<h1 class="pgc-h-arrow-right" data-track="1" > in 2015, the United States paid close attention to the construction of an island in the South China Sea, when we were about to build an island, there were many people who doubted whether because of other interference, forced to stop under pressure, in fact, there is an official answer to this question, in short, you can fill in again, but it is not necessary. </h1>
The sustainable development of the country depends on its own comprehensive national strength and competitiveness, the national territory is an important factor in highlighting the comprehensive national strength, many countries in order to increase the territory, they choose to reclaim the sea in the coastal areas to create land, and even directly build islands. Island building is the filling of some uninhabited reefs, hoping to expand the territory, while building military facilities, residential buildings, ports, etc. to develop the national economy.

Among the islands and reefs that we effectively control in the Spratly Islands, Mischief Reef and Subi Reef are 5.6 and 4.3 square kilometers respectively after blowing and filling, ranking first and second, and have not continued to fill, many people may ask, why is there still a part that can be filled, but it is no longer filled, since the reef is built on the island, it is such a favorable thing, why don't we fill a larger island, how long does it take for the reef to fill 100 square kilometers?
In 2015, the United States paid close attention to china's sand blowing in the South China Sea to build an island, when our island was about to end, there were many people who doubted whether they were stopped because of other interference and pressure, in fact, there is an official answer to this question, in short, you can fill in again, but there is no need.
The first reason is that the current construction area has met the needs of our country, and after the filling of Mischief Reef to become the largest island in the South China Sea, China has established a large airport here, which can not only provide passenger aircraft to take off and land, but also for fighter jets. After the subi reef was filled and built, it not only had an airport, but also planted a large number of coconut trees, which increased the greening effect and was also the administrative center of Nansha. At present, the initial construction of the two islands has been completed, and what needs to be done later is to strengthen and improve, so it will not be filled for the time being.
The second reason is related to the geography of the island reef, Subi Reef is an isolated circular reef, shaped like an irregular shape of a pear, only when the sea is low tide, the surface is exposed, the water outside the reef is turbulent, there is no entrance, it is not convenient for large ships to pass, so although its geographical location is crucial, it is not suitable for large area filling.
Mischief Reef, on the other hand, is oval in shape, its top is made of coral, the surface of the water is higher at low tide, and there is a lagoon inside, covering an area of 36 square kilometers, with three gates, which can be used for large ships to navigate, and is a natural haven. But before it was built, the country had already made plans in advance. At that time, the planning map showed that the demarcated construction area was shallow water, and the deep water section would not be filled. Because the low reef part of the east is not filled, it can be conducive to the balance of the sea, and the lake water is clean, which proves that the planning is not all filled.
Subi Reef and Mischief Reef began filling on January 25 and January 26, 2015, respectively, and the initial filling was completed on June 16 and June 8 of the same year, taking nearly five months, equivalent to 1 square kilometer per month. According to such a calculation, if the filling of 100 square kilometers is to be close to 10 years of time, for the national economic construction, 10 years to grind a sword, not too long, of course, this is our conjecture, if you want to continue to blow sand to build an island, or face many problems, such as the adjacent countries of the Nansha Islands, involving the issue of ownership, will not be silent, or in the process of building the island, the impact on the cultural terrain, as well as the protection of marine resources.
Nowadays, the technology of sand blowing and reclamation in China has far exceeded many countries, so in the construction process, we mainly consider the natural environment around the island reef without too much impact, through scientific natural simulation methods, to achieve the natural formation of the island, such as after the completion of the surrounding environment has a certain damage is the need for time to improve the repair, at present in the Nansha Islands area there are still some islands and reefs can continue to develop, so subi reef and Mischief reef remaining part of the temporary is not filled, but also has no impact.
