Therefore, if the carbon sink can be increased autonomously in China, the industrial development of China can be promoted, and the international influence of China is improved.
Artificial upflow is considered to be one way in which carbon sequestration may be increased. The artificial upflow is to mention the sea water which is deep in the ocean and rich in nutrient salt to the ocean surface layer. Sunlight and nutrient salts are required for algae propagation, and in a euoptical layer, the main factor limiting algae propagation is the nutrient salt. Thus, when deep sea water rich in nutrient salts is brought to the euglene layer, algae suddenly burst and proliferate, and photosynthesis thereof absorbs a large amount of carbon dioxide, thereby increasing carbon sequestration. The area where the seawater lifted by the artificial upflow is located is called a plume area, and the salt concentration and the chlorophyll concentration of the plume area are analyzed, so that the specific situation of algae outbreak can be known, and the efficiency of increasing carbon sink can be improved.
