Dongting Lake
Dongting Lake or Lake Dongting (also Dong Lake, 洞庭湖; Pinyin: Dòngtíng hú; Wade-Giles: Tung-t'ing Hu) is a large, shallow lake in northeastern Hunan Province of China. It is a flood-basin of the Yangtze River (Chang Jiang); hence the lake's size depends on the season. The provinces of Hubei and Hunan are named after their location relative to the lake: Hubei means "North of the Lake" and Hunan means "South of the Lake" in Chinese.
Geography
In the July-September period, flood water from the Yangtze flows into the lake, enlarging it greatly. The lake's area, which normally is 2,820 km², may increase to 20,000 km² in flood season, when vast amounts of water and sediment from the Chang Jiang flow into the lake. The lake is also fed by four rivers: the Xiang, Zi, Yuan (沅) and Li rivers. In addition, the Xiao River (瀟) flows into the Xiang near Changsha, before the Xiang flows into the lake. Ocean-going vessels can travel through the Xiang to reach Changsha.
History
During the Han Dynasty, Yunmeng Marsh (雲夢大澤; yun2 meng4 da4 ze2), which lies to the north of Dongting Lake in Hubei Province, served as the main flood-basin of the Yangtze. The rich sediment of the marsh attracted farmers. Embankments were built, keeping the river out, and the Dongting Lake area south of the Yangtze gradually became the river's main flood-basin.
At that time, Dongting Lake was China's largest lake. Because of its size, it gained the name Eight-hundred-li-Dongting (八百里洞庭). Nowadays, it is the second-largest, after Poyang Lake (鄱陽湖), as much of the lake has been turned into farmland.
Culture and mythology
The area is well-known in Chinese history and literature. Dragon boat racing is said to have begun on the eastern shores of Dongting Lake as a search for the body of Qu Yuan (屈原), the Chu poet (340-278 BC), and a dragon-king is said to live at the bottom of the lake.
Junshan (君山), which was formerly a Daoist retreat, is a famous one-kilometer island with 72 peaks in the middle of the lake. The island is famous for Junshan Yinzhen tea, too. The basin of Dongting Lake and its surrounding area is famous for its scenic beauty, which has been encapsulated in the phrase 瀟湘湖南 (xiao1 xiang1 hu2 nan2; "Hunan of the Xiao and Xiang rivers").
The scenery of the Jiuyi Mountains (九嶷山) and of the Xiao and Xiang rivers below is often mentioned in Chinese poetry. During the Song Dynasty, it became the fashion to paint this region's scenery in a set of eight scenes, usually entitled as Eight Views of the Xiao and Xiang. The fashion spread to Japan, where eventually other famous places were substituted for the Xiao and Xiang rivers.
Environmental issues
In 2007 fears were expressed that China's finless porpoise, a native of the lake, might follow the baiji, the Yangtze river dolphin, into extinction.
There have been calls for action to save the finless porpoise, of which there are about 1400 left living, with between 700 and 900 in the Yangtze, with about another 500 in Poyang and Dongting Lakes.
2007 population levels are less than half the 1997 levels, and the population is dropping at a rate of 7.3 per cent per year.
Pressure on the finless porpoise population on Poyang Lake comes from the high numbers of ships passing through and sand dredging. [1]
