      摘要: 巖溶作用對(duì)大氣CO2起到匯的作用,其量級(jí)的大小受巖溶水的排泄量及由巖溶作用產(chǎn)生的無(wú)機(jī)碳濃度兩方面的影響。基于貴州茂蘭國(guó)家級(jí)自然保護(hù)區(qū)板寨地下河監(jiān)測(cè)站的監(jiān)測(cè)數(shù)據(jù),對(duì)巖溶碳匯過(guò)程及其影響因子進(jìn)行了分析。結(jié)果表明,板寨地下河流域巖溶年碳匯量約為353 t C,不同時(shí)間尺度的巖溶碳匯強(qiáng)度與流域的排泄量之間均存在良好的線性關(guān)系。因此,能否準(zhǔn)確監(jiān)測(cè)巖溶地下河的排泄量是巖溶碳匯估算的關(guān)鍵。由于巖溶區(qū)水循環(huán)季節(jié)變化幅度較大,具有實(shí)時(shí)監(jiān)測(cè)功能的監(jiān)測(cè)站在巖溶碳匯評(píng)估中顯得十分必要。

      Abstract: 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 between KCS and discharge at different time scales. Therefore, how to mornitor the discharge accurately is the key to KCS estimation. And the stations with real-time monitoring function are very important for KCS calculation because of strong seasonal variability of karst water cycle.
