitation period and dry season.Kcs has positive correlation with discharge and negative correlation with HCO-3 concentration. It shows that the discharge of catchment is main factor of Kcs rather than HCO-3 concentration. The larger discharge of karst catchment, the larger Kcs from atmosphere.

Key words: karst carbon sequestration, precipitation, groundwater, Baizhai River catchment
