Addressing a recent forum1 on the Yangtze River held in Changsha, the capital of Central China's Hunan Province, Zhu Lieke, deputy head of the State Forestry2 Administration, said China has made an inventory3 of 173 wetlands, most of which are in northeast China and the Yangtze River Valley.
Thirty of the country's wetlands are listed in the international wetland catalogue, and one third of them are situated4 along the Yangtze.
"Phenomena5 such as the rapid drop in the number of lakes and fast shrinkage in lake area got worse as China's economy tears through resources," said Zhu, who warned that wetlands in the Yangtze River Valley face unprecedented6 ecological7 threats.
"The problems that plague wetlands in the Yangtze River Valley include pollution, ecological degradation8 and dwindling9 water resources," said Zhu. "The protection of our wetlands is urgent."
The 6,300-km-long Yangtze, the country's longest, originates in the Tanggula Range on the Qinghai-Tibet Plateau and passes through Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai before emptying into the East China Sea.
Wetlands in the Yangtze River Valley include salty plateau lakes and plateau marshlands, the galaxy10 of lakes on the middle reaches of the Yangtze, and the coastal11 wetland near Chongming Island at the estuary12 of the river.
Dongting Lake, which flows into the Yangtze River and also serves as an important wetland, for instance, is shockingly polluted. Marine13 life has been decimated and people are catching14 a disease called schistosomiasis -- caught by swimming or wading15 in water where there are parasitic16 worms.
The water area of Dongting Lake has shrunk from 4,350 sq km in 1949 to present 2,625 sq km as a result of silting17 and land reclamation18 for farming.
According to Zhu, the country has already launched three programs to protect the wetlands in the Yangtze River Valley, including the national program for conservation of wildlife, plants and nature reserves, and the program to protect the Sanjiangyuan wetland in Qinghai Province. But much remains19 to be done.
