　　Dear tourists

　　When you come to Turpan, people can't help but ask: how can there be largeoases in places with extremely dry climate, known as "Huozhou" and "Fengku"?What's the secret? The secret is the Karez group distributed in Xinjiang, whichis like the blood of human body, extending to the vast Gobi and irrigating alarge area of Xinjiang. The wonderful Karez is also the most widely distributedin Turpan, becoming the spring of life and the source of evergreen, wateringTurpan's verdant grapes and sweet melons. Now let's visit this world-famousirrigation project.

　　Structure of Karez → construction method of Karez

　　Tourists, now we come to Karez paradise. First of all, please follow me toKarez museum to learn about the construction of Karez.

　　Karez is a kind of underground water diversion project created by theworking people of all ethnic groups living in Xinjiang according to the localclimate and hydrological characteristics. There are about 1600 Karez inXinjiang, among which Turpan is the most concentrated. According to statistics,there are 1158 Karez in Turpan, with a total length of about 5000 km, which isequivalent to the mileage from Urumqi to Harbin. Karez is one of the greatestunderground water conservancy projects in ancient China. It is called"underground canal" by experts in geography. Together with the great wall andBeijing Hangzhou Grand Canal, it is called the three major projects in ancientChina.

　　You may have heard about Karez, but its structure may not be very clear.Now I'll introduce it to you. Karez was called "Jingqu" in ancient times, whichmeans "Jingxue". It is composed of four parts: vertical shaft, undergroundchannel, open channel and waterlogging dam.

　　The reason why a large number of Karez were built in Turpan is inseparablefrom the natural conditions here. First of all, the terrain of Turpan Basin isvery low, with an area of 2085 square kilometers below sea level. Turpan issurrounded by mountains. Every year, a large amount of snow on the mountainsmelts and flows into the valley. When the snow water flows through the Gobi, itseeps into the ground to form a subsurface flow, which provides a rich source ofwater for Karez.

　　Then how is the Karez built? Please see: the construction method of Karezis to find the water source at the snow water undercurrent in the high mountainsand valleys, and then drill a vertical shaft every 20 to 30 meters, the depth ofthe shaft varies from 10 to tens of meters, to gather the groundwater toincrease the water potential, and then according to the terrain, dig anunderground channel at the bottom of the shaft to connect with each well, drainit straight down, and connect it to a distant place Oasis, water will be led outfrom the open channel to the ground for irrigation. Waterlogging dam is areservoir for regulating water quantity. A Karez is generally about 3 km long,and the longest one is usually several Karez connected for tens or even hundredsof kilometers, in which there are at least dozens of shafts and more than 300shafts. The shaft in the upstream is relatively deep, up to 100 meters in somecases, and the shaft in the downstream is relatively shallow, generally only afew meters. The function of Karez is to avoid water evaporation. This project isa great innovation to adapt to the characteristics of dry climate. What isparticularly praiseworthy is that the local people rely on their hands andsimple tools to dig deep wells and underground canals. The vastness of theproject and the ingenious structure are amazing.

　　I would like you to recall that when we drove near Turpan City, we couldsee piles of round earth bags down the slope on the Gobi outside the lush oasis,extending to the oasis in an orderly way. Those are the vertical wellheads ofKarez. If you look down from high altitude, those mounds are like necklaces tiedwith pearls, decorating Turpan, an ancient but still youthful place.

　　Reasons for the construction of Karez → origin of Karez tour guide ofXinjiang general situation tour guide of Putaogou in Turpan tour guide of Niyasite

　　Now let's talk about the reasons for the construction of Karez. Due to thedrought and less rain in Xinjiang, the amount of evaporation is large, and theKarez is an underground channel for water delivery, with small evaporation andstable flow, which can be irrigated by gravity all the year round. In addition,the soil here is calcareous clay, so the dug Karez is very solid and not easy tocollapse. The temperature of snow water in high mountains is very low, if directirrigation is unfavorable to the growth of crops, while the surface temperaturein Turpan is very high, the temperature rises naturally after snow water flowsthrough Karez, which is very suitable for watering crops. Therefore, in thelong-term struggle against drought, people of all ethnic groups in Xinjianginvented this method of digging wells and irrigating fields. A Karez is a freshspring that is not dry. It forms the lifeline and lifeline of Huozhou, whichmakes Xinjiang, a place with little rainfall, accumulate water and become anindispensable spring of life in Xinjiang people's life.

　　There are always three theories about the origin of Turpan Karez: one isthe theory of Guanzhong well canal in Han Dynasty. This view holds that the"well canal method" invented by people in Han Dynasty was introduced intoXinjiang and developed into Karez now. The second is related to Lin Zexu. AfterLin Zexu was exiled to Xinjiang in the late Qing Dynasty, he went through Turpanin 1845 and found that it was hot and rainy. So he carefully checked the terrainand water sources, and guided the people of Xinjiang to invent this method ofdigging wells and irrigating fields according to their own geographicalcharacteristics. The third view is that Karez was first created by the Persiansin Western Asia 2500 years ago and later passed down to Xinjiang. Of course,these three views need to be verified.

　　But what I want to tell you is that the distribution of Karez on the earthis connected with the Silk Road, which connects Eastern and Western cultures.Karez have been found in Pakistan, Iran and along the Caspian Sea. Therefore, itis no exaggeration to say that Karez is a pearl in the world cultural heritage.Until today, Karez still plays an important role in the agricultural developmentof Turpan, Xinjiang.

　　Karez open channel → Karez culvert

　　After visiting the Karez Museum and walking out of the museum, you can seethe clear spring beside the road. This is the pure snow mountain water flowingout of the Karez canal. It is crystal clear. If you reach for it, you will feelcool. It's really "crystal clear and cool".

　　The underdrain of Karez can only be seen when you enter the cave. You canonly see the water gurgling in the underdrain, which makes you feel very happy.There are thousands of such wells and canals in Xinjiang. The total length ofthe underground rivers is twice as long as that of the Great Wall, and far morethan that of the Beijing Hangzhou Grand Canal.

　　Tourists, today's Karez is not only an important water conservancyfacility, but also a great cultural landscape for Chinese and foreign tourists.In particular, a folk song and dance performance full of Xinjiang Uygur strongcustoms in Karez paradise will make you feel restless. The bright rhythm, lightmelody and passionate mood make you join them while enjoying. You can't helpsinging and dancing like Uygur girls and young men, and feel the pure fun ofthis song and dance hometown.

　　Ladies and gentlemen, the melodious singing in Karez paradise has alreadybeen sung. Now, please go to enjoy it!
