One-day tour route of Dujiangyan and the best strategy

Dujiangyan is a miracle of ancient water conservancy projects in China with a long history of more than 2,000 years. It is still well preserved, and its function and scientific structure have been tested for thousands of years. As sons and daughters of China, we are proud of the wisdom of our ancestors. Here are some detailed strategies to share with you.

Dujiangyan is a county-level city, about 70 kilometers away from Chengdu. The name naturally comes from the famous Dujiangyan water conservancy project. In addition, Qingcheng Mountain, a famous Taoist mountain, is also located in Dujiangyan.

One weir and one mountain constitute the foundation of Dujiangyan tourism. There is a saying that "worship Dujiangyan and ask Qingcheng Mountain".

You can also see pandas, including Panda Valley and Panda Paradise. The former is engaged in the research on the wild release of giant pandas, from rescue, artificial breeding to wild release. The video of online panda climbing trees was basically taken here. The latter is the place where giant pandas have been sent overseas.

Dujiangyan is a good choice if you want to see pandas and avoid crowds. Brother Xiao Zhang came to Dujiangyan for the legendary weir and mountain, because he has been to the giant panda base.

Dujiangyan cuisine: scallion rolls, stewed chicken with ginkgo, Qingcheng old bacon, Taoist pickles, beef bean curd, palm chicken, fried loach, noodles with dregs, ham and shredded chicken rolls.

Dujiangyan specialties: Qingcheng tea, Dong Tian milk wine and Du Jiang bluestone tools.

Traffic guide

To Dujiangyan, you can go to Chengdu first. From Chengdu to Dujiangyan, you can choose bus, train or drive by car.

Bus: One trip can be checked and bought, with many trains, and the driving time 1~2 hours depends on the place of origin.

Train: Chengdu Railway Station or Xipu Station, take the train to Dujiangyan Station, which takes about half an hour by car.

Self-driving: Turn on the navigation and follow the voice guidance of Lexus/Xiaoyueyue/Sister Degang Guo. The driving distance is about 1 hour for 20 minutes.

My itinerary

Zhang Ge in Dujiangyan is a one-day tour. One day is enough without going behind Qingcheng Mountain. I chose a product with enough transactions and the most expensive price on a treasure. Facts since then have proved that this choice is good.

Departure on 1 day-Dujiangyan-Qingcheng Mountain-Return trip

Route of Dujiangyan Scenic Area: Lei Yu-Erwangmiao-An Lan Bridge-Yu Zui-Feishayan-Baokoukou-Nanqiao-guanxian Ancient City. It's easy to walk from top to bottom from Lei Yu. You can choose this route by car, otherwise you can only take the mass route, enter from the gate of Libi Park, and then climb the mountain.

Route in front of Qingcheng Mountain: Shanmen-Yuecheng Lake-Buyun Gallery Cableway-Shangqing Palace-Laojun Pavilion. Take the easiest route to the top of the mountain, and then go down the mountain by the original road, instead of taking the ancestral temple in Shi Tian Cave.

A source of abundance

Sichuan has fertile land and rich products, and has been called the land of abundance since ancient times. However, "since ancient times" here is not unprecedented.

The term "land of abundance" first appeared in the Warring States policy, referring to Guanzhong area. By Zhuge Liang's "Longzhong Dui", Tianfu became Yizhou, which was later Shu State, which is now Sichuan.

Dujiangyan is the key to Sichuan replacing Guanzhong as Tianfu. Dujiangyan was built at the end of the Warring States Period, and Qin destroyed the ancient Shu, accounting for 60 years in Shu.

During these 60 years, Shu did not contribute to Qin, but became a drag on Qin because of repeated riots. In ancient times, the most common cause of riots was that people had no food.

Until Zhao Haoqi, the king of Qin, named Li Bing the prefect of Shu County. Li Bing led the people to build the longest water conservancy project in the world.

He was finally subdued by the surging Minjiang River.

The Chengdu Plain, which was once either drought or waterlogging, has become a land of abundance. Even after more than 2200 years, Chengdu can become the leisure capital, which is related to this.

