How much china's territory is, everyone will answer in unison: 9.6 million square kilometers, can not be said to be wrong, after all, it was the first measurement of the approximate value of the results, but also the authoritative evaluation at that time. But this is not an exact number.
Among them, the precise number should be 963.4057 square kilometers, accounting for about 1/15 of the world's total land area, ranking third in the world, in 2017, China added another 290,000 square meters of territory, which makes the US military helpless.
How did the territory increase? The answer is land reclamation, and in 2017, China carried out a series of construction projects on islands and reefs in the South China Sea.
Reclamation in the South China Sea
China's ability to carry out large-scale reclamation in the South China Sea is inseparable from the Tian Whale, which is "127.5 meters long and 23 meters wide, and is said to be equipped with a variety of current international most advanced dredging equipment, with a total installed power of 20,020 kilowatts, of which the power of the grinding knife reaches 4,200kw, with the most powerful excavation system in Asia in the use of dredgers, not only dredging clay, dense sand, gravel, but also excavating rocks with a compressive strength of up to 40 megapascals.
The ship is also equipped with three high-efficiency mud pumps, with a strong ability to blow and fill the land, in the implementation of the blow filling operation, the "Sky Whale" can discharge the mixture of sea sand and seawater at a speed of 4500 cubic meters per hour to 6000 meters, and the sea sand blown and filled every day reaches more than 100,000 cubic meters. The "Sky Whale" also has a barge function, which can transport the excavated silt and gravel blocks to other places through barges, greatly expanding the dredging range and having the navigation capability of unlimited navigation areas.
Of course, this ship alone will not work, and it will take other large-scale equipment, efficient construction teams and systematic planning to achieve this.
According to the data, in 2017, China built 290,000 square meters of new facilities on islands and reefs in the South China Sea, including underground storage areas, administrative buildings and large radar facilities. The facilities that China has built on islands and reefs in the South China Sea are mainly to meet various civil needs, so as to better fulfill China's international responsibilities and obligations in maritime search and rescue, disaster prevention and mitigation, marine scientific research, meteorological observation, ecological environmental protection, navigation safety, fishery production services, etc., as well as to meet the necessary military defense needs.

Most of the various artificial islands built by various countries are in two situations: one is that cities with tight land use build islands in urban coastal areas to increase urban development space; The other is to reclaim the sea to build transportation facilities such as airports or deep-water ports. These two kinds of artificial islands account for the vast majority of the form of island building, and these two kinds of artificial islands are mostly in the shallow coastal waters with developed economy and large population density, and the distance from the mainland is very close, and the construction is more convenient.
And like China,000 large-scale reclamation of islands in the South China Sea, it belongs to the distant sea islands, which is relatively rare in the world, especially the island-building technology used by China is more advanced in the world.
The South China Sea Island and Reef Expansion Project adopts the general technical idea of "natural simulation", imitates the biological debris such as the wind and waves in the ocean, carries coral grit, and continues to accumulate on the comprehensive dynamic balance point of shallow water reef flats, forming a stable tidal accumulation body, and gradually evolving into a natural process of sea oasis, using large suction dredgers to suck and pump loose coral grit in the lagoon, blowing and filling on the inner reef flat, forming a tidal land base platform, building part of the facilities, and through the atmosphere, rainwater, Natural forces such as leaching accumulation of sunlight, supplemented by artificial acceleration measures, will produce the ecological effect of desalination- curing - weathering - greening, and gradually form a green ecological environment for coral reefs.
In addition to ecological landmaking, on the island, China has also begun a large-scale greening project, it is not easy to plant trees on the island, high temperature, high humidity, high salt, saplings, soil must be transported from other places, watering trees must also be desalinated seawater. As of 2017, Sansha has planted more than 2.5 million trees, which has played an important role in protecting and improving the ecological environment of the island and reef and stabilizing the shape of the island.
China's land reclamation in the South China Sea has naturally caused dissatisfaction in the United States, but the US military has no choice, and the US "National Interest" has published an article helplessly saying that with the increase in the number of modern warships of the Chinese Navy, the US Navy will lose its advantage in the Pacific.
summary
Of course, we do not care about the attitude of the United States, with the successful launch of the Tiankun, China's reclamation project in the South China Sea will achieve greater results in the future, the Tiankun "the whole length of 140 meters, the width of 27.8 meters, the depth of the type 9 meters, the maximum digging depth of 35 meters, the maximum power of the wringing motor up to 7500 kilowatts, dredging 6000 cubic meters per hour." These figures determine that it is the largest self-propelled suction dredger in Asia.
It is equipped with the first power of the excavation system in Asia. The total power of the grinding knife motor is 6600 kilowatts, the maximum power is 7500 kilowatts, and it is installed with the most advanced intelligent integrated control system of the suction dredger in China. With this "brain", it is possible to display the dredging three-dimensional soil quality in real time, calculate the tide level, manage energy efficiency, and intelligently automate dredging.
With the continuous development of China's scientific and technological strength, it is believed that in the near future, the South China Sea will have a new maritime capital.
