Chinese scientists embarked on an expedition on July 20 to investigate the water resources and ecological environment in the headwater regions of the Yangtze and Lancang rivers.
The expedition will carry out scientific investigations into river hydrology, water ecology, soil erosion, glaciers and permafrost in Qinghai.
Qinghai is home to the Sanjiangyuan area, which contains the headwaters of China's three major rivers: the Yangtze River, the longest in China; the Yellow River, the second-longest; and the Lancang River, which is known as the Mekong River after it flows out of China.
As important parts of the Qinghai-Xizang Plateau ecosystem, the headwater regions of the Yangtze and Lancang rivers play a crucial role in safeguarding water resources, protecting biodiversity and ensuring ecological stability.
