Chapter 1141 Purchasing all the way
However, the most terrifying thing is that the existence of this reservoir directly led to the complete cutoff of the lower reaches of the Tarim River, causing severe desertification of the downstream green ecological corridor. In the past thirty years, two thousand people in the lower reaches were affected. Thousands of acres of grassland have been degraded and desertified, and large areas of Populus euphratica forests have died and disappeared. As a result, the animals that rely on these oases have disappeared, and many places in the Taklimakan Desert and the Kuruk Desert have "joined together."
All of these have undoubtedly become serious ecological disasters.
At that time, Zhou Zhi was basically sleeping during the journey from Daxihaizi Reservoir and Tarim River Valley to Taitma Lake. Only when he occasionally opened his eyes, he could feel the deathly silence and desolation around him.
After switching to Zhou Zhi in the early morning and driving, the whole road was still filled with dry river valleys and shocking desolation. Countless Populus euphratica forests, which are said to be "undying for a thousand years, not falling for a thousand years, and immortal for a thousand years", could not withstand the rapid changes in the ecological environment. , turned into a withered giant.
It wasn't until the car drove close to Ruoqiang and came to the valley of the Chelchen River, another river originating from the Altun Mountains, that Zhou Zhi saw life again - the group of wild camels running in the morning sun.
The topic of protecting nature sounds like a joke in Shu. Subtropical areas at the northernmost latitudes, such as Zhou Zhi’s hometown of Jiachuan, have strong ecological recovery capabilities. Every year, river beaches are inundated and water recedes. After that, it was bare, but within a month it was covered with green and fluffy grass, wire grass, and by autumn there were reeds and grassweed everywhere. Worrying about the environment felt almost like unfounded worries.
But on the banks of the lower reaches of the Ta River, Zhou Zhi could no longer laugh.
In fact, the Challa Reservoir also has serious problems of water seepage and evaporation in the desert.
The only solution that Zhou Zhi can think of is to reinforce the edge leakage area with cement, and to build a dike around the reservoir to reduce the water storage area of the reservoir and use a method of deepening the water storage depth to ensure the storage capacity. .
Because the reservoirs in the northwest are the same as the plain reservoirs in the lower reaches of the Yangtze and Yellow Rivers, with a depth of only two or three meters. In theory, raising the embankment by one meter can reduce the evaporation area of the reservoir by one-third, while the storage capacity remains unchanged.
If the height is increased by two meters, the surface area of the reservoir can be reduced by half. Maybe the ball-laying idea provided by Zhou Zhi can be used.
Don’t underestimate this idea. Take the Daxihaizi Reservoir as an example. The water storage area is as high as 68 square kilometers, but the water depth is only two and a half meters, and the total storage capacity is only 16.8 billion cubic meters.
But out of the total storage capacity of 6.8 billion cubic meters, the amount of water evaporated in a year is 92 million cubic meters.
For the lower reaches of the Tahe River, where "water is as valuable as gold", if the evaporation area can be reduced by half, the evaporation volume can be controlled by half, resulting in an additional 46 million cubic meters of water per year. It would also be an amazing achievement.
Another way is to build the reservoir into the mountains. Mountain reservoirs can be built very deep, and the temperature in the mountains is also low, which can perfectly solve the evaporation problem and the problem of water leakage on the sandy bottom. The water source will be abundant and uninterrupted, and even the water storage problem can be solved. .
As for after coming out of the mountains, use the ancient wisdom of the Uyghurs to build a pipeline water network by simulating karez wells, build a large number of underground water storage tanks in the middle, and turn the terminals into drip irrigation systems, which can almost solve the entire northern Xinjiang There is a water problem.
Of course, these are all idle chatter based on careful imagination, but except for the final move of the reservoir into the mountains and the underground route out of the mountains, the previous ones are all effective measures that have been adopted by later generations.
