Rain Dujiangyan - Sichuan, China Youth Travel Service

Came to Sichuan, although there are a lot of beautiful scenery, but most want to see is the Dujiangyan. Sichuan Province, said a friend gave me, from the weir, built since 256 BC, Dujiangyan has been for us the benefit of 2200 years, and now continues to irrigate the Chengdu Plain of the more than 1000 mu of farmland. The human conquest of nature, the development of natural engineering, both in scale and skill, no one can match, and Dujiangyan. Busy working for the public service the next morning, we will proceed by car to Dujiangyan. Dujiangyan is the jurisdiction of Chengdu, is located about 55 km northwest of Chengdu, is a prefecture-level cities. Sichuan has been called "difficult roads of Shu extremely difficult for" remark, and now not the same, and highways have already Chengdu and Dujiangyan two cities together. Perhaps the Dujiangyan pouring rain itself is a book, need to move with solemn mood carefully read, out of Chengdu, the sky Xili it began to rain, the scenery along the way to many are being shrouded in misty rain, the hinterland has Shuzhong Some stories have cast a veil of mystery is like a mystery. Attack and heard that Li Bing, the story of his son built the Dujiangyan are known to be a great thing, but how was weir built, how share of flow, detailed little things it can not come. A long history, the distance involved, even more fascinated with it being speculation. I remember in 1995 to Belgium, in the hot sun city, see the Meuse River, built a dam, the dam has raised the river, the river away from the left side of the river drainage. Accompanied by hearing people say, where Meuse River was diverted, and downstream to the river is called the Maas River, which leads to the river added to the A and Bate canal, through Antwerp to the sea. The water conservancy project on the local shipping and agricultural irrigation has played a tremendous role. I also recall that in the front of the dam, in an above the surface on the stage, stands with a statue of a figure tall and straight, the wind flowing people, facing the river Meuse, to the upper reaches of the outlook. I guess, this figure must be the designers of water conservancy projects. At that time, I think of Dujiangyan, and this, like water projects, are part of the human to use their own wisdom, a gift of nature to be full advantage of results. I think the construction of Dujiangyan than a certain age it is early, it is more ambitious than the bar. Car to Dujiangyan, the rain is still under the boundless light rain up and down along the Minjiang River into hiding. Dujiangyan can not watch the scenery along the river, had no choice but carries a bit suspect, along the dense forest of trees, watching Fulong view inside the graphic description. Although there is sufficient imagination, but when details about the Dujiangyan drainage principles and control methods, and that ambitious project, design sophistication, or so I was shocked. Dujiangyan project running mechanism, not a diversion dam in the river diversion works, but in the river weir downstream to the use of river banks of the terrain and the amount of fluid mechanics principles of automatic control water, flood discharge and sediment-flushing of the. In addition to the huge water network project canals, the main watershed fish head from the headworks of the embankment, spillway weir windblown sand and Po bottle has three major components. Fish head watershed function is Congjiang Tsutsumi carve out part of the river to the Neijiang, in the river from the heap, where more than 20 meters to open a port ---- Po bottle of water, the introduction of river water into the water network, back to the rest of the river is still into the Minjiang River, while the water flow is by windblown sand to control the level of weir. When the floods, due to river bend, water bottle by the centrifugal role of Po the impact of slow, automatic control of water. Thus, the structure and principles of Dujiangyan, and the sun city water engineering structures and principles that are fundamentally different. Compared to the sun that works, whether it is the principle and construction of Dujiangyan difficulty, I wonder how many times higher. Minjiang fast-flowing, silt content was high, coupled with the complex geological conditions, traffic large dams may lead to disastrous results. Even the building of the dam, at that time can not solve the regulation of water flow and sediment deposition problems. Dujiangyan's subtlety lies in the fact the whole project using the principles of flow mechanics, and build a diversion weir in the river bend place, dug Aquarius Hukou, with the level of the river and flow Jihuan automatically adjust the amount of water to address the mud sand deposition problems. Hydrodynamics has been studied at the university, the principle of enlightenment that the rules of fluid motion. The face of Dujiangyan, I can not imagine what his son was Bing thought to build such a Dujiangyan, is how to calculate this project to calculate the pass to open drainage areas. The more we do not know, the more we can not imagine, the