| Effects of Typical Aquatic Plants on the Stability of Inorganic Carbon in Karst Aquatic Ecosystem |
| 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. |