This Dujiangyan is really worth visiting.

Day 65438+0 am

Lei Yu-Erwangmiao-An Lan Bridge-Yu Zui-Feishayan-Baokoukou-Nanqiao-guanxian Ancient City

The silk river with beautiful spring scenery floats between heaven and earth, just like a cloud beside the jade peak, between ancient times and the present.

-"Climbing the Building", Du Fu

Du Fu's poems are more famous than Lei Yu's. Lei Yu is located in the northwest of the city, on the east bank of Minjiang River. The trip to Dujiangyan started from the mountain. As I said before, this tour sequence is very scientific, with two words from top to bottom: labor saving.

On the Lei Yu, you can have a panoramic view of Dujiangyan.

There is a Leiyuting on the mountain, which is an ancient building. In addition, there is a spectacular walking elevator connecting Lei Yu Pavilion and Erwang Temple. It's a piece of cake to go to the Erwang Temple.

Behind the corridor leading to the top of the mountain is the escalator.

The Erwang Temple was built to commemorate the achievements of Li Bing and his son in water control. On the inner wall of the temple are written the formula of "deep scouring beach, low weir" and the three-character sutra of water control.

Li Bing managed water all his life. After the completion of Dujiangyan, he also presided over many water conservancy projects. Due to long-term fatigue, he finally fell on the construction site for managing Shiting River ... This is a focal figure. Now the people in the irrigation area have worshipped Li Bing and his son as gods.

Out of respect, I didn't take pictures at the Erwang Temple.

Out of the Erwang Temple, you can see An Lan Lock Bridge when you come to the river. An Lan Bridge, also known as Lovers Bridge, was built by a couple named He in the Ming Dynasty. At first, there was no guardrail on the bridge, and someone accidentally fell off the bridge and died. The responsibility falls on Mr. He. He was sentenced to death by local officials, and then his wife tried to repair the handrail of the bridge.

Perhaps in places related to love, couples like to make wishes, and there is a wall by the bridge, which is full of yearning for beautiful love. The bridge body shook badly when crossing the bridge, but there were guardrails on both sides to prevent it from falling.

Cross the An Lan Cable Bridge and go to Yu Zui. Fish mouth is one of the three major projects in Dujiangyan, and its full name is fish mouth diversion dike. Standing in front of the guardrail of the fish mouth, looking at the Minjiang River feels that the current is big and urgent.

The fish mouth divides the rolling Minjiang River in two. The outer river is wide for flood discharge and the inner river is narrow for irrigation. Water diversion is only its basic function. In fact, the fish mouth can also play the role of water diversion and sediment discharge, which is called "46 water diversion and 28 sediment discharge".

As shown in the following figure, during the flood period, the water level is high, the cross section of the outer river is larger than that of Neijiang, and a large amount of water goes from the outer river. During the dry season, the water level drops, and the cross section of Neijiang is larger than that of Waijiang, so most of the water can be used for irrigation. This is the role of water regulation.

In addition, there is little water in the dry season and there is almost no sediment in the water. During the flood period, because the flow of the outer river is greater than that of the inner river, most of the sediment goes from the outer river, and most of the sediment is deposited in the outer river due to the erosion of the concave bank and the deposition of the convex bank. This is the role of dredging.

It's less than one kilometer from Yuzui of Jingang levee to Sha Fei weir, and only ten minutes' walk. This section of the river is gradually sinking, and the water flow is more turbulent.

Sha Fei weir is the biggest black technology in Dujiangyan project.

Its function is "flood discharge and sediment discharge". Although 80% of the sediment is discharged to the Waijiang River through the adjustment of the fish mouth, 20% remains in Neijiang, which is still a threat during the flood season.

The river in Neijiang has a bend here. Due to the centrifugal force, the water level in the concave bank is very high. Because of the high water level in concave bank and the low water level in convex bank, lateral circulation is formed.

