Tourism characteristics of Lake Doba

Duba Lake, known as the "Pearl of Sumatra Highlands", is located on the mountain at an altitude of 906 meters. It was formed by a volcanic eruption 75,000 years ago that caused the top of the mountain to fall. Length 100 km, width 3 1 km, area 1. 145 km2. It is the largest lake in Southeast Asia, with a water depth of about 45,000. The first impression is Lake Doba, which is surrounded by lush green mountains. People often associate it with the lake area in Switzerland, and its beauty is fascinating. Overlooking Lake Doba from the top of the mountain, I saw simple and quiet villages built by the water and scattered around the lake. The crops near the house are full of vitality, with clear lake water in the green, distinct and competitive, and the colors are extremely saturated and bright. Looking into the distance, the vast lake is faintly visible in the mist on the far side. On the mirror-smooth lake, the ferry passes quietly, leaving only a crack. In the quiet and deep lake Doba, you can choose to lie on the grass and watch it fascinated, or you can choose to swim in the lake and touch it passionately. Besides, you can sit on speedboats, motorboats and pedal boats … and get close to it happily. Located in the northern part of Sumatra Island, Indonesia, Mada Plateau is the largest freshwater lake in Indonesia, a world-famous plateau lake and a famous tourist attraction. Lake Doba is formed by faults. The lake is diamond-shaped, 87 kilometers long and 26 kilometers wide. The lake is 906 meters above sea level, with an area of 1.300 square kilometers and the deepest part of the lake is 529 meters. Lake Doba was originally an ancient crater site, which was formed by long-term water accumulation. The cliff of the lake fault is 600 meters, and below it is a narrow plain. In the middle of the lake, there is an island about 7 kilometers long and 2.5 kilometers wide, named Samos Island, which accounts for about 1 of the whole lake area. There is a long and narrow artificial dam connecting the west bank of the lake. The lake cliff is as high as 600 meters. The mountains on the island are undulating, and only the periphery of the lake is relatively flat. There is water in the mountains and mountains in the water, which is a wonderful natural landscape. The island has Cedar Boutal Mausoleum of Aceh Dynasty, which was built about 250 years ago. It is made of stone, high above the ground, and the body is placed directly in the stone. There is a stout "holy tree" in front of the mausoleum. There are many protruding roots on the ground near the tree, and there are boards in the roots. Visitors can sit here and listen to the history and allusions of the mausoleum. There is a stone statue of Siddhartha in front of the mausoleum and a princess in the back. There are also some stone statues near the mausoleum, where the ancient Bataks made wishes and prayed to God. On Samos Island, there is a traditional Bartak longhouse with a high roof and upturned ends, which looks like a horn. The residents here believe that buffalo horns can ward off evil spirits. There are stone tables, chairs and instruments of torture in the village of anbari Tower on the island. It was once the place where King Baltac and officials held meetings and tried cases, and criminals were punished here. There is an open-air exhibition hall in Simando village on the island, which houses the antiques of the kingdom of Sida uruk and the residence of the king, Rumabolo. Ten buffalo horns are hung on the pillars of the house, indicating that ten generations of kings have lived and lived here. In the delta area of northern Sumatra, there is a beautiful lake-Doba Lake, which was formed by volcanic eruption. It is the largest and deepest volcanic lake in the world. It is 900 meters above sea level, 90 kilometers long and 3 1 km wide, with a water area of 1 145 square kilometers. The deepest place has not been verified, and it is estimated to be between 450 and 800 meters. There is an island in the middle of the lake, as big as Singapore. People from all over the world will gather in Doba Lake to enjoy the beautiful scenery and experience the tranquility. Some people can sail on the lake, some can swim, some can water ski, some can climb mountains, some can swim, and some just relax.

At the northwest end of Lake Doba, there is a famous waterfall called Xibibibi Waterfall, with a drop of more than 300 meters. The water from the waterfall flows out of the cave and into the lake. Here, lakes and mountains, silver waterfalls flying, very spectacular. There are many volcanoes around Lake Doba, among which Sibaya volcano and Sennabu volcano are over 2000 meters above sea level. There is light smoke spewing out of the mountain pass, white clouds are around, and the scenery is charming. Pine forests are dense on the hillside. The famous summer resort Mada is 1400 meters above sea level, with steep peaks and lush trees. In the nearby village of Pemartin Purba, there is a long king's palace in Simalengan, which was built more than 200 years ago. The whole building is made of trees and ropes without nails. There are 12 diagonal corners on the wooden frame in the center of the entrance, and each diagonal corner represents a dynasty. There is a small room in the palace as the king's bedroom, and there is a walkway in the middle of the other big houses, about 2 feet high on both sides, which is the residence of the concubines. Every concubine has a small place and a cooker, which is where she eats. Dongying fishing village in the northwest of Doba Lake is quiet and beautiful, and is called "Xanadu". There is a small park opposite the village, the lake bay, with water on the back and sparkling cliff walls, which is absolutely attractive. Around the lake, there are highways connecting the towns on the plateau, leading to Medan and Fifteen Cliffs on the east and west coasts. There is a fishing village in the northwest of the lake. Because the average elevation of Mada Plateau where Doba Lake is located is 1000 meters, and the elevation of the lake is 906 meters, the air here is fresh and the climate is cool. In addition, the lakes here are surrounded by mirrors and strange peaks, and various tourist facilities are constantly being built. Lake Doba has become a rare summer resort in Indonesia, a tropical country with hot summers all year round. The map of Lake Doba shows a northwest-southeast trend, with the middle crossing the equator, and consists of two areas: barisan mountains in the west and the marshland in the east. Balishan Mountain Range is a continuation of Cenozoic Mountain Range in Qinghai-Tibet Plateau, which runs through Sumatra Island. Coal and gold mines have been discovered in this area. Minerals from volcanoes enrich the soil. These mountains are beautiful and charming, such as the area around Letoba.