more incredible, the more you can feel the sons and daughters of the intelligence and wisdom, feel the great ancient civilization, to mankind's greatest feat of flood control while proud of. Arrived in the "Second Temple", a ride with a millennium-old buildings, is a history of Li Bing, an official memorial ceremony where the father and son. According to legend, where the first is to commemorate the Shu Wang Du's "look Emperor Temple," after more than 1,500 years ago, to special shrines to commemorate Li Bing and his sons. According to "Guanxian Local Zhi" records, "Every-year-old planting complete, Shu Si Bing Bong candles. An endless stream." Here, you can learn more about the formation process of Dujiangyan, but also on the sixth flood control tactic "Centaur Beach, low for Weir" and the eight-character maxim, "the event of Bay cut angle, every now pumping heart", with a deep understanding of the image. Here, I got to see Li Bing, the stone was worshiped as it was when the people found in river clean-up. Li Bing, Warring States period, strategist and chief scientist. BC 250 years, from the ancient Shu Qin sent to any county governor, that is, Mao Tse-tung said, Li Bing, governor of Sichuan. During his tenure, the people, anxious people from untold miseries, in order to remove the Minjiang River floods, climbing wading, examining the facts, study of flood control methods. His grand political ambitions and scientific minds as well as country and the people's sense of responsibility to mobilize the unprecedented construction of Dujiangyan, the great feat of bearing in mind the future generations! Although history books, there is no record of his life, even people still do not know the year of his birth and death, but the ancestral Shuzhong people, has been mind him, admired him. I think Bing is also regarded as ambitious as Chief Executive. In ancient times, such as scholar-Chief Executive is still able to appreciate the people, concerned about the weal and woe of the people come up with the construction of Dujiangyan silver, "Crown 1, the benefit side," some of our scholar-Chief Executive for the people are doing, it not do should be ashamed! After a "second Temple," Po-bottle came from the pile on the "Fu-concept", which will be enjoying a sit qu shui Neijiang and the diversion of the pavilion. Come here, one looked, among the vast expanse of whiteness of the rain and fog, are somewhat vague unrest and anxiety, many coming from the depths of the earth tremble, between heaven and earth reverberating with roaring, such as the boring landslides, tsunamis, such as mad at first, then a huge power, it seems that nothing can stop. Seen along the sound came up, we saw that the surging river from the scuttling of the vast influx of gate ---- Po bottle drains leading to Shuzhong farmland. Fog, the river rolling, roaring forward, roared, following more than two thousand years ago to give it to set a good direction, obedience to flow down. Under the rain still, rain and fog filled the air, the vast non-vision. The sky is white, the mountains are white, the water is white, the only Dujiangyan, dignified way across the heart. Watching the river watershed from the fish head embankment rolling Look at Alan ambiguity in the Pentium Suspension Bridge across the river, the people as much as an incomparable feeling of insignificance. Overlooks the whole project, although rain and fog cover the distance of the mountain, but the images from that subtle, the feeling of the river torrent, the Rain in the readiness to stay, the experience with the project majestic and magnificent, feel the rich history and the the years of vicissitudes. Dujiangyan water irrigation of farmland, to Shu Zhong regional political, economic and cultural development has created the decisive conditions for the Southwest region of civilization's progress. The completion of Dujiangyan, changed the status of local agriculture in Sichuan, "floods, droughts and from the people, I do not know hunger, when no famine, the world is that of the Tianfu of it." It is precisely because of the Qianwan Mu Dujiangyan irrigation farmland, and promoting economic development, social stability, and powerful, coupled with difficult terrain surrounding the sake of the Shu kingdom in Chinese history status, only to Sichuan to become the glorious country in Chinese history . Dujiangyan City, received the Office of the comrades also said that there is not due to the impact of natural disasters, agriculture developed, people may live in peace and stability, promoting the development of culture and education, which is created in Sichuan as many politicians, military strategist, writer important reasons. Sichuan since ancient times, talent and accomplishments are striking, more or less related to the credit of Dujiangyan. When leaving Dujiangyan, days late, the rain has stopped, only thoughts are still filled with countless. Volatile water, life is short, but history will not forget those who contribute to society. No matter what the age is often of Crown, should be like a father and son as Li Bing, diligent perseverance, doing a socially meaningful people.