Because the river is clear, the sediment stones are mainly at the bottom, and the sand and gravel will be thrown into the outer river through lateral circulation. 15% of the sediment can be filtered out by flying weir, and only 5% of the sediment will remain in Neijiang. As shown in the figure below:

Schematic diagram of Minjiang section where Sha Fei weir is located.

Above is the flood season and dry season, and the flying sand weir will surface. The flying sand weir we see most of the time is a beach full of gravel.

At this time, there is no need to flood, and all the river water is left in Neijiang for downstream irrigation. Therefore, the height of the flying sand weir needs to be skillfully built.

Treasure Bottle Mouth, next to Sha Fei Weir, is a narrow passage dug in Lei Yu Mountain. This is the hardest part of the whole project.

In ancient times, no explosives were used to cut mountains. Facing the Rocky Mountains, it is almost impossible for human beings to finish the excavation. The solution is to burn it with fire and then quickly cool it with water, so that the rock will burst.

Even so, digging for eight years. This piece separated from the original mountain is called the retaining pile, and the water inlet between the old mountain and the retaining pile is the bottle mouth.

The bottle mouth is mainly used to control the amount of water, so that there is a stable water flow downstream. Calculate the width of the original mining. At the same time, it also has the function of "drawing clean water and discharging muddy water". As shown in the figure below:

The surface flow is clear water and the bottom flow is muddy water. Under the action of circulation in the bend, clear water enters the bottle mouth, and muddy water returns to the outer river from one side. Due to the narrowing of the entrance, backflow is formed by the side, which washes the sediment to the flying sand weir.

The Minjiang River, which runs down from Minshan Mountain, with a lot of sediment, passes through three checkpoints: the fish mouth, the flying sand weir and the bottle mouth, and becomes a trickle that moistens the Chengdu Plain.

Dujiangyan, the source of abundance.

Li Bing, benefit all generations!

Dujiangyan gives people a natural feeling. Nowadays, most water conservancy projects are damming rivers. I used to think that Dujiangyan was the same. It is said that during the War of Resistance against Japanese Aggression period, the Japanese army sent a plane to blow up Dujiangyan, but when the plane arrived here, it did not find the imaginary dam and gave up.

Then leave Dujiangyan scenic spot from the gate of Lidui Park. There are also some small scenic spots along the way: Fulongguan, Zhang Song and the like, as well as imitations of iron columns that sank at the bottom of the river as mud-digging rulers. The main entrance of the scenic spot is the South Bridge.

The South Bridge, which was built in the fourth year of Guangxu in Qing Dynasty (1878), was destroyed by wars many times and was washed away by floods. Today's South Bridge was restored after the Wenchuan earthquake in 2008, and the pattern on the top of the corridor is exquisite.

The night view of the covered bridge is one of the iconic beauty of Dujiangyan. Since Brother Xiao Zhang lived here at night, he naturally missed it. I'll give you a net map for your reference.

Dujiangyan, the ancient city of guanxian, was called guanxian in ancient times. In fact, this is the urban area of Dujiangyan in ancient times. There are shops along the road, which is very commercial. I don't know why I like the feeling of this ancient city. I don't know.

At noon, I was dragged to a restaurant, where I could have a meal and watch a wonderful performance. This was a highlight of the day's trip, but unfortunately I didn't remember the name and place.

After dinner, take a bus to Qingcheng Mountain more than ten kilometers away.

Qing cheng zhi Qing

Qingcheng Mountain, a famous Taoist mountain. During the Eastern Han Dynasty, Zhang Daoling (Zhang Tianshi) founded Taoism in Shi Tian here, and respected Laozi as the ancestor of Taoism in the Spring and Autumn Period, from which Taoism was born.

There are two ways to get the name Qingcheng Mountain. First of all, it was originally named Qingcheng Mountain because of the legend that "Du Qing, Wei Zi and heaven and earth live together". Emperor Xuanzong of the Tang Dynasty thought that when he wrote the imperial edict, he mistakenly wrote "Qing" as "Qing", which was handed down from then on. Secondly, Qingcheng Mountain has lush trees, evergreen seasons and surrounded by peaks, so it is named Qingcheng Mountain.