In the east, powerful rivers bring mud downstream, forming a vast flat land, which is spread all over swamps and lakes. Although there is less arable land in this area, which is unfavorable to agriculture, its importance to Indonesia's economic development cannot be underestimated, because "oil is produced on the ground and oil is also produced underground": palm oil and oil.

In ancient times, most of Sumatra was covered by tropical forests, which used to be the habitat of precious animals and plants (orangutans, tigers, tapirs, flowers, etc.). Unfortunately, the corrupt atmosphere of the authorities and illegal forest development put these virgin forests in danger of being destroyed. Even the so-called "protected areas" have been cut down.

Lake Doba is located on the western edge of the Eurasian plate, and the northern part of the island is located on the edge of the Indian plate, which is a part of the Eurasian seismic belt. 65438+On February 26th, 2004, the 10-meter-high tsunami triggered by the Indian Ocean earthquake in 2004 swept through the western coastal areas of Sumatra, causing serious damage. More than 80,000 people died in Indonesia, mainly in Aceh and North Sumatra provinces. Lake Doba is a green island, with all kinds of tropical plants covering the whole territory and full of vitality everywhere. Overlapping mountains are submerged by virgin forests, smooth rivers are surrounded by tall and straight coconut trees, and cities, villages, fields and roads are immersed in green oceans. The green ocean and the blue sky constitute a harmonious and beautiful picture scroll, which has become an eternal and beautiful scenery of Sumatra Island, leaving a deep impression on tourists. There are more than 90 volcanoes in the western half of the mountain, and the highest peak is Ge Linzhi volcano, with an altitude of 3805 meters. The eastern half is plain, which is wide in the south and narrow in the north, and the widest point is about 100 km. There are many rivers, mainly Muxi River, Batayan River, Indra Giri River and Gamba River, which are navigable. Tropical forests are abundant, with a coverage rate of 60%.

Although Lake Doba has a long coastline, it lacks a natural harbor. The reason is that it is often attacked by "Indian Ocean Waves". A high shore wave pushes ashore in a long row, two rows or three rows, which is powerful enough to lift the fishing boat to the top of the wave, then turn over and fall. Due to the phenomenon of "beating waves in the Indian Ocean", Sumatra and Java have almost no natural harbors. The habitat of Sumatran tiger is mainly the tropical rain forest in Sumatra Island, and its range of activities depends on the density of prey and the size of habitat. The average distribution density is 5 tigers/100 square kilometers.

Sumatran tiger is the smallest of the existing tiger subspecies. The average length of male tiger is 2.4m, and its weight is120kg. The tigress is 2.2 meters long and weighs about 90 kilograms. Their small size enables them to pass through dense forests quickly. Sumatran tiger has dark orange fur and dense stripes, which is typical of tropical island tiger. Unlike cheetahs and lions living on the plains, Sumatran tigers in the rainforest must attack their prey by lurking. The main food of Sumatran tiger is water deer, wild boar, porcupine, crocodile, python, young rhinoceros and young elephant. The tigress is pregnant for about 103 days, and each fetus gives birth to 2-4 cubs. At birth, tiger cubs weigh about 2.2-3 pounds. At this time, the cubs have not opened their eyes and their constitution is extremely fragile. Female tigers need to protect their cubs from male tigers or other animals at all times. Ten days later, the cubs' eyes opened, and from 1 to the eighth week, they lived entirely on breast milk. About six months later, the tigress began to teach them predation skills. The longest life span of wild Sumatran tigers is 15 years, and that of captive Sumatran tigers is 20 years.

Sumatran tigers in captivity are mainly exhibited in zoos in Indonesia, North America, Europe, Australia and Japan. According to the estimation of Indonesian Zoo Association (PKBSI), there are more than 230 Sumatran tigers in the world, including 65 in Indonesian Zoo. European Zoo 100; Australia Zoo has 12 animals. There are 55 zoos in North America; There are two in the Japanese zoo. There are 32 males and 29 females in the Sumatra Tiger Protection Center in Java.
