Spatio-Temporal Variation of Air CO2 Concentration in Baojinggong Cave, Guangdong, China
摘要
Abstract
Monitoring of air CO2 concentration of Baojinggong Cave was carried out from December 15, 2011 to April 15, 2013. The results indicate that the cave air CO2 concentration showed notable spatial and seasonal variations. Monthly CO2 concentration of cave air varied from 201×10-6 to 3450×10-6 with an annual average of 1018×10-6. The CO2 concentration was higher in summer (from May to Octomber) and lower in winter (from November to next April). The sites closer to cave entrances, affected by strong cave ventilation, had lower CO2 concentration. The variation of cave air CO2 concentration was mainly influenced by cave ventilation and changes of vegetation respiration and soil microbial activity, which in turn were associated with changes in climate and environment. In addition, the special structure of Baojinggong Cave and tourists also contributed to the variation of cave air CO2 concentration.关键词