There are four wonders in Qingcheng Mountain. Don't get me wrong, this is not a martial arts move. One must-see tribute tea, two must-see ginkgo roast chicken, three must-see Taoist pickles, and four must-see Dong Tian milk wine. It's all food and drink Zhang Daoling's disciples have a good life.

Besides Zhang Daoling, there is also a celebrity at the foot of Qingcheng Mountain. Oh, no, it's a snake lady white snake. There is a song to prove it: The White Snake under Qingcheng Mountain has practiced this body in the cave for thousands of years.

Haha, here comes the mountain gate. Let's go up the hill.

DAY 1 afternoon: Shanmen-Yuecheng Lake-Buyun Gallery Cableway-Shangqing Palace-Laojun Pavilion

Qingcheng Mountain is divided into front mountain and back mountain. The area of Qian Shan is relatively small, and there are many buildings in Guan Gong Temple, which can be visited in half a day. The back hill is dominated by embracing nature, with a large area, and it takes a day to walk. Brother Xiao Zhang travels in Qian Shan.

I have already felt the green of Qingcheng Mountain near the mountain gate. Needless to say, Metasequoia glyptostroboides on both sides of the road are tall and straight, and even the trunks and stones are covered with a thick layer of moss.

The road up the mountain is paved with plank roads, and it creaks when you go up. The trees along the road can only be described as covering the sky, and the whole light is dimmed.

Soon I arrived at Yuecheng Lake. I didn't expect such a lake on the mountain. The lake is small, but it is also living water. The stream that flows into the lake originates from Xiao Lao Peak.

The cruise ship crossing the lake has no power, so it is pulled by steel cables. You can get to the other side in 2 minutes by boat, but you need to wait in line for a while.

After Yuecheng Lake, it is the next stop of the cableway. Buy a round-trip ticket and take the cableway up the mountain. A ropeway is a small car with a ceiling.

Get out of the ropeway and climb the stairs. Soon I arrived at the Shangqing Palace. The plaque above the gate bears Jiang Zhongzheng's signature. It is conceivable that there must be many stories behind this plaque that can be preserved to this day.

There is a courtyard in Shangqing Palace, surrounded by Laojun Hall, Sanqing Hall, Daodejing Hall, Wuwen Hall and Jade Emperor Hall. Taoist gods are enshrined in it.

The next house is Zhang Daqian's apartment in Qingcheng Mountain. Now there are some of his paintings hanging in it, probably samples, without any protection.

Ask Qingcheng Mountain. It was refined when it came.

After that, it is the summit. Xiao Lao Peak, the highest peak of Qingcheng Mountain, is1260m above sea level.

The journey from Shangqing Palace to Xiao Lao Peak is the hardest part after going to Qingcheng Mountain. Many steps are broken into several pieces, so you need to pay attention to your feet.

On the way, I met many villagers carrying baskets and selling a fruit that I had never seen before. After asking, they called it Snow Lotus. This is definitely not the snow lotus on the Tianshan Mountains.

I didn't want to buy it at first, but my aunt sold it with great enthusiasm. The fairy was persuaded and bought one. The juice is rich and slightly sweet. If you don't bring water, you can use it to quench your thirst. Not bad.

Reach the top of the mountain in half an hour.

There is an old gentleman's pavilion at the top of the hill. The original statue of Taishang Laojun riding a cow, which is 36 meters high, was unfortunately damaged in the Wenchuan earthquake in 2008. Today's Laojun Pavilion is newly built and can't get on.

It's raining on the top of the mountain, and the top of Laojun Pavilion is looming in the clouds. After a few steps, the rain began to get heavier. I didn't bring my umbrella, so I had to hurry back down the mountain.

Going down the mountain is faster than going up the mountain, and I got to the parking lot at the foot of the mountain before 5 o'clock. When I left by car, I remembered Qingcheng Mountain in my mind, and the most impressive thing was Qingcheng Green.
