Research on Carbon Source/Sink Measurement and Equilibrium in Wetland Tourism Sites—A Case of the Baiyangdian Wetland
Wetland ecosystems play a pivotal role in global carbon dynamics and represent a promising long-term strategy for mitigating global climate change.Utilizing a comprehensive dataset encompassing field research and remote sensing information,this study meticulously estimates the carbon sources and sinks within the Baiyangdian wetland tourism area,further calculating its overall carbon balance.Our findings reveal that among the various carbon emissions,those associated with tourism accommodation and transportation constitute the largest proportions,accounting for 36.03%and 35.79%of the total emissions respectively.In contrast,regarding carbon sequestration,the soil carbon sink capacity of the Baiyangdian ecosystem surpasses both the vegetation and water carbon sinks.Overall,the Baiyangdian wetland exhibits a net carbon sink status in terms of tourism-related carbon balance.However,it is noteworthy that the per capita carbon emission of tourists exceeds the general benchmark,suggesting significant potential for emission reduction initiatives.
