The origin of the name of Sumatran plus young plateau coffee

There are two theories about the origin of the name of Sumatra: first, it is said that the name of the island comes from the Sanskrit SamudraDvipa,samudra meaning "sea" and dvipa means "island", so in ancient times Sumatra was called Sumutrabhumi, meaning "brilliant and beautiful country". The synonym of this name is Sumatra Bumi (Sumutrabhumi), which evolved from Bumi in Sumatra. The ancient name of Sumatra is Andalas, which comes from Arabic. Hundreds of years ago, rubber trees were widely planted on the island, and people called it "Pazia", which means "rubber island" in Indonesia. After Indonesia became independent, the island won the laudatory name of "Island of Hope". Sumatra Indonesian writing Sumatera, English habit of spelling Sumatra. The name Sumatra has been recorded in Chinese ancient books for a long time, and the earliest description is the Yuan Shi Shi Zu Ji. Among them, it is recorded that Sumudu sent envoys to Korea until the nineteenth year of Yuan Dynasty (1282). Sumudu thorn is the earliest translation of the island in Chinese historical books, and it is also translated as Suimudu thorn in the History of the Yuan Dynasty. The Ming Dynasty set up the Department of consolation in Old Hong Kong here, and its name was frequently found in the official history of China and many of its classics, but the translation was not very uniform. in the Qing Dynasty, it was changed to Sumatra, and modern books have followed this translation ever since.

Topography

Sumatra runs northwest-southeast, intersects the equator in the middle, and consists of two areas: the Barisan Mountains Mountains in the west and the marshes in the east.

The western part of the mountain runs through the steep Barisan Mountains, stretching from northwest to southeast, stretching 1600 kilometers, with more than 90 volcanoes, of which the highest peak, Mount Kerinci, is 3800 meters above sea level. To the east of the mountains are alluvial plains, wide in the south and narrow in the north, with a widest point of more than 100 kilometers. There are many rivers, such as the Moussi River, the Batamhari River, the Indra Jiri River, the Gamba River and so on. Among them, the Hari River is the longest with a navigable capacity of 480km.

Jing² is the largest of the many mountains and lakes.

The Barissan Mountains are the continuous Cenozoic mountains of the Qinghai-Tibet Plateau, running through the island of Sumatra. Coal and gold deposits have been discovered in this area. The minerals from the volcano enrich the soil. The mountains are beautiful and charming, such as the area around Lake Lake Toba.

In the east, powerful rivers carry silt downstream, forming vast flatlands dotted with swamps and lakes. Although there is little arable land in the region, which is disadvantageous to agriculture, its importance to Indonesia's economic development should not be underestimated, because "oil is produced above ground and underground": Palm oil and oil.

Sumatra Island is located at the southeastern edge of the Eurasian plate, and the area south of the island is located at the edge of the Indian Ocean plate and is part of the Eurasian seismic belt. On December 26, 2004, the 10-meter-high tsunami triggered by the Indian Ocean earthquake swept the coastal areas of western Sumatra, causing serious damage. More than 80,000 people were killed in Indonesia, mainly in Aceh and North Sumatra provinces.
