China Construction Island

Located on the southwest side of Paracel Islands, it is a sand island developed on the reef. Zhongjian island is called Luodao by fishermen because it is famous for producing horseshoe snails. Located in the southernmost part of Paracel Islands, when it was halfway to Spratly Islands, it was also called "halfway". In 1946, China sent warship "Zhongjian" to take over the island, so it was renamed as Zhongjian island. Zhongjian island is a sand island developed on the reef. There are high sand dikes around and depressions in the middle. It is not very obvious and often has water. The water depth is 0.5m. The whole island is not high above sea level, with an average of only 2 meters, slightly round, 1200 meters long and 1000 meters wide. Sand island is 3 meters above the sea level at low tide and 1 meter above the sea level at high tide; its area is 1.5 square kilometers at low tide and only 0.85 square kilometers at high tide. Influenced by the northeast monsoon, the sand dike is higher in the northeast. When the typhoon passes through, the high tide can submerge most of the island, so the terrain changes greatly, showing the characteristics of transition from sandbank to sandbank. As the island is often flooded by the sea, it is difficult for vegetation on the island to grow naturally. There are seabirds perching on the high ground, so there is a layer of bird droppings. Due to the large and thick sand body and less bird manure pollution, clear springs are easy to obtain, especially in rainy season. Fresh water can be obtained by digging 2 feet. Zhongjian island is richly endowed by nature in the most west and south of Paracel Islands. The whole island is covered by coral, shell and white sand, and there is no vegetation. In the 1970s, coconut trees and loquat trees were planted. It's a four story building.

China Construction Island

Zhongjian island is located at the southernmost tip of Paracel Islands in Hainan, China. It is 50 km southwest of Huaguang reef, 90 km from Jinqing island to Yongle Island, and 178 km from Yongxing Island, Xisha. China's fishermen, commonly known as "Lo Dao" or "halfway", are now commemorating the 1946 China government sent to receive the Paracel Islands Zhongjian No. Some say it belongs to Yongle islands, some say it belongs to Xisha isolated islands.

More than 2 meters above sea level, the land area has shrunk from 1.5 square kilometers to 1.2 square kilometers due to wind and waves. Typhoons and spring tides often submerge most of the island. At high tide, Zhongjian island was only the size of two football fields

014 square kilometers, about one percent of the low tide.

The reef is relatively large, about 7.5 square kilometers. The island is a gray sand island developed at the top of the platform reef. There are sand dikes around the island and shallow lagoons in the island.

Garrison: Xisha sea battle instructions are very important. Therefore, the Chinese mainland troops stationed in May 1975 were built. In 1978, 1 months later, the central island garrison was formally established. After the completion of the main building in September, officers and soldiers moved from the old ship to the island. On August 11, 1982, the Central Military Commission awarded the China Construction Island garrison the honorary title of patriotism and Love Island Tianya sentinel.

Tree planting: Zhongjian island is a famous desert island, Fire Island, wind island and sand island. In 1982, Zhongjian Island planted the first coconut tree. Through the long-term unremitting efforts of the officers and soldiers, it has a large green forest. The camp is surrounded by shady green trees, flocks of chickens and ducks, and three prevention vegetable fields and seasonal vegetables are always new.

Need for mangroves: the big typhoon in 2009 seriously damaged decades of tree planting achievements, and the two super typhoons in 2013 had greater destructive power on a large area. Moreover, the big wind and waves swept away a large amount of sand, and the island area was seriously reduced. Officials and soldiers on the island said that mangroves need to be planted, which is known as wave elimination pioneer and coastal guard.

Historical evolution

Hainan fishermen are commonly known as "snails island" (the island is rich in horseshoe snails) or "halfway up" (on the way to Spratly Islands). There are different opinions about its affiliation. Some say it belongs to Yongle islands, some say it is far away from Yongle islands, and it belongs to Xisha isolated islands with East Island and Langhua reef.

In 1935, the government of the Republic of China announced the name of tulaitang island;

In 1947, the government of the Republic of China announced the name of Zhongjian Island (commemorating the Chinese government's acceptance of Paracel Islands's "Zhongjian" warship in 1946).

In 1946, the Republic of China warship "Zhongjian" took over the island, so it was renamed Zhongjian island.

In the battle of Xisha in 1974, China recaptured the control of Yongle islands in Xisha, which is an important basis for further controlling the isolated islands in Xisha. In May 1975, the Chinese mainland garrison was built in the abandoned commercial vessels for three years, and the 1 in 1978 of the island was formally established.

After the main building was completed in September, the officers and soldiers moved to the island from the old merchant ships. On August 11, 1982, the Central Military Commission of the Communist Party of China awarded the Zhongjian Island garrison the honorary title of "patriotic sentinel at the end of the earth".

