The weathering of carbonate rocks consumes significant amounts soil CO2, contributing to both direct source reduction and the enhancement carbon sinks. This process holds substantial potential as a sink, making it critical strategy for achieving neutrality mitigating climate change. However, control mechanisms reverse assessment karst sinks, with CO2 core at input end karstification, are unclear. By comparing respiration its δ13C values between non-karst regions, we analyzed impact karstification on respiration. In this study, examined grassland (KG), woodland (KW), (NKW) in region identical conditions research subject, analyzing differences rate (RS), flux (SRF), isotope under different land-use types, them reveal sink reducing emissions. results showed that after change from KG KW region, annual mean RS SRF increased by 55.50% 20.94%, respectively. Additionally, contribution were approximately 8.2% higher than those KW. contrast, 25.14% 41.80% lower NKW, Furthermore, participation was about 8.9% NKW. Land use can significantly influence exhibiting highest capacity. Karst soils play crucial role atmospheric levels facilitating regional neutralization. Therefore, systems pivotal “land term” (source term, ELUC) global balance.
