This matter will eventually need to be handled by Yaoguang Environmental Management Company, so he not only needs to hand over relevant technical information to Yaoguang Environmental Management Company, but also needs to explain the ins and outs of the matter clearly.
Otherwise, the employees of Yaoguang Environmental Management Company will not know what they are going to do, and Zhao Yi's own thinking may not be completely correct, and the inappropriateness needs to be corrected by Yaoguang Environmental Management Company itself.
A day passed with experimental testing and arranging some matters. It was not until the next day that Zhao Yicai told the leaders of the Ministry of Water Resources who met last time some of the results of the experiment here.
It may be that they received the experimental situation from Zhao Yi the next day and needed to find experts to discuss and evaluate the entire plan, so there was no clear reply the next day.
Zhao Yi himself built a weather analysis system to simulate and predict the subsequent impacts of this plan, but he was just empty-handed.
After it is built, the meteorological department needs to provide detailed meteorological data. After these data are filled in, the accuracy of the simulation will be higher and it will have a certain reference value.
Thanks to the help of primary artificial intelligence, this weather simulation system was set up in one day. In addition to performing weather simulations independently, it can also be linked with the earth simulator to become the weather simulation system of the earth simulator.
He plans to put the weather simulation system directly into Tianwen University of Information Technology. They themselves need such a weather system, and they also need detailed weather data.
Therefore, there is no need to run this system on his own server. If the national meteorological department wants to install such a weather simulation system internally, it is also possible.
In fact, there is no need to keep the system confidential. At most, it is to prevent others from using it for commercialization. On the contrary, the data inside is very important and requires close cooperation from the national meteorological department.
On the third day, the leader of the Ministry of Water Resources replied to him an email, asking him to attend a multi-department joint meeting in the afternoon. The departments present included the Ministry of Agriculture, the Ministry of Land and Resources, the Ministry of Water Resources, the Meteorological Bureau and other departments.
Perhaps he had reached a preliminary conclusion in the past day. This multi-department joint meeting was regarded as a formal discussion of his previous proposal.
After receiving the reply, this was a good start for him. What he was most afraid of was that without even a preliminary conclusion, the subsequent plans would not be implemented.
It's just that he originally planned to take a break before the annual meeting, but he finally caught up with this major event. If he wanted to reach a broad consensus on this matter, it couldn't be done in one meeting.
This meeting may just show the attitude of various departments towards this matter. The progress of subsequent issues also needs more scientific data support. The bigger the matter, the more careful verification is needed, and it cannot be carried out blindly.
When Zhao Yi arrived at the meeting venue in the afternoon, there were already many people inside. Zhao Yi found his seat and sat down until the meeting officially started.
About 20 minutes later, everyone may have arrived, and the meeting officially started. This matter was led by the Ministry of Water Resources, so the leader of the Ministry of Water Resources made the speech at the beginning of the meeting.
I saw the leader said: "Some time ago, we held a discussion meeting on solutions to the water shortage problem in the northern region. At the meeting, we discussed three measures: South-to-North Water Diversion, seawater desalination, and artificial rainfall enhancement in the Northwest.
After careful discussion, I feel that all three measures can alleviate the problem of water shortage in the north to a certain extent, but they also have their own advantages and disadvantages.
Although the South-to-North Water Diversion Project may not necessarily be the most expensive, its fatal weakness also exists, that is, the total annual water transfer volume is a drop in the bucket compared to the water shortage problem in the entire north, and it can only focus on solving the water shortage problem in some areas.
The second one is seawater desalination. According to Academician Zhao, seawater desalination is used to replace urban water, reduce the consumption of terrestrial freshwater resources by the urban water supply system, and use these water sources for ecological restoration and agricultural irrigation.
This approach is also a relatively feasible solution. According to Academician Zhao’s assessment, by improving technology and delivering desalinated seawater to users’ homes, the price per ton can be around 0.5 yuan.
