| 摘 要： | 峰丛洼地表层岩溶动力系统与土壤CO2密切相关．土壤C02体积分数变化受气温和降雨影响，其季节变化特征表现为：冬季的波谷、夏季的波峰交替出现，秋季出现次波谷和次波峰．受降雨影响，表层岩溶动力系统运行强度春、夏季较强，秋、冬季较弱．从冬至夏，在土壤CO2逐渐增多时，系统溶解、转移碳的能力也逐渐增强．在土壤CO2和温度双重支配下，系统由冬季的沉积趋势转为春、夏季的溶解趋势．

| Abstract: | Epi-karst dynamic system is related closely with CO 2 content in soil. Temperature and rainfall dominate the seasonal change of CO 2 content in soil. The CO 2 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 CO 2 content in soil from winter to summer. With the control of CO 2 content and temperature, the sedimentation-dissolution trend of the system changes from sedimentation trend to dissolution trend from winter to spring and summer. |
