Which country is the lowest basin in the world?

China! Turpan Basin - the lowest basin in the world, it is a typical graben basin, and it is also the place with the lowest terrain and the highest summer temperature in the country. Most of the ground is below 500 meters above sea level, and in some places it is lower than sea level.

The Turpan Basin of China.

The geographical coordinates are 89 degrees 11 minutes east longitude. Latitude 42 degrees 56 minutes.

The lowest point on land in China is located in Ayding Lake in the Turpan Basin.

Ayding Lake is located in Gaochang District, Turpan City, Xinjiang Uygur Autonomous Region, which is a closed intermountain basin on the south side of the eastern section of Tianshan Mountain in China, and is also the destination of surface runoff in the Turpan Basin. Ayding Lake is not only the lowest point in the Turpan Basin, but also the lowest point in mainland China. The surface of Lake Aydin is below sea level, and its lowest point is 161 meters.

Climatic characteristics. The Turpan Basin belongs to the continental desert climate, arid and hot, the annual precipitation is about 16 mm, the evaporation is as high as 3000 mm, the highest temperature in summer has been recorded, and the average maximum temperature in June and August is above 38. The temperature of the sand surface at noon is the highest, so it has been called "Fire Island" since ancient times.

The sunshine hours are long, about 3,200 hours a year, and the frost-free period is about 210 days. Due to the low air pressure in the basin, it attracts air currents to flow in, and it is also a famous "wind reservoir" in China. The spring storm blowing from Daban Castle reached 50 meters per second, and the strong wind blowing from the Qijiaojing once blew over the vehicle.

"Turpan" is the Uyghur word for "lowland".

Between 41°12 --43°40 north latitude and 87°16 --91°55 east longitude.

An olive-shaped mountain basin that is placed horizontally from east to west, surrounded by mountains. The basin is 245 kilometers long from east to west from the mouth of Alashan Gorge to the west mouth of Qijiaojing Canyon in the east. to the north is the foothills of Mount Bogda; It reaches the Kulutag Mountains in the south, and is about 75 kilometers wide from north to south. In the middle, the remnants of the Flaming Mountains and the Bortoula Mountains run through the territory, dividing the region into two halves, the north and the south.

The water surface of Lake Aydin at the bottom of the basin is 155 meters below sea level, which is the lowest basin in the world, and the second lowest place in the world after the Dead Sea of Jordan, which is 391 meters below sea level.

It is a unique warm temperate continental arid desert climate. Because it is located in the basin, surrounded by high mountains, the heat increases rapidly, and the heat dissipation is slow, forming the five characteristics of long sunshine, high temperature, large temperature difference between day and night, less precipitation and strong wind, known as "Huozhou" and "Wind Reservoir". The average temperature of the year is 14, the average temperature in summer is about 30, and the hot weather with the temperature higher than 35 is 99 days on average; Very hot days above 40, with an average of 28 days.

The characteristics of climate change in the four seasons are: spring is short, with an average of 61 days, early spring onset, and rapid warming; The summer is long, with an average of 152 days, and the temperature is very hot; Autumn is shorter, with an average of 57 days, and the temperature drops rapidly; The winter is short, with an average of 95 days, with light wind and sparse snow, good weather, and short cold periods. January is the coldest month of the year and July is the hottest.

The Turpan Basin is the lowest basin in the world, with geographical coordinates of 42°, 89°, the lowest inland basin in China.

In the eastern part of Xinjiang Uygur Autonomous Region, it is an intermountain fault basin on the southern slope of the eastern section of the Tianshan Mountains. It is bounded by Mount Bogda to the north and Mount Kuruk to the south, covering an area of about 20,000 square kilometers. In the central part of the basin below sea level, about 4,000 square kilometers are located, the surface of Lake Aydin is -154 meters, and the bottom of the lake is -161 meters.

Geographical characteristics of the Turpan Basin.

The climate of the Turpan Basin is extremely arid, with very little rainfall, and the ability of water to move things naturally is very poor, so the sediments in the basin are extremely small, which is an important reason. In addition, during the fourth neotectonic movement, a flaming mountain was formed in the middle of the basin from east to west, and due to the blocking effect of this low mountain, the weathered material carried down by the flowing water from the Tianshan Mountains could only accumulate in the north of the mountain, and the south of the mountain was protected from accumulation, so that the terrain was kept below sea level for a long time.

The terrain of the Turpan Basin is special, surrounded by mountains, the main peak of the Bogda Mountain in the north reaches 5445 meters above sea level, and the elevation of the Ayding Lake in the basin is -154 meters, in such a short horizontal distance, the height difference is 5600 meters, which can be called a unique in nature.

The lowest basin in the world is the Turpan Basin, with the lowest elevation meters.

From the perspective of topographic units, the Turpan Basin can be regarded as the lowest basin in the world.
