China Best Travel of Beautiful Jiuzhaigou

Came to Sichuan, to the Jiuzhaigou Huanglong, Leshan to Emei, Dujiangyan, and left with a Qingchengshan. Sichuan, a friend said to me, from the weir was built since 256 BC, Dujiangyan has been for us the benefit of 2200 years, and now continues to irrigate the Chengdu Plain of more than a thousand acres of farmland. Human conquest of nature, exploitation of natural engineering, both from the size and skill, which can not match and Dujiangyan. Therefore, we must look to Dujiangyan.

In order to ensure the departure time, the tour guide took us wake up early in the morning, 7 o'clock from Chengdu to Dujiangyan, the. Is under the jurisdiction of Chengdu Dujiangyan, located some 55 km Chengdu, Xi Bei is a prefecture-level city. Sichuan had "Quiet difficult, extremely difficult," said, now is not the same, the highway has to Chengdu and Dujiangyan two cities together.
Attack and had heard the story of Li Bing, father and son built the Dujiangyan, in the very hour trip has been to Dujiangyan, but no impression, so how was built the weir, basically can not tell how to share a stream.

Car to Dujiangyan (tickets 90 yuan / person), all the way to follow guide, carefully listening to tour guides explain. Advanced the Second Temple, and later to the famous Alan rope bridge. Alan had not the ancient rope bridge rope bridge, replaced with modern technology to build a new bridge, from a distance was a magnificent sight. Bridge is about 200 meters (own estimates, may not be allowed), go on the bridge, threw, scary. Standing on the bridge center, overlooking the Dujiangyan Irrigation Project 2,300 years of history, the hearts of spontaneously emerged in one word: great. Dujiangyan, the tour guide gave a detailed drainage principles and control methods, just as "great" a word I can never express the emotional heart of Dujiangyan. It works great, the design of compact, or so I was shocked. Dujiangyan project operating mechanism, not a diversion dam in the river diversion works, but Jiang Zhongshun water weir, the river banks of the terrain and the use of principles of automatic control of fluid volume of water, the flood and sediment. In addition to extensive water network project canals, the main watershed from the headworks of the fish head embankment, spillway weir windblown sand and treasure bottle has three major components. Whether Qinggemanwu Minjiang water, or pour raging through the treasure bottle she melodious to divert to the Chengdu Plain, irrigation ten thousand ares fertile, windblown sand and gravel through the weir escape.
