The strongest travel live broadcast

Chapter 474 Project No. [-]

"It is said that a long time ago, a shepherd named Kurban came to TLF to graze his flocks of sheep.

At that time, the shepherd was looking for a place with lush water and grass under the wind and sand all over the sky. He searched and searched, and finally found a depression with green grass, but the depression was too small to meet the needs of the sheep, so Kurban went to I started looking for new pastures, and finally found a few depressions.

The areas of these depressions are not large, the same as the previous ones, but they are covered with lush green pastures. Kurban wants to dig a small river to connect all the depressions. The longer the grass grows, the more lush it will become. pasture.

So he began to use a shovel to find water in the depression. When he dug two feet deep, the water gushed out from the ground. He took a sip. The water was cool and sweet, and it could be said to be life-saving water.

But several depressions are far apart, how can the water be communicated?

He began to dig the canal, but he had only dug about ten feet. The strong sunlight at noon shone in the canal, the water was evaporated, and the wind blew the yellow sand, and the canal was filled again. Kurban simply started The result of digging underground drains is that they are no longer afraid of the sun and sand.

However, in order to know where the culvert was dug, he dug another hole into the ground at intervals. After dozens of days of hard work, he connected several depressions and counted how many were exposed on the ground. Ten wellheads.

It is said that this is the first Karez of TLF, so everyone should be able to understand what Karez is.

Regarding the legendary story I just mentioned, you can refer to page 3 of "XJ Comprehensive Practice Activity Book for the 33rd Grade Primary School", haha. "

However, Zhang Yang looked at the sand table in front of him that simulated the principles of the Karez water conservancy project, and named the three most important people for this water conservancy project, but someone raised doubts about the third person he mentioned.

"No, as far as I know, didn't UNESCO include Iran's Karez in the "World Cultural Heritage List"? Why isn't it our country?"

"So that means that this water conservancy project was only promoted during the Qing Dynasty?"

"But isn't this just an irrigation facility? How can it be comparable to the Beijing-Hangzhou Grand Canal and the Great Wall? It shouldn't be qualified, right?"

"I just checked on the Internet. It seems that this Karez is also available in Persia."

Zhang Yang naturally knew about these situations, so he didn't even say that Kurban was the inventor when he was explaining just now, he just said that the first Karez on the TLF side was dug out by that Kurban.

In fact, who is the earliest inventor?Which country made it first?That's something that historians need to study. Zhang Yang is just a travel anchor, not a researcher of history, he just needs to tell fans about the situation.

"That's right, Persia, Iran, and our country all have facilities similar to this kind of Karez. Let's not go into details about the other two countries, or we will talk about it when we have the opportunity to go abroad in the future. I will say it first. Let's talk about our country.

You can first understand the structure of Karez, which is generally composed of four parts: a vertical shaft dug downward, an underground horizontal channel, a ground channel and a small reservoir.

Song Shenghongzhi of the Southern Dynasty recorded in "Jingzhou Ji": There is Li Village in the north of Sui County, and there is a heavy mountain in the south of the village, and there is a cave at the foot of the mountain.

According to the legend of the elders, there are two moats in the west of Linxi, where Shenlong was born, and there are [-] acres of land around it, and there are nine wells in the center.

It is also said that if one well is drawn, the water in all wells will move, that is to say, it will be used as Shennong Shrine, and it will be shrine every year.

Nine wells are connected by themselves, and one well affects all wells. What I said just now is actually a facility similar to Karez. It has the same structure as the Karez that communicates with underground canals. Shennong is the legend of agricultural and medical inventions in my country. If Chuanjing is connected with him, it can be seen that it has a long history.

Sima Qian also said in "Historical Records The Five Emperors": Gusou (gǔ sǒu) made Shun go through the well again, and Shun went through the well to escape from the empty side. Go out empty.

When Shun went through the well, he dug a "Nikong" from the side, that is, a tunnel, which is very similar to the excavation method of Karez. If "Nikong" is a horizontal tunnel, it is Karez. This record is more than the legendary Persian. Kanjing's is more than 1000 years earlier.

As for why I said that Karez can be compared with the Beijing-Hangzhou Grand Canal and the Great Wall, although this view has not been recognized by most people, and some people have never heard of it at all, but we have to say that Karez is also a miraculous water conservancy project .

To understand this, you need to understand the working principle of Karez. You can take a look at the sand table in front of us, which is to lead the groundwater from the melting ice and snow on the Tianshan Mountains to the TLF Basin for agricultural irrigation.

Because the Tianshan Mountains block the air with moisture in the north, the northern part of the TLF Basin has become a flaming mountain, and there is not much water in the basin. Therefore, if there is no Karez, the TLF Basin is not suitable for survival at all, let alone such prosperity. .

According to the statistics in 1962, there are more than 1700 Karez wells in our country, with a total flow of about 26 cubic meters per second and an irrigated area of ​​about 50 mu.

Most of them are located in the TLF and Hami basins. For example, there are more than 1100 karez in the TLF basin, with a total flow rate of 18 cubic meters per second and an irrigated area of ​​47 mu, accounting for 70% of the basin’s total cultivated land area of ​​67 mu. It is of great significance to develop local agricultural production and meet the living needs of residents.

According to my understanding, as long as it is a project that is beneficial to the people, and it is indeed extremely difficult to build here, after all, this is a water conservancy project that only appeared on the extremely arid Gobi Desert, even after passing through the Flame Mountain, then I think It deserves the title of the third largest project in our country. "

In front of the sand table, Zhang Yang stood for about 10 minutes, and as he talked eloquently here, he also aroused the approval of some tourists around him who also came in to visit.

As soon as the voice fell, there was a burst of applause beside him. Zhang Yang, who was immersed in the explanation just now, was attracted by this burst of applause. When he turned his head, he realized that more than a dozen tourists had been attracted to him unknowingly.

Among them were men and women, old and young, and some old men looked at him with admiration and said.

"Young man, what you said is very good, old man, I feel that this trip is worthwhile. Yes, as long as it is a project that is beneficial to the people, then he deserves our praise, even deified it."

"That's right, this is a great project that affected the basin with the snow water from the Tianshan Mountain across the Flame Mountain. Lin Zexu and Zuo Zongtang can really be said to have made great contributions to the people here. It is not an exaggeration to say that it is the grace of life, I remember seeing the statues of them when I just came here!"

Why do the old men say that, combined with the wave that Zhang Yang explained before, a few young tourists suddenly realized.

"I said, why are there statues of Lin Zexu and Zuo Zongtang in the TLF museum? It turns out to commemorate them. I've learned a lot!"

"Hey, are you that travel anchor Zhang Yang? Let me tell you, a man, a woman, a drone, and a monkey and a dog. This combination is too familiar. I just saw the news this morning. , Did you help the relevant departments here to destroy a gang of human traffickers yesterday?"

"Ah?!! So it's him. The news this morning is almost overwhelming. I didn't expect that we could see a hero here, haha!"

"Oh, there is such a thing. Then this young man is really good. He knows how to speak well, and he is brave enough to do justice. This is a rare talent in today's society!"
