| 中文摘要:碳循环研究是全球变化科学中的研究重点, 其平衡问题已成为全球变化与地球科学领域的研究前沿和热点。“遗失汇”是全球碳收支研究的重点, 寻找和揭示其存在机理对研究全球碳循环具有重要意义。在全球碳循环研究中, 仅考虑海洋碳库和陆地生态系统碳库对全球碳循环的贡献, 然并未对地球岩石圈中碳酸盐岩碳库作充分评估。以袁道先院士为首的研究团队, 利用石灰岩溶蚀试片法(Carbonate-rock-tablet-test method)、水化学法(Hydrogen-discharge method)和扩散边界法(Diffusion Boundary Layer Model, DBL)首次估算了全球每年因碳酸盐岩溶蚀作用产生的碳汇量其约占当前碳循环模型中“遗失汇”的约1/3。 |

| Abstract:The carbon cycle research is the key point in Global Change Science. Its balance has become the frontiers and hot spots in the field of global change and earth science. Missing sink is the focus of the global carbon budget, finding and revealing the mechanism of its existence is of great significance to the study of global carbon cycle. In the global carbon researches, only considering the contribution of the ocean carbon library and the terrestrial ecosystem carbon library, but lack of adequate assessment for the carbonate carbon pool in the earth lithosphere. Re-search team headed by academician YUAN Dao-xian adopted the Carbonate-rock-tablet-test method, Hy-drogen-discharge method and Diffusion Boundary Layer to estimate the amount of carbon sequestration each year caused by karstification around the world for the first time, which account for one-third of the missing sink in the carbon cycle model. Modern kar-stology in China demonstrated karstification actively involved in the global carbon cycle. However, some scholars have cast doubt on the stability of karst car-bon sink thought “carbonate dissolution is only a process of carbon migration but does not produce carbon sequestration”. Yet aquatic plants are an im-portant part of aquatic ecosystems occupied the key interface of aquatic ecosystems, aquatic plants photo-synthesis is of vital importance to the primary pro-ductivity and the carbon biogeochemical cycles. |
