BEIJING -- China Tuesday began to implement an 
ordinance to regulate and control the water volume of the Yellow River, the 
second longest river in the country. 
This is China's first law on water volume control of the 
long rivers, said Li Guoying, head of the Yellow River Conservancy Committee 
under the Ministry of Water Resources.

At a press conference of the Information Office of the State Council, Li said 
the regulation is aimed to strengthen management of the water resources of the 
Yellow River, realize sustainable utilization of the water resources, improve 
the ecological environment along the river, and promote the economic and social 
development of valley areas of the river. 
The ordinance stipulates that the water volume of the Yellow River will be 
under the unified control of the State. It also has specific stipulations on the 
water allocation, regulation and control, emergency management, supervision and 
legal responsibilities. 
The Yellow River, popularly known as China's Mother river, is the major water 
resources for the northwest and northern China. The Yellow River plays a vital 
role in China as it provides water for 12 percent of China's 1.3 billion people, 
15 percent of China's farmland and more than 50 large and medium-sized cities. 
However, the water level of the river changes remarkably in different years 
and the river suffers a great imbalance of the water flow in different seasons 
and regions. 
The Yellow River carries more silt than any other river in the world. It was 
well known as a disastrous river as floods deprived of numerous lives in the 
past 2,000 years. 
The water volume in the river has been shrinking over the past years due to 
climate changes and degradation of the environment. Some parts of the river were 
dry for 21 times during the period from 1971 to 1999. 
The source water of the Yellow River has dwindled by 23 percent more in the 
past ten years than the average level in the previous 40 years in northwest 
China's Qinghai Province, environmental officials said. 
Li said China has taken measures to protect water sources and control the 
total volume used by cities along the Yellow River, which prevented the river 
from drying up over the past seven years. 
The successful experience lays a solid foundation for the making of the 
ordinance, Li added.