Although the price of water supply is a bit higher than that of most cities now, I think it is still acceptable, especially compared with people's income, it is still affordable.
At present, the per capita water consumption of urban residents in my country is about 200 tons. For a family of four, the annual cost is about 400 yuan. According to some statistical analysis, in December last year, the domestic per capita income was 1,205 yuan.
Moreover, with the seawater desalination plan, there is no need to be limited by the water volume of the water source, and almost unlimited supply can be achieved. Moreover, the price of 0.5 yuan per ton also eliminates the need for the government to subsidize tap water fees.
Therefore, comprehensively speaking, this plan is more cost-effective than the South-to-North Water Diversion Project, and can also effectively solve the water shortage problem in parts of North China and Northeast China.
The only disadvantage of this solution is that the distance it benefits cannot be too far from the coast, and the altitude cannot be too high. If the altitude is too high, the cost of electricity consumption and pipeline laying will be high during the process of transporting water resources.
We all know that the northwest is thousands of kilometers away from the Bohai Sea, and the population density there is relatively low and the altitude is relatively high. The cost of building pipelines is spread into the water price, accounting for a relatively high proportion.
More importantly, in addition to water shortages for daily life and industry, the water shortage problem in agriculture is also very prominent in the northwest region. It is not impossible to solve it, but the investment scale is too large.
At the meeting, some experts proposed using the method of convergence of low-altitude and high-altitude water vapor to form rainfall from high-altitude water vapor drifting over from Xinjiang to solve the water shortage and climate problems in the northwest.
However, we have calculated that to achieve a certain effect, 100 billion cubic meters of fresh water need to be transported to the Northwest or Lop Nur every year, so that Lop Nur will form a water area of 16,000 square kilometers.
After careful discussion, we found that this method is theoretically feasible. It can at least restore the climate environment of the Northwest during the Qin and Han Dynasties. By then, the climate of the Northwest will be fundamentally changed.
However, you should also guess that the difficulty of this method is that the amount of work is too large and the cost is also very huge. To achieve the above effects, it will take about 40 years and the total investment will be more than 2 trillion yuan.
The third option is artificial rainfall, which uses emerging science and technology to allow high-altitude water vapor in Xinjiang to rain. According to the arguments of relevant experts, more than 1.6 trillion tons of water vapor floats over Xinjiang every year, while only tens of billions of water vapor fall every year. Around tons.
This shows that the high-altitude water vapor in Xinjiang has huge utilization value. As long as this high-altitude water vapor can be trapped in Xinjiang in a cheaper way, then Lop Nur will naturally recover naturally without the need to send water from east to west.
Therefore, after a comprehensive comparison, we believe that the third option is the most cost-effective and most effective option, and this meeting is to discuss the feasibility of the third option. "
At this time, the leader of the Meteorological Bureau said: "According to our observations, the climate conditions in the northwest are much better than before, and the overall water shortage in the northwest has been alleviated to a certain extent.
This is due to the remarkable results of land management carried out by Yaoguang Environmental Management Company in the northwest region over the years. Rainfall has increased by about 20% compared with the past, and evaporation has also slowed down significantly.
If industry is developed on a large scale and agricultural reclamation is carried out on a large scale, and land resources in the northwest are reasonably planned and developed, the water shortage problem will not be particularly obvious in general. "
"I don't agree with your point of view. Although the basic water consumption of personnel may be better than before, when compared with the national per capita water consumption, the gap is still very obvious.
Moreover, the domestic economy as a whole is currently strong in the south and weak in the north. The reason for this pattern is that in addition to some trade convenience factors, the relative lack of water resources is also one of the important reasons.
The country now advocates balanced development, but the shortage of water resources has caused the development of northern industry to be relatively slow. The country is unable to do anything if it wants to carry out layout in this area.
Therefore, I think we must do our best to solve the climate problem in the northwest. This is not only a matter of developing the northern economy, but also an issue of improving people's livelihood in the north.
