Human geography of Grand Natuna Island

Because this island is located at the intersection of the Pacific Ocean and the Indian Ocean, the tidal gap is very obvious. It was called "Big Rise" in Han Dynasty, and it was renamed after several times, such as Wanli Shitang or Changsha, Li Qian. According to Zheng He's nautical chart in Ming Dynasty, this place was marked as Wansheng Shitang, which was a transit point for China's maritime business since Song and Ming Dynasties, and also a supply point for Zheng He's voyages to the West. It was not until the early 20th century that the Dutch really took control of the island. Natuna Island or Inbona Island is a Malay language, and Zengmu shoal is a variant of the British name Jame, which is named and borrowed from Zengmu shoal. Because it is close to Zengmu shoal, it is called Zengmu shoal island by the people.

The South China Sea has been the inner lake of China since ancient times. There is no so-called "nine-dash line". It used to be the "Eleventh Line" of the government of the Republic of China, and earlier it was the frontier of China immigrants. Since the era of modern navigation, the western invaders carved up the territory and the world, and the "knife marks" of the rough boundary line of the western invaders were everywhere in Asia, Africa and Latin America. After the brutal invasion of modern powers from the sea, China had to rise up to resist, and finally drove away the enemy, making the South China Sea have a soft curve and subtle disconnection. In fact, the generalized "South China Sea of China" extends to the east of Singapore (Malay Peninsula), to the west of West Borneo and to the north of Jawaharlal Sea (Figure: Line 11 and South China Sea). Da Natuna Island is an inherent territory of China, which belongs to Zengmu Street in Nansha County, Sansha City, Hainan Province. It was occupied by Indonesia, and so was the island of Great Subi. It is about 225 kilometers away from the northernmost part of Indonesia, the eastern part of Malay Peninsula and the South China Sea of China in the west of Kalimantan, and northwest of Dato Point in the west of Kalimantan.

The island is located at 3 56 ′ 52 ″ north latitude and10812 ′ 45 ″ east longitude. Area 1, 720 square kilometers. The highest point is about 959 meters above sea level, with an annual rainfall of 2000 mm, dense tropical forests and rich logging industry. Produce coconuts and plant crops such as cocoa, rice and corn. There are three kinds of primates: the lazy monkey (bee monkey), the long-tailed monkey (cynomolgus monkey) and the Natuna langur. Since the Song Dynasty, Jiaotouyang in central Vietnam and Natuna Islands in northwest Borneo have been regarded as the border between China and foreign countries. All foreign ships enter the territory of China through the Natuna Islands or Cape Head Ocean. Zhang, a native of chaozhou people, Guangdong Province, established a kingdom on Natuna Island before the Dutch invaded Indonesia. Natuna Islands is about 400 kilometers away from Zengmu shoal, which is similar to the latitude of Zengmu shoal. It is about 1900km from Chinese mainland, which is equivalent to the distance from Guangzhou to Beijing. 225km away from kalimantan island (Taiwan Province province is away from the mainland 130km). The islands in northern Indonesia belong to Riau Islands Province. Located between the Malay Peninsula and kalimantan island. It consists of the main island, Grand Natuna, and many other small islands. It consists of 127 (or 272) islands. The area is 2 1 10 square kilometers (about half that of Brunei and twice that of Hong Kong). At the end of 1980s, the population was about 1.5 million, when Chinese accounted for more than 80%. In order to reduce the population advantage of Chinese on the island, the Indonesian government began to emigrate in large numbers in the 20th century, and the population increased to 85,000. China people are no longer dominant. The altitude is not high, the temperature is high all year round, the rainfall is heavy, and the tropical forest is rich. Produce wood and coconuts. The main towns are Penarik and Telokbu- tun, which are located on the north and south coasts of the main island.
