Land area
With a landmass of 9,600,000 sq km, China is the third largest country in the world.
Located in the east of the Asian continent, on the western shore of the Pacific Ocean, the People's Republic of China has a land area of about 9.6 million sq km, and is the third-largest country in the world, next only to Russia and Canada.
From north to south, the territory of China stretches from the center of the Heilong River north of the town of Mohe to the Zengmu Reef at the southernmost tip of the Nansha Islands, covering a distance of 5,500 km. From east to west, the nation extends from the confluence of the Heilong and Wusuli rivers to the Pamirs, covering a distance of 5,200 km.
With a land boundary of some 22,800 km, China is bordered by Korea to the east; Mongolia to the north; Russia to the northeast; Kazakhstan, Kyrgyzstan and Tajikistan to the northwest; Afghanistan, Pakistan, India, Nepal and Bhutan to the west and southwest; and Myanmar, Laos and Vietnam to the south. Across the seas to the east and southeast are the Republic of Korea, Japan, the Philippines, Brunei, Malaysia and Indonesia.
China's mainland coastline measures approximately 18,000 km, with a flat topography, and many excellent docks and harbors, most of which are ice-free all year round. The Chinese mainland is flanked to the east and south by the Bohai, Yellow, East China and South China seas, with a total maritime area of 4.73 million sq km. The Bohai Sea is China's continental sea, while the Yellow, East China and South China seas are marginal seas of the Pacific Ocean.
A total of 5,400 islands dot China's territorial waters. The largest of these, with an area of about 36,000 sq km, is Taiwan, followed by Hainan with an area of 34,000 sq km. The Diaoyu and Chiwei islands, located to the northeast of Taiwan Island, are China's easternmost islands. The many islands, islets, reefs and shoals in the South China Sea, known collectively as the South China Sea Islands, are China's southernmost island group. They are called the Dongsha (East Sandbar), Xisha (West Sandbar), Zhongsha (Middle Sandbar) and Nansha (South Sandbar) island groups according to their geographical locations.
Physical features
China's topography was formed around the emergence of the Qinghai-Tibet Plateau, the most important geological event over the past several million years. Taking a bird's-eye view of China, the terrain gradually descends from west to east like a staircase. Due to the collision of the Indian and Eurasian plates, the Qinghai-Tibet Plateau rose continuously to become the top of the four-step "staircase," averaging more than 4,000 m above sea level, and called "the roof of the world." Soaring 8,848 m above sea level on the plateau is Mount Qomolangma (Mount Everest), the world's highest peak and the main peak of the Himalayas. The second step includes the gently sloping Inner Mongolia Plateau, the Loess Plateau, the Yunnan-Guizhou Plateau, the Tarim Basin, the Junggar Basin and the Sichuan Basin, with an average elevation of between 1,000 m and 2,000 m. The third step, dropping to 500-1,000 m in elevation, begins at a line drawn around the Greater Hinggan, Taihang, Wushan and Xuefeng mountain ranges and extends eastward to the coast of the Pacific Ocean. Here, from north to south, are the Northeast Plain, the North China Plain and the Middle-Lower Yangtze Plain. Interspersed amongst the plains are hills and foothills. To the east, the land extends out into the ocean, in a continental shelf, the fourth step of the staircase. The water here is mostly less than 200 m deep.
Rivers and lakes
China abounds in rivers. More than 1,500 rivers each drain 1,000 sq km or larger areas. Most of the large rivers have their source on the Qinghai-Tibet Plateau, and drop greatly between source and mouth. As a result, China is rich in water-power resources, leading the world in hydropower potential, with reserves of 680 million kw.
China's rivers can be categorized as exterior and interior systems. The catchment area of the exterior rivers that empty into the oceans accounts for 64 percent of the country's total land area. The Yangtze, Yellow, Heilong, Pearl, Liaohe, Haihe and Huaihe rivers flow east, and empty into the Pacific Ocean. The Yarlungzangbo River in Tibet, which flows first east and then south into the Indian Ocean, boasts the Yarlungzangbo Grand Canyon, the largest canyon in the world, 504.6 km long and 6,009 m deep. The Ertix River flows north from the Xinjiang Uygur Autonomous Region to the Arctic Ocean. The catchment area of the interior rivers that flow into inland lakes or disappear into deserts or salt marshes makes up about 36 percent of China's total land area. Its 2,179 km make the Tarim River in southern Xinjiang China's longest interior river.
The Yangtze, 6,300 km long, is the largest river in China, and the third largest in the world, next only to the Nile in Africa and the Amazon in South America. Passing through high mountains and deep valleys, the upper section of the Yangtze River is abundant in water resources. Known as the "golden waterway," the Yangtze is a transportation artery linking west and east, its navigation benefiting from excellent natural channels. The middle and lower Yangtze River areas have a warm and humid climate, plentiful rainfall and fertile soil, making them important agricultural regions. The Yellow River is the second largest river in China with a length of 5,464 km. The Yellow River valley was one of the birthplaces of ancient Chinese civilization. It has lush pasturelands along its banks, flourishing agriculture and abundant mineral deposits. The Heilong River is a large river in north China with a total length of 4,350 km, of which, 3,101 km are in China. The Pearl River (Zhujiang), 2,214 km long, is a large river in south China. In addition to those bestowed by nature, China has a famous man-made river - the Grand Canal, running from Beijing in the north to Hangzhou in Zhejiang Province in the south. Work first began on the Grand Canal as early as in the fifth century A.D. It links five major rivers: the Haihe, Yellow, Huaihe, Yangtze and Qiantang. With a total length of 1,801 km, the Grand Canal is the longest as well as the oldest man-made waterway in the world.
China's territory includes numerous lakes, most of which are found on the Middle-Lower Yangtze Plain and the Qinghai-Tibet Plateau. Freshwater lakes such as Poyang, Dongting, Taihu, and Hongze mostly lie in the former area, while in the latter are saltwater lakes, such as Qinghai, Nam Co and Siling Co. Poyang Lake, in the north of Jiangxi Province and with an area of 3,583 sq km, is the largest of its kind. Qinghai Lake, in northeast Qinghai Province and with an area of 4,583 sq km, is the largest one of its kind.
