高分辨率实时监测技术在岩溶碳汇估算中的应用——以板寨地下河监测站为例

岩溶作用对大气CO₂起到汇的作用，其量级的大小受岩溶水的排泄量及由岩溶作用产生的无机碳浓度两方面的影响。基于贵州茂兰国家级自然保护区板寨地下河监测站的监测数据，对岩溶碳汇过程及其影响因子进行了分析。结果表明，板寨地下河流域岩溶年碳汇量约为353 t C，不同时间尺度的岩溶碳汇强度与流域的排泄量之间均存在良好的线性关系。因此，能否准确监测岩溶地下河的排泄量是岩溶碳汇估算的关键。由于岩溶区水循环季节变化幅度较大，具有实时监测功能的监测站在岩溶碳汇评估中显得十分必要。

The Utilization of Real-Time High Resolution Mornitoring Skill in Karst Carbon Sequestration: A Case of the Station in Banzhai Subterranean Stream Catchment

The karst process is carbon sequestration for atmosphere CO2. Karst carbon sequestration (KCS) value depends on the discharge of karst catchment and inorganic carbon concentration of water body. Based on the data from the mornitoring station on Banzhai subterranean stream located in Maolan National Nature Reserve of Guizhou, the influcent factors of KCS have been analyzed. It shows that the KCS is about 353 t C per year in the catchment of Banzhai subterranean stream, and there is good liner relationship be...
