China has great physical diversity. The eastern plain and southern coasts of the country consist of fertile lowlands and foothills. They are the location of most of China's agricultural output and human population. The southern areas of the country consist of hilly and mountainous terrain. The west and north of the country are dominated by sunken basins, rolling plateaus, and towering massifs. It contains part of the highest tableland on earth, the Tibetan Plateau, and has much lower agricultural potential and population.
The Tian Shan, also known as the Tengri Tagh or Tengir-Too, meaning the "Mountains of God/Heaven", is a large system of mountain ranges in Central Asia. The highest peak is at the Jengish Chokusu at 7,439 metres (24,406 ft) high. Its lowest point is at the Turpan Depression, which is 154 m (505 ft) below sea level.
Lop Nur or Lop Nor is a now largely dried-up salt lake formerly located in the eastern fringe of the Tarim Basin in the southeastern portion of the Xinjiang Autonomous Region, northwestern China, between the Taklamakan and Kumtag deserts. Administratively, the lake is in Lop Nur town, also known as Luozhong of Ruoqiang County, which in its turn is part of the Bayingolin Mongol Autonomous Prefecture.
The Tarim River, known in Sanskrit as the Śītā, is an endorheic river in Xinjiang, China. It is the principal river of the Tarim Basin, a desert region of Central Asia between the Tian Shan and Kunlun Mountains. The river historically terminated at Lop Nur, but today reaches no further than Taitema Lake before drying out.
The Tarim Basin is an endorheic basin in Xinjiang, Northwestern China occupying an area of about 888,000 km2 (343,000 sq mi) and one of the largest basins in Northwest China. Located in China's Xinjiang region, it is sometimes used synonymously to refer to the southern half of the province, that is, Southern Xinjiang or Nanjiang, as opposed to the northern half of the province known as Dzungaria or Beijiang. Its northern boundary is the Tian Shan mountain range and its southern boundary is the Kunlun Mountains on the edge of the Tibetan Plateau. The Taklamakan Desert dominates much of the basin. The historical Uyghur name for the Tarim Basin is Altishahr, which means 'six cities' in Uyghur. The region was also called Little Bukhara or Little Bukharia.
Dzungaria, also known as Northern Xinjiang or Beijiang, is a geographical subregion in Northwest China that corresponds to the northern half of Xinjiang. Bound by the Altai Mountains to the north and the Tian Shan mountain range to the south, Dzungaria covers approximately 777,000 km2 (300,000 sq mi), and borders Kazakhstan to the west and Mongolia to the east. In contexts prior to the mid-18th century Dzungar genocide, the term "Dzungaria" could cover a wider area, coterminous with the Oirat-led Dzungar Khanate.
The Yarkand River is a river in the Xinjiang Uyghur Autonomous Region of western China. It originates in the Siachen Muztagh in a part of the Karakoram range and flows into the Tarim River or Neinejoung River, with which it is sometimes identified. However, in modern times, the Yarkand river drains into the Midstream Reservoir and exhausts its supply without reaching the Tarim river. The Yarkand River is approximately 1,332.25 km (827.82 mi) in length, with an average discharge of 210 m3/s (7,400 cu ft/s).
Altyn-Tagh is a mountain range in Northwestern China that separates the Eastern Tarim Basin from the Tibetan Plateau. The western third is in Xinjiang while the eastern part forms the border between Qinghai to the south and Xinjiang and Gansu to the north.
The Yarkand deer, also known as the Tarim deer or Lop Nor stag, is a subspecies of the Central Asian red deer that is native to the province of Xinjiang, China. It is similar in ecology to the related Bactrian deer in occupying lowland riparian corridors surrounded by deserts. Both populations are isolated from one another by the Tian Shan Mountains and probably form a primordial subgroup of the Central Asian red deer.
The Eurasian Steppe, also called the Great Steppe or The Steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Hungary, Bulgaria, Romania, Moldova, Ukraine, southern Russia, Kazakhstan, Xinjiang, Mongolia and Manchuria, with one major exclave, the Pannonian steppe, located mostly in Hungary.
The Yarkand hare is a species of mammal in the family Leporidae. It has soft, straight, sandy brown dorsal pelage which has grayish-black stripes, and completely white ventral pelage. Endemic to China, the Yarkand hare is restricted to the Tarim Basin in Southern Xinjiang, China. It is mainly nocturnal, and forages on grass and crops. The female produces two or three litters annually, each consisting of two to five young. It is rated as near threatened on the International Union for Conservation of Nature Red List of Endangered Species and by the Red List of China's Vertebrates. However, Chinese geneticists have stated the species is "endangered" due to limited habitat and its fragmentation, and over-hunting and poaching.
The Keriya River is a river in the province of Xinjiang in China. It flows for 519 km (322 mi) from the Kunlun Shan mountain range north into the endorheic Tarim Basin, but is lost in the desert several hundred kilometers south of the Tarim River. The only major settlement along the river is Keriya Town, east of Hotan. The river is an important source of irrigation water and also supplies historically important oases along its course. Its drainage basin covers about 7,358 km2 (2,841 sq mi).
Tugay is a form of riparian forest or woodland associated with fluvial and floodplain areas in arid climates. These wetlands are subject to periodic inundation, and largely dependent on floods and groundwater rather than directly from rainfall. Tugay habitats occur in semi-arid and desert climates in Central Asia. Because Tugay habitat is usually linear, following the courses of rivers in arid landscapes, Tugay communities often function as wildlife corridors. They have disappeared or become fragmented over much of their former range.
Populus euphratica, commonly known as the Euphrates poplar, desert poplar, diversiform-leaved poplar, or poplar diversifolia, is a species of poplar tree in the willow family.
Altun Shan National Nature Reserve is a large, arid area in the southeast of Xinjiang Autonomous Region, on the northern edge of the Tibetan plateau and the southern edge of the Tarim Basin in northwest China. It surrounds the Kumkol Basin, an endorheic basin in the western third of the Altyn-Tagh mountains. The reserve is sometimes referred to as the "Arjin Mountains Nature Reserve", or "Aerjinshan". The reserve covers the southern portions of Qiemo County and Ruoqiang County of Bayingolin Mongol Autonomous Prefecture in Xinjiang.
Bayanbulak Grassland National Nature Reserve is the second largest grassland in China, located in the Bayanbulak Basin of the Tian Shan mountains in northwest China. The terrain is mostly flat, and encompasses a middle section of the Kaidu River. The reserve is 200 km northwest of Korla in Bayingolin Mongol Autonomous Prefecture of Xinjiang Uyghur Autonomous Region.
The Tian Shan montane steppe and meadows ecoregion covers a 2,000 km long stretch of grasslands of the isolated Tian Shan mountains of Central Asia. It is characterized by high-altitude flat and rolling grasslands.
The Tian Shan foothill arid steppe ecoregion covers the northern and western approaches to the Tian Shan mountains, centered on Lake Issyk-Kul in Kyrgyzstan. This region receives more moisture from Central Asia, thereby supporting more vegetation and diversity of plant and animal species than the deserts to the south.
The Central Asian riparian woodlands ecoregion is spread out across the deserts and plains of central Asia between the Aral Sea and the mountains 2,000 kilometres (1,200 mi) to the east. The long narrow components of the ecoregion follow the large rivers fed by snowmelt, and provide critical habitat for migratory birds as they travel through the arid region. The vegetation is referred to as tugai, characterized by low tangles of trees and brush along the edges of the rivers and associated wetlands, and fed by groundwater instead of precipitation.