In 1983, the government of the people's Republic of China announced its name as Zhongjian island.

In 2002, China Post issued the commemorative cover of "patriotism and Love Island sentinel".

geographical environment

position

Zhonqjian Dao is located at 15 degrees 47 'north latitude, 111 degrees 12' east longitude, and an island southwest of Paracel Islands (actually sand bar), 1850 meters long and 800 meters wide, with an area of 1.5 square kilometers. Some say they belong to the southwest end of Yongle islands, while others say they do not.

The northeast is 50 km to the southwest of Huaguang reef, 90 km to Jinqing Island, 69 km to Panshi Island, 178 km to Yongxing Island, 400 km to Hainan Island, and 330 km to Yangang, Vietnam.

the measure of area

Sand island is 2-3 meters above sea level at low tide and 1 meter above sea level at high tide. It once covered an area of 1.5 square kilometers at low tide and was only as big as two football fields at high tide

014 square kilometers, which is about one percent of the low tide period and one sixth of the Xisha tiny island. The standard 11 person football field covers an area of 7140 square meters (68m * 105m).

After the ebb of the tide, there are still patches of white coral sand. The whole island is coral shell sand. Due to the blowing away of the sandy land by the super typhoon in 2013, the area of sandy land has been seriously reduced.

Area change: due to the swallowing of wind, wave and tide, sand and soil loss, it has changed from 1.5 square kilometers to 1.2 square kilometers.

The sand island on the reef covers an area of about 1.5 square kilometers. Sand island is 2-3 meters high, and fresh water can be obtained by digging 2 feet of sand during rainfall, with large quantity and high quality. There are lagoons, covering an area of about 0.3 square kilometers. Some people say that it is difficult to transform a lagoon into a fresh water lake, because the spring tide is the sea water.

terrain

The terrain of Zhongjian island is low and flat, with an altitude of only 2-3 meters and a maximum of 2.7 meters. Strong typhoons are often submerged by sea water. There is a lagoon in the south of the central part with a depth of half a meter.

Zhongjian island is a sand island developed on the reef. There are high sand dikes around and depressions in the middle. It is not very obvious and often has water. The water depth is 0.5m. The altitude of the whole island is not large, with an average of only more than 2 meters, slightly round.

Sand island is 3 meters above sea level at low tide and 1 meter above sea level at high tide. In the past, the area of sand island was 1.5 square kilometers at low tide and only 0.85 square kilometers at high tide (it was reduced by 20% due to typhoon). Influenced by the northeast monsoon, the sand dike is higher in the northeast. When the typhoon passes through, the high tide can submerge most of the island, so the terrain changes greatly, showing the characteristics of transition from sandbank to sandbank.

hydrology

As the island is often flooded by the sea, it is difficult for vegetation on the island to grow naturally. There are seabirds perching on the high ground, so there is a layer of bird droppings. Due to the large and thick sand body and less bird manure pollution, clear springs are easy to obtain, especially in rainy season. Fresh water can be obtained by digging 2 feet.

climate

China Construction island is an inherent territory of China. The average temperature is above 31 ℃ and the sea breeze in four seasons is over 4.

typhoon

The biggest disaster of China Construction island is the frequent bad typhoons. The big typhoon in 2009 destroyed many achievements. In 2013, super typhoon "Butterfly" ravaged the South China Sea China Construction island is almost submerged in the sea, and the main building of the garrison, which is slanted by the typhoon by 7 degrees, looks like a "warship" floating on the sea from a distance. Late at night, the squad leader Wang Shaohui and the soldier were on duty in the bunker. Suddenly, the sea water poured in from the shooting hole. They immediately picked up their quilts to block the shooting hole. Due to the big waves, the quilts were pushed back several times. After a hard struggle, the shooting hole was blocked, but there was only a stone table in the castle. They sat on the stone table with the phone in their arms and the communication equipment in the middle. A bottle of water, a box of compressed biscuits, four chocolates, two people on the stone table to complete a day and two nights of persistence.

Geographical level

Zhongjian island is located on a large oval reef, 3.8 km long and 2.2 km wide, covering an area of about 7.5 square kilometers. Home island: in the center of the reef. Central area: it's the forest area. Look at the picture, it's about one twelfth of the island, about 0.1 square kilometers. Comparison: Shidao is only 0.08 square kilometers, Dongmen reef is 0.08 square kilometers, Chigua reef is close to 0.12 square kilometers.

Base point of territorial sea

In 1996, the Chinese government issued a statement on the scope of China's territorial waters, saying that seven points of China Construction island are the base points of China's territorial waters.

1. Zhongjiandao (1) 15 ° 46.5'n 111 ° 12.6'e

2. China Construction Island (2) North
