Human beings are catching up with water and living
Cities stand by water
This is the obsession of mankind for thousands of years
It is also the law for thousands of years

How big is the reservoir area?
The water area is about 1050 square kilometers
is equivalent to the area of Hong Kong
is almost the same as the water area of Three Gorges Reservoir Area
and the dragon body is the main channel

The people of Xichuan have experienced seven immigrations from all over the world

The mid-line project started
Construction difficulty began to appear from the source
Although the Danjiangkou Dam was only increased by 14.6 meters
that is, the height of five floors
, the water pressure will increase by 40%
. New dams are built on the old dam that has been in service for nearly 40 years
The difficulty is no less than or even more than the newly built dam.
. Workers cut out keyways and implanted steel bars.
. At the peak of construction, 3,000 people fought on the front line.
. The feat was finally completed after nearly 8 years. The first of the South-to-North Water Diversion Center Project Channel in Xichuan County, Nanyang City was photographed by the drone (data picture). Xinhua News Agency reporter Feng Dapeng photographed

has brought the water quality of Danjiangkou Reservoir to 95% reach Class I water
In order to build an "ecological barrier" for water diversion and care for the delivery of clear water in one reservoir, Xichuan County actively innovates the afforestation mechanism, and signs afforestation contract with enterprises and large afforestation households in a market-oriented operation method, and repays funds at the survival rate, greatly improving the survival rate of afforestation. According to statistics, the county's annual ecological forestry and afforestation greening area is promoted at a rate of 100,000 mu, with a survival rate of more than 90%. The qualified afforestation area ranks first in the county level in Henan Province for 10 consecutive years. Zhu Peixian and Yang Zhenhui photographed

bid farewell to high fluorine water and bitter salty water

It can be said that
South-to-North Water Diversion has alleviated the water shortage to a certain extent
However, the distribution of water resources is uneven
The phenomenon of north-to-north water shortage will still exist for a long time
Drops of south-to-north water is hard to come by