Xu's father is in the financial system, and Sun Gong's job has nothing to do with water conservancy projects. Yesterday, Zhou Zhi had a lot of chats with his uncle Ai Yijie, but I guess Ai Yijie doesn't have that much energy to promote it. , being able to do a good job in experimenting with straw lattice to fix sand and prevent wind, Zhou Zhi felt that his trip was not in vain.
However, he is also more transparent now, and he will not force things that cannot be pushed forward. He just tries his best in everything. Excessive exertion often does not bring any benefits to others or himself, but will bring a lot of benefits. troubles.
What's more, he has enough things on his hands now, and his own pot is still not cool, so how can he have too much energy to care about others?
Fortunately, in addition to the casual ecological survey and field investigation, Zhou Zhi also acquired a lot of jade specimens along the way.
For example, black jade, sapphire, topaz, and jasper have long been famous, and their reputation is only lower than Hotan white jade.
Hetian Jasper is the best produced in MNS County, northern Xinjiang, and comes in several colors, from spinach green, sun green, light green to duck egg green, apple green, etc. Among these jaspers, there are also first-class ones with higher value, which have fluorescent and cat-eye visual effects.
However, the price of such jasper material is now the same as that of other materials. We have not yet subdivided jasper to this level. Basically, we still price according to the color, jade, strands and cracks.
The price is much lower than that of white jade. As soon as Zhou Zhi made a purchase, there were a bunch of fine products in the trunk of the car.
In addition, there are Gobi weathered jade materials, strange stones, agate, etc., which are also of great collection value, but now they are still completely cheap.
Unable to take it away, Zhou Zhi only chose a piece of natural weathered Gobi jade shaped like a galloping horse.
The jade next door is actually made of topaz, but it has been beaten away by the wind and sand, leaving only the most lustrous part, which forms the shape of a galloping horse. nice.
A colorful stone like a screen, shaped like the towering mountains of Northern Xinjiang, with white on top and red on the bottom. The material is an opaque agate similar to Alxa. It is also weathered to create hills and ravines, just like the Danxia landform. The mountain peaks are piled with snow, and with a base, it becomes a ready-made table screen.
Giving this to your godfather, he will definitely like it.
The third one is a pure agate rough stone, shaped like a straw sandal, flat up and down, full of magnificent colors and the unique ring-layered texture of agate.
Putting it flat up and down on the desk, this is a natural inkstone bed. Zhou Zhi can imagine how surprised his fourth cousin would be when he received this thing.
As for the Gobi topaz galloping horse, it must be Sui Huaxuan’s new collection.
When they arrived in Urumqi, it was President Zhao and Director Qin who came in person to invite Zhou Zhi to the bank.
At first Zhou Zhi was flattered, but then he realized that Director Qin couldn't bear to see the money in his bag jumping out, and wanted Zhou Zhi to fill the hole quickly.
On this trip, Zhou Zhi bought more than 2.5 million worth of goods from Hotan fellows, and more than 300,000 yuan from the purchasing station, plus more than 900,000 yuan from the Urumqi Jade Carving Factory, and more than 900,000 yuan from the Urumqi Jade Carving Factory, and more than 300,000 yuan from the purchasing station. Some tens of thousands were thrown out, but a total of less than four million were lost.
After calling the more than 900,000 yuan from the jade carving factory, there will only be 1.5 million left in the personal account of Zhouzhi Shudu Branch.
This trip to Northern Xinjiang took a total of eight days. In the blink of an eye, it was already the 12th day of the New Year, and there were only a few days until the new semester started.
Zhou Zhi's pager started ringing non-stop, from school, from home, and even Zhao Xing was picking at him.
Originally, Zhou Zhi wanted to take a train to the capital of Shu with Xu Gang, so that he could enjoy the scenery of the northern country along the way, but now he had no choice but to give up and take a plane back first.
As a city aiding Xinjiang, the route from Shudu to Urumqi has been opened as early as 1987, but the aircraft type is still the Tu-154, so there is no choice, and air tickets are still very popular.
