In China today, 130.04 million ha of land are cultivated, mainly on the Northeast Plain, the North China Plain, the Middle-Lower Yangtze Plain, the Pearl River Delta and the Sichuan Basin. The fertile black soil of the Northeast Plain, the largest plain in China with an area of more than 350,000 sq km, abounds in wheat, corn, sorghum, soybeans, flax and sugarbeet. The deep, brown topsoil of the North China Plain is planted with wheat, corn, millet and cotton. The Middle-Lower Yangtze Plain's flat terrain and many lakes and rivers make it particularly suitable for paddy rice and freshwater fish, hence its designation of "land of fish and rice." This area also produces large quantities of tea and silkworms. The purplish soil of the warm and humid Sichuan Basin is green with crops in all four seasons, including paddy rice, rapeseed and sugarcane, making it known as the "land of plenty." The Pearl River Delta abounds with paddy rice, harvested 2-3 times every year.
Forests cover only 175 million ha of China. The Greater Hinggan, Lesser Hinggan and Changbai mountain ranges in the northeast are China's largest natural forest areas. Major tree species found here include conifers, such as Korean pine, larch and Olga Bay larch, and coniferous-broadleaf trees such as white birch, oak, willow, elm and Northeast China ash. Major tree species in the southwest include the dragon spruce, fir and Yunnan pine, as well as teak, red sandalwood, camphor, nanmu and padauk. Often called a
kingdom of plants," Xishuangbanna in the south of Yunnan Province is a rare tropical broadleaf forest area in China, playing host to more than 5,000 plant species.
Grasslands in China cover an area of 400 million ha, stretching more than 3,000 km from the northeast to the southwest. They are the centers of animal husbandry. The Inner Mongolian Prairie is China's largest natural pastureland, and home to the famous Sanhe horses, Sanhe cattle and Mongolian sheep. The important natural pasturelands north and south of the Tianshan Mountains in Xinjiang are ideal for stockbreeding. The famous Ili horses and Xinjiang fine-wool sheep are raised here.
China's cultivated lands, forests and grasslands are among the world's largest in terms of sheer area. But due to China's large population, the per-capita areas of cultivated land, forest and grassland are small, especially in the case of cultivated land -- only one third of the world's average.
China is rich in mineral resources, and all the world's known minerals can be found here. To date, geologists have confirmed reserves of 158 different minerals, putting China third in the world in terms of total reserves. Reserves of the major mineral resources, such as coal, iron, copper, aluminum, stibium, molybdenum, manganese, tin, lead, zinc and mercury, are in the world's front rank. China's basic coal reserves total 334.2 billion tons, mainly distributed in northeast China and north China, with Xinjiang Uygur Autonomous Region, Shanxi Province and the Inner Mongolia Autonomous Region heading the field. China's 21.24 billion tons of the basic iron ore reserve are mainly distributed in northeast, north and southwest China. The country also abounds in petroleum, natural gas, oil shale, phosphorus and sulfur. Petroleum reserves are mainly found in northwest, northeast and north China, as well as in the continental shelves of east China. The national reserves of rare earth metals far exceed the combined total for the rest of the world.
Plants and Animals
China is one of the countries with the greatest diversity of wildlife in the world. There are more than 6,266 species of vertebrates, 10 percent of the world's total. Among them 2,404 are terrestrials and 3,862 fishes. There are more than 100 wild animal species unique to China including such well-known rare animals as the giant panda, golden-haired monkey, South China tiger, brown-eared pheasant, red-crowned crane, red ibis, white-flag dolphin and Chinese alligator. The black-and-white giant panda weighs on average 135 kg and lives on tender bamboo leaves and bamboo shoots. Because it is extremely rare --just over 1,500 are left at present -- it has become the symbol of the world's protected wild animals. The red-crowned crane, that could be as tall as 1.2 m, is covered with white feathers, with a distinctive patch of exposed red skin crowning its head and is regarded as a symbol of longevity in East Asia. The white-flag dolphin is one of only two species of freshwater whales in the world. In 1980, a male white-flag dolphin was caught for the first time in the Yangtze River, which aroused great interest among dolphin researchers worldwide.
China is also one of the countries with the most abundant plant life in the world. There are more than 32,000 species of higher plants, and almost all the major plants that grow in the northern hemisphere's frigid, temperate and tropical zones are represented in China. In addition, there are more than 7,000 species of woody plants, including 2,800-odd tree species. The metasequoia, Chinese cypress, Cathay silver fir, China fir, golden larch, Taiwan fir, Fujian cypress, dove-tree, eucommia and camplotheca acuminata are found only in China. The metasequoia, a tall species of arbor, is considered to be one of the oldest and rarest plants in the world. The golden larch, one of only five species of rare garden trees in the world, grows in the mountainous areas in the Yangtze River valley. Its coin-shaped leaves on short branches are green in spring and summer, turning yellow in autumn. China is home to more than 2,000 species of edible plants and over 3,000 species of medicinal plants. Ginseng from the Changbai Mountains, safflowers from Tibet, Chinese wolfberry from Ningxia and notoginseng from Yunnan and Guizhou are particularly well-known Chinese herbal medicines. China has a wide variety of flowering plants; the peony, a flower indigenous to China and known as the "king of flowers" is characterized by large blossoms, multiple petals and bright colors, and is treasured as one of the country's national flowers.
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.
