Different areas in Korla have different altitudes. For example, South Jianguo Road in Korla City is 934 meters above sea level. The height is calculated with Qingdao Yellow Sea as the zero point.

Extended data:

First, the sea level in different sea areas is different. For example, the sea level on the Pacific side of the Panama Canal is 20 centimeters higher than that on the Atlantic side.

Chinese mainland: The elevation adopts the mean sea level of the Yellow Sea calculated from the long-term observation data of Qingdao Port Tide Station as the datum (zero elevation plane).

Taiwan Province Province: Take the "horizontal origin of Taiwan Province Province" on the east coast of Keelung Port as the measurement benchmark.

Japan: Based on the average sea level in Tokyo Bay, the measured datum point is located at the "Japanese horizontal origin" of the Land Survey Department of the former General Staff Department/the vestibule of the National Assembly in Chiyoda District, Tokyo.

UK: May 19 15 to April 19265438, average sea level in Newlin, Cornwall, UK.

Netherlands: The average sea surface of Amsterdam is "Normaal Amsterdams Peil".

Second, the geographical environment

location

Korla is located in the middle of Xinjiang Uygur Autonomous Region, with the east longitude of 8514 ′10 ″-86 34 ′ 21″ and the north latitude of 46 5438+010 ′ 48 ″-42 2/kloc-. The administrative area of the city is 7268 square kilometers, with the east-west length of 127 kilometers and the north-south width of 105 kilometers.

Korla is located in central Xinjiang, the center of Eurasia and Xinjiang, and the transportation hub of southern Xinjiang. National highways 2 18 and 3 14 cross the whole territory, and the southern Xinjiang railway passes through the territory, with civil aviation flights connecting Urumqi.

On the northeast edge of Tarim Basin, there are Kuruk Mountain and Hora Mountain, branches of Tianshan Mountains, in the north, and Taklimakan Desert, the second largest desert in the world, in the south. The southern and western parts of Korla Oasis Plain are connected with Tarim Basin, forming a vast fan-shaped oasis.

The tiemenguan Canyon, which starts from Mount Hora in the north and ends at Mount Kuruk in the east, is 14km long and has been the gateway to southern Xinjiang, Qinghai, Pamirs and South Asia since ancient times.

climate

Because there are Mount Hora in the north and Mount Kuruk in the east, the influence of cold air in the north and wet air in Yanqi Basin on Korla City is obviously weakened.

Tiemenguan has become the natural dividing line between northern and southern Xinjiang. Korla has a warm and humid climate in Eurasia and is rich in light and heat resources. In ancient times, Korla was one of the earliest reclamation areas in the western regions.

Korla has a warm temperate continental arid climate, with a total sunshine of 2990 hours, an average frost-free period of 2 10 days, an annual average temperature of1.4℃, a minimum of -28℃, an annual average precipitation of 58.6 mm and an annual maximum evaporation of 2788.2 mm, mainly in the northeast wind.

Korla has a mild climate and fertile soil. The Peacock River, the mother river of Korla, runs through the city, reaching 27 1km, with an average annual runoff of1.1.80 billion cubic meters.
