From 53 34' north latitude to 3565 438+0' north latitude, from north to south, from cold temperate zone to equatorial belt, it spans about 50 latitudes. About 70% of them are temperate (accounting for 25.9%), warm temperate (accounting for 18.5%) and subtropical (accounting for about 26%), and the heat conditions are superior.
From 73 east longitude to 135 05', the east-west span is nearly 62 longitudes, from the Pacific coast to the center of Eurasia, including humid (accounting for 32.2%), semi-humid (accounting for 17.8%), semi-arid (accounting for 19.2%) and arid (352.2%).
Extended data:
The territorial sea consists of the Bohai Sea (inland sea), the Yellow Sea, the East China Sea and the South China Sea, and the coastline of the eastern and southern continents is1.8000 km long.
China has a land border of 22,800 kilometers, bordering North Korea in the east, Mongolia in the north, Russia in the northeast and Kazakhstan, Kyrgyzstan and Tajikistan in the northwest.
The west and southwest border Afghanistan, Pakistan, India, Nepal, Bhutan and other countries, and the south borders Myanmar, Laos and Vietnam. The east and southeast are across the sea from Korea, Japan, the Philippines, Brunei, Malaysia and Indonesia.
The terrain of China is high in the west and low in the east, which is complex and diverse. The proportion of various landforms in the national land area is: mountain 33. 3%, plateau 26%, basin 65,438+08.8%, plain 65,438+02%, hilly 9. 9%.
The terrain forms three steps from west to east: the Qinghai-Tibet Plateau, the highest in the west of the world, has the highest terrain, with an altitude of more than 4,000 meters. It is composed of extremely high mountains and plateau surfaces and is known as the "roof of the world". It is the first step, bounded by Kunlun Mountain, Qilian Mountain and Hengduan Mountain, and the second step.
The Qinghai-Tibet Plateau is the second step between Daxing 'anling, Taihang Mountain, Wushan Mountain and Xuefeng Mountain in the east, with an altitude of1000-2000m, which is mainly composed of mountains, plateaus and basins. The vast plains and hills in eastern China are the third step. This landscape pattern was laid by the Mesozoic Yanshan movement.
