Historical evolution

In the 1970s and 1980s, in order to change the appearance of "nine droughts in ten years" around Luoding City, Luoding organized more than 10000 people to build changgangpo aqueduct in more than four years.

In 1973, Guo Rongchang, then Secretary of the county Party committee (later Secretary of the Guangdong provincial Party committee), asked the County Water Conservancy Bureau to immediately carry out preparatory work. However, the rainfall collection area of the whole reservoir area is only 18 square kilometers, which is far from meeting the water storage requirements of medium-sized reservoirs.

In November 1976, the construction of changgangpo aqueduct started.

On June 27, 1979, during the construction of No.14 span of changgangpo aqueduct with a span of 51 meters, the steel frame and arch beam suddenly crashed, causing one person to die on the spot and three people to be seriously injured; on October 31, 1979, the section in charge of Xiadong No.4 group at the exit of aqueduct collapsed, 6 people were killed and 5 people were injured.

In January 1981, the changgangpo aqueduct was completed, and the total cost was only 5.3 million yuan

"New clothes on Luoding mountains and rivers" about Luoding water conservancy construction was also compiled into the primary school textbook in the 1970s.

In October 2012, when CCTV's "village pact" program team went to Luoding to produce "village pact · Luoding, Guangdong", they wanted to find a place that not only represents Luoding, but also has beautiful scenery for the program.

"

Changgangpo aqueduct can be called the world's top. It is one of the great projects in the history of water conservancy in China. This project has created a miracle in the history of man-made water conservancy. After the completion of changgangpo aqueduct project, it has played a significant engineering benefit. The changgangpo aqueduct, with a huge dragon like body, led the upstream Longjiang River and Taiping River into the jinyinhe reservoir, moistening more than 200000 mu of farmland in the downstream. Since then, Luoding basin has become a "land of abundance" with drought, flood and income. Therefore, Luoding has successively won the title of "national advanced county of grain production"
