    Abstract
  • Ten sampling plots in different geological eco-environments were selected along the main stream and tributaries of the Changjiang River basin. Carbonic Anhydrase (CA) activity and Soil Organic Carbon (SOC) content in surface soils (0~20 cm) were studied and relationships between CA activity and SOC content were discussed. The results were as follows. (1) The CA activities in surface soils of karst areas were higher than those in non-karst areas (P<0.01). Different geological types and vegetation types resulted in different CA activities. (2) The plot GC in karst areas had the highest annual average SOC content (1.09%) while the plot WZ in non-karst area had the lowest annual average SOC content (0.29%). Moreover, the average surface SOC content in winter was significantly higher than that in summer (P<0.01). (3) Correlation analysis showed that CA activities in karst surface soils correlated positively with SOC contents in all seasons. The result of this paper lays a foundation for further studies on the role of soil CA in carbon sequestration in karst ecosystems of river basins.
