Abstract

Abstract

Epi-karst dynamic system is related closely with CO₂ content in soil. Temperature and rainfall dominate the seasonal change of CO₂ content in soil. The CO₂ content is low in winter when it is cold and dry while it is high in summer as it is hot and wet. There are a hypo-trough and a hypo-crest in autumn when there is a sudden increasing in rainfall. Epi-karst dynamic system is more active from spring to summer than from autumn to winter, because rainfall is focus in spring and summer. The system transfers more and more carbon with the increase of CO₂ content in soil from winter to summer. With the control of CO₂ content and temperature, the sedimentation-dissolution trend of the system changes from sedimentation trend to dissolution trend from winter to spring and summer.
