Seasonal variations and sources of dripping CO2 in karst caves: A case study of the Dafeng cave, Guizhou Province

  • Publish Date: 2021-06-25
  • The purpose of this work was to clarify the characteristics of CO2 changes and its sources in the dripping water of the Dolomite caves. Taking the Dafeng cave,part of the Shuanghe cave system,as the research object, monitoring, sampling and laboratory analysis were conducted to cave air CO2 concentration (pCO2(c)),soil CO2 concentration (pCO2(soil)),cave drip CO2 partial pressure(pCO2(w)),and cave dripping hydrochemical environment for 15 months(January 2016 to March 2017). Then principal component analysis was performed on each monitoring index using the statistical analysis method. Results show that,(1)pCO2(w) and pCO2(c)have obvious seasonal variations,which are characterized by summer-autumn> winter-spring. pCO2(soil)is affected by rainfall and cave ventilation,which is the main source of pCO2(w) in caves.(2)Water-rock interactions of osmotic water flowing through caves over the karst zone,especially the hydrochemical environment and its HCO3- change are one of the main factors affecting pCO2(w), an important contribution to the pCO2(w).(3)Using principal component analysis(PCA),the contribution of each factor to cave drip is as follows,HCO3->pCO2(s)>Soil 1#>pCO2(w)>Soil 2#. The contribution comparison of each factor to pCO2(w) is as follows:deep karst on the surface > soil air environment on the cave > cave air environment.(4)The conceptual model on the source of pCO2(w)suggests that during the rainy season,the rainfall is large,the soil is infiltrated quickly,the groundwater is fully replenished,but the stagnation time is short,the reaction with the surrounding rock is insufficient in the seepage zone,and the PCP process is weak, posing a big influence on pCO2(w),while the dry season is the opposite. These research results have certain theoretical and practical significance for the protection of cave stalagmites and stalactite sediments. It is of great significance to the development and utilization of cave tourism and the study of karst carbon cycle.
