摘　　要：The role of microbes in the karstification process was determined based on the karst dynamics,CO2 capture,and carbonate deposition.A close relationship was found among microbial activity,karst dynamics and stability,and the carbon cycle in a karst ecosystem.More in-depth studies were needed to investigate the impact of microbes on karst dynamics within different eco-envi-ronments under natural conditions to determine the response of biological organisms to a changing environment,as well as the relationship between microbial organisms and the karstification process.The role of microbes in the karstification process was determined based on the karst dynamics, CO2 capture, and carbonate deposition.
