Lakes Near the Taklamakan Desert, China

China - September 24th, 2009

Several lakes are visible in this image of western China, despite being near to the arid Taklamakan Desert. Of note on the eastern end of the desert is the dry basin of the former Lake Lop Nur, now containing an area of salt fields that appear as a light yet bright blue rectangle.

Visible just north of the Taklamakan desert is Lake Bosten, a dark blue freshwater lake located 57 km northeast of Korla, Xinjiang in the Bayin’gholin Mongol Autonomous Prefecture. With an area of about 1,000 square kilometers, it is the largest lake in Xinjiang.

Further north, appearing greenish in color, is Lake Ulungur, in Fuhai, Xinjiang. Covering an area of 1,035 square kilometers, the lake is one of China’s ten largest freshwater lakes. Lake Ulungur is divided into two sections: Buluntuo Lake and the smaller Jili Lake.

Finally, the lower end of Lake Zaysan, a freshwater lake in eastern Kazakhstan, can be seen in the upper left corner. The ca. 1,810 km² (700 mi²) lake is located in a hollow between the Altai and Tarbagatai Mountains.

Freshwater Lake Ulungur is located in Fuhai, Xinjiang, China. Its total surface area is 1,035 square kilometers, although it is divided into two sections: the larger Buluntuo Lake and the smaller Jili Lake.

The lake is fed by the Ulungur River. Further water is diverted into it by a canal built through the watershed between the Ulungur and Irtysh rivers.

North of the lake arise the snow-capped Altai Mountains, the source of the Irtysh and Ob Rivers. The mountain range runs through central Asia, where Russia, China, Mongolia and Kazakhstan come together. As they extend southeast, the peaks gradually become lower and merge into the high plateau of the Gobi Desert.

Dzungaria is a geographical region in northwest China corresponding to the northern half of Xinjiang. It covers approximately 777,000 km2 (300,000 sq mi), lying mostly within Xinjiang, and extending into western Mongolia and eastern Kazakhstan.

The core of Dzungaria is the triangular Dzungarian Basin (also Junggar Basin) with its central Gurbantunggut Desert. It is bounded by the Tien Shan to the south, the Altai Mountains to the northeast and the Tarbagatai Mountains to the northwest.

The Dzungarian Basin is largely steppe and semi-desert; only a gap in the mountains to the north allows moist air masses to provide the basin lands with enough moisture to remain semi-desert rather than becoming a true desert. This also allows a thin layer of vegetation to grow. Here, thanks to additional irrigation, green fields cover some of the land, particularly to the south, contrasting with the sand dunes to the east.

Runoff from the surrounding mountains into the basin supplies several lakes, including the long, shallow Mana Sihu towards the center of the image.

Rectangular fields cover the land east of Lake Ulungur, in Fuhai, Xinjiang, China. With an area of 1,035 square kilometers, the lake is one of China’s ten largest freshwater lakes.

Lake Ulungur is divided into two sections: Buluntuo Lake and the smaller Jili Lake and is fed by the Ulungur River. In 1969, a canal was built through the watershed between the Ulungur and the Irtysh River in order to divert water into the lake.

Qiemo River, Between Dunes and Mountains

The Qiemo River, also called the Cherchen or Qarqan River, runs across the Tarim Basin in this orthorectified image of part of the Xinjiang Uyghur Autonomous Region.

After flowing down from the Altun Shan Range of the Kunlun Mountains, the river runs through Qiemo County, then turns eastward, flanking the southern edge of the Taklamakan Desert, and eventually feeds into the Lop Nor salt marshes. Some dunes of the Taklamakan are visible near the river.
