Dujiangyan Irrigation System

Familiar with the technical content of Dujiangyan, you can go and see, otherwise you can't understand it. It is recommended to walk to Yulei Mountain and overlook Dujiangyan from a high floor to see the panoramic view.

Dujiangyan is really worth a visit. Only the scenery may not feel beautiful enough and look unremarkable, but the wisdom of the ancestors in it is really impressive. The top priority is to understand the history and ask for a good explanation. Otherwise, it is the same as coming and never coming.

The scenery alone is not very special, mainly to see the humanities. The scenic spot is very large, there are sightseeing cars, the site seems to be not many, and it is expensive. There is a place to climb the ladder, not especially suitable for the elderly or too small children. The South Bridge is outside the scenic spot and there is no ticket.

The last time I went to Dujiangyan Scenic Area for 33 years, the scenery is still the same, but the tickets have risen a lot, and there are many tourists. At the highest point, Yulei Pavilion was installed with an escalator (20 one way).

It is beautiful and worth a visit to Dujiangyan. It is an ancient and important water conservancy project, which not only played an important role in history, but also still has irreplaceable value in modern society. ① 2 Dujiangyan is located in Dujiangyan City, Chengdu City, Sichuan Province, and is Taishou Li Bing, Qin Guoyu County. It was built in 256 BC. The project is mainly composed of fish mouth, flying sand scorpion. And Baopingkou. Composition, through the cooperation of these three parts, the automatic adjustment of water volume, sand discharge and other functions. The construction of Dujiangyan not only solved the local water problem, but also provided stable water source for agricultural production and promoted the economic development of Sichuan. The engineering design and construction of Dujiangyan reflects the wisdom and creativity of the ancients. It is not only a water conservancy project, but also has a rich cultural connotation, and its cultural significance penetrates into many aspects such as diet, architecture, dialect and national culture.

Dujiangyan is a county seat in Chengdu. There are major water conservancy projects of world heritage in Dujiangyan Scenic Area. The scenic area is very large and the scenery is very spectacular. It is worth coming to see. While watching and learning, Yujun County Shou Li Bing, in the sight of Yulei Mountain to block the water upstream, Yulei Mountain on both sides of the water often flooded and the downstream drought, so he thought of the way of "fire watering", it took eight years to chiseled Yulei Mountain into the current "bottle mouth"; At the same time, the "fish mouth" position in the upper reaches of the four or six shunts, and the two-eighth sand, divided the Lijiang River into two sides of the outer river, the inner river, the outer river flood, the inner river irrigation; In the "flying sand" position, that is, a short dam is built on the periphery of the inner river, further dumps the mud and sand in the inner river, and regularly cleans up to avoid sediment silt. When the water volume of the inner river is too large, the excess water can be discharged into the outer river to avoid floods through the overflow channel of the flying sand. Such water conservancy projects without dam drainage, withstand the test of time to benefit the people, come here to feel the wisdom of the ancients and the greatness of the project. I watched the performance of Dujiangyan on the Fish Mouth near the "Fish Mouth". There was also a small episode. There was a fan dance. A little brother threw the fan out. Oh, I was so panicked. Then he and the same stage were trying to laugh and continue to do the action. I was also laughing hahaha. It's almost over that a little sister's fan is broken, so helpless, but still insist on throwing hahaha. The whole performance experience is very good. I want to give a thumbs up to the little brothers and sisters of each performance. It is a wonderful performance. You are awesome!

The water conservancy project 2279 years ago is still benefiting the generations of children and grandchildren. How can it not be touched! The entire scenic spot includes Qin Yulou, Erwang Temple, Yuzui, Baopingkou, Blue Eyes and other modules. Each has a culture, history, and a point of view. If you want to watch it slowly, a day is not enough.

The amazing great water conservancy project, composed of the three major parts of the flying sand spillway, the bottle mouth water inlet and the affiliated projects such as Baizhangdi and the human character dike, scientifically solved the automatic diversion of river water (four or six points of water in the fish mouth dike), automatic sand discharge (two or eight points of sand in the fish mouth dike), Control of water intake (bottle mouth and flying sand), breathtaking
