Variation characteristics and influencing mechanism of CO2 flux from lakes in the Badain Jaran Desert: A case study of Yindeer Lake

Carbon sequestration levels in lakes are often underestimated despite being vital for the comprehensive analysis of CO2 budget and significantly influencing inland lakes in arid areas. In this study, the eddy covariance (EC) technique was used to measure CO2 flux for six consecutive years during 201...
