How many aircraft carriers does China need to meet the contemporary world situation?

According to China's major military websites, China will spend $654.38+08 billion to build six aircraft carrier task forces by 2025, including two large conventional power carriers and four nuclear-powered super carriers. It is estimated that the service areas are Bohai Sea, Yellow Sea, East China Sea, South China Sea and the northeastern Indian Ocean. Perhaps China's existing purchase of aircraft carriers can ensure the safety of China's maritime rights and interests. (1)2 1 Century China's marine strategy is to build a "three seas and two oceans" strategy. From the time point of view, it is generally divided into four steps: First, before 2020, Taiwan Province Province will be recovered, the East China Sea will be controlled, and it will go to the Pacific Ocean; The second is to achieve complete control of the South China Sea around 2030; Third, around 2045, with the rise of military strength, gradually control the Sea of Japan, fundamentally kill Japan, and completely relieve my worries; The fourth is to go to the Indian Ocean in 2060. After the strategy of "three seas" and "two oceans" is realized, it is tantamount to putting three shackles on Japan's neck; For Indo-China Peninsula, an encirclement situation can be formed, and the purpose of making vassals by relying on the ocean can be achieved. From then on, China can gain an absolute dominant position in Asia, and truly become an important pole with great power in the world, which will have a far-reaching impact on world peace and development. (2) In 21century, China will set up four ocean-going fleets (1):① There are two bases: Qingdao and Keelung; ② Control sea areas: Bohai Sea, Yellow Sea and East China Sea; (3) Three aircraft carrier task forces; (2) Nanyang Fleet: ① One base: Hainan; ② Control sea area: South China Sea, Malacca Strait and Crater Isthmus; (3) Two aircraft carrier task forces; (3) Northwest Pacific Fleet: ① Establish a base in East Korea Bay in exchange for territorial replacement or major economic benefits: Tumen Jiangkou Naval Base; ② Control sea area: the Sea of Japan and parts of the North Pacific Ocean; (3) Two aircraft carrier task forces; (4) Indian Ocean Fleet: ① Establishment of bases: leasing Myanmar ports, establishing naval bases in the Bay of Bengal, and establishing temporary naval bases in Sri Lanka, Pakistan and Iran; ② Control sea area: North Indian Ocean and Persian Gulf; (3) Aircraft Carrier Task Force II. (5) Backstage offshore fleet: ① Two bases: Dalian and Shanghai; (2) Two or three carrier task forces can be used as the general carrier base of ocean-going fleet, and the fleet can be built to damage ships in turn. Suppose that China will set up 1 1- 12 aircraft carrier task force in the 2nd century. In fact, after 2050, China will set foot in the Arctic Ocean, the Central Pacific Ocean and the Western Indian Ocean for the first time, and China's long-term ocean strategy should be adjusted as necessary. (III) Prospect of China's Marine Strategy in 2030-2080 According to authoritative experts' analysis, 82% of glaciers in western China have retreated. It is understood that the water resources in northern China are decreasing day by day, especially the Yellow River, Huaihe River, Haihe River and Liaohe River. The surface water resources of Haihe River will decrease by 4 1%, and regional water shortage will also occur in some areas in the south. The trend of land desertification in some parts of North China has intensified, and the area of desertified land on the edge of agro-pastoral ecotone and oasis in northwest China has increased. At the same time, 82% glaciers in western China are retreating, and the national water supply has been threatened for a long time. Agriculture is greatly influenced by climate. It is predicted that by 2030, if corresponding measures are not taken, the overall planting production capacity of China may decrease by 5% to 10%. By the second half of 2 1 century, the grain output can be reduced by 37% at most; At the same time, the increase of temperature will lead to the expansion of agricultural pests and diseases, the extension of damage time and the aggravation of crop damage, thus increasing the application of agriculture and herbicides. In addition, climate change will aggravate the instability of agricultural water resources and the contradiction between supply and demand. In short, climate change will seriously affect China's long-term food security. "Delta" has the highest survival risk. According to the assessment of relevant parties, the sea level along the coast of China has risen by an average of 2.5 mm per year for half a century, and by 12.5 cm in recent 50 years. The annual growth rate in Shanghai is even higher than 3.5 mm, and it has increased by 16cm in 50 years, far higher than the national average. It is predicted that by 2 100, the sea level in South China will rise by 60 to 74 cm. Sea level rise will not only increase the submerged area of coastal lowlands, but also aggravate the salt water intrusion in estuaries, and will also cause damage to coastal ecosystems, thus adversely affecting coastal fisheries. Faced with the threat of flood, seawater intrusion, land erosion and severe tropical storms, cities in the Yangtze River Delta, the Pearl River Delta and the Yellow River Delta will probably become the areas with the highest survival risk in China. It is the general trend for China to go to the ocean and develop marine green energy as much as possible. The opening of the Tumen River estuary ensures the smooth flow of China's new routes in the Arctic Ocean in the future; The opening of the Indian Ocean Sea Passage will ensure the convenience of China's oil and gas resources passage and trade, ensure that China's status as an Asian water tower will remain vibrant forever, and ensure that desertification in northwest China can be partially alleviated. Therefore, after China becomes the most powerful country in the world, it must do something in energy conservation, environmental protection and world resource allocation, and it is natural to moderately expand the scale of China's ocean-going navy. At the same time, China should accelerate its March into deep space and make its due contribution to defending its status as a global power!
