Dujiangyan Irrigation System
System is an ancient technological
wonder of China. More than 2,000 years
ago, Li Bing (c.250-200 BC) served
as a local governor of Shu State.
At that time, the Mingjiang River
flowed fast down from mountains. As
it ran across the Chengdu Plain, it
frequently flooded the Chengdu agricultural
area, and local farmers suffered much
from the water disaster. Li Bing and
his son designed this water control
system and organized thousands of
local people to construct the project.
The headwork is a large
hydraulic water project. It consists
of three main parts: the Fish Mouth
Water-Dividing Dam, the Flying Sand
Fence and the Bottle-Neck Channel.
When the construction
was completed, the dam system automatically
diverted the Minjiang River and channeled
it into irrigation canals. Gradually,
the Chengdu Plain turned into one
of the most fertile places in China.
Since 1949, expansion has been undertaken,
and at present, the system works very
effectively. It irrigates farming
land across 33 counties in West Sichuan
Province. The system benefits local
people, and the people are proud of
the Dujiangyan Irrigation system.
On the 29th of November
2000, Dujiangyan Irrigation System
and Mt. Qingcheng were placed on the
World Cultural Heritage list.