And some time ago, I also went to the Badain Jaran Desert and looked at the land management issues there. Although most of the areas were planted with trees by the Fluolight Environmental Management Company.
However, due to the heavy sandstorms from the northwest and the dry climate, there are still certain erosion problems. Yaoguang Environmental Management Company currently needs to spend huge costs every year to maintain the environment in the remote areas of the Badain Jaran Desert.
Therefore, the northwest region is not without water shortage. The current performance is not bad. Basically, it relies on the continuous support of Yaoguang Environmental Management Company to achieve the current state.
The reason why Yaoguang Environmental Management Company is able to transform the Badain Jaran Desert and the Tengger Desert mainly relies on the water sources of Xiutuze, Baitinghai and Jilantai between the two places.
It would be much more difficult to advance to Fudi, Gansu Province and transform the desertification there. This is why the Yaoguang Environmental Management Company has stopped at the Badain Jaran Desert.
Although the climate in the northwest is indeed much better than before, it is not much better. If the current situation is to be maintained for a long time, huge manpower and material resources will be spent every year to maintain it.
This is because the climate in the northwest has not been fundamentally changed and can only be regarded as an improvement. If the climate in the northwest can be fundamentally changed, I personally agree with it. "
Although I don’t know which department the leader or expert who spoke came from, his speech was indeed sonorous and powerful, pointing out the fact that the fundamental climate problem in the northwest has not yet been solved.
After hearing these remarks, people from the Meteorological Bureau hurriedly said: "We are not in favor of improving the climate problem in the northwest region, but there are several problems that must be solved.
The first is a technical issue. Although artificial rainfall seems feasible, if traditional dry ice rainfall is used to achieve a certain effect, the cost is no less than that sent from east to west, or even more.
The second question is whether the climate change in the northwest will bring about a wider climate chain reaction, causing the climate conditions in other regions to develop in a worse direction.
If these two issues cannot be concluded well, then I personally hope that this matter should be carefully considered to avoid unpredictable problems. "
When the leader of the Ministry of Water Resources heard this, he took over and said: "Regarding these two issues, we actually already have preliminary technical implementation plans, otherwise we would not be interested in artificial rainfall.
First of all, we have convened experts to discuss that if there is sufficient low-altitude water vapor, it can indeed allow low-altitude water vapor and high-altitude water vapor to converge to form stable rainfall conditions.
As long as we can provide a large amount of rainfall in the early stages of the northwest region and restore the water system in the northwest, then the subsequent maintenance costs will be much smaller.
The second is the technical issue. In order to solve the problem of high cost and difficulty in achieving the effect of traditional artificial rainfall, Academician Zhao Yi proposed a new solution. Let him explain it to you in detail later.
Finally, there is the broader climate issue brought about by climate change in the Northwest. We look at it from two perspectives. The first is from a historical perspective.
Historically, the land in the northwest was not as desolate as it is today, and many areas were areas with flourishing water and grass. This is why our first goal is to restore the water volume of Lop Nur during the Qin and Han Dynasties.
Because we can find the answer from history, we are relatively sure that this will not have a very bad impact.
Our second goal is to restore the water area of Lop Nur to its state four thousand years ago, with the lake area reaching 26,000 square kilometers. We have certain estimates of the impact of this.
As for the larger goal, it is to completely change the climate environment of the Tarim Basin and transform the desert into grassland, farmland and forest. Since there is no historical basis in this regard, we are not sure what changes will be brought about at present.
Therefore, we need to establish a meteorological simulation system to simulate and deduce changes in various meteorological factors in order to obtain a relatively credible conclusion. "
The leader of the Ministry of Water Resources just spoke in a relatively general way. This time he stated the three goals or three-stage goals that he had set, which shocked the attendees.
The first two are easy to say. Although it is still very difficult to implement with the current technology and cost consumption, it is not impossible to achieve as long as you are willing to invest.
But what they didn't expect was that they actually wanted to turn the Tarim Basin into forests, grasslands and farmland. This idea sounded like a fantasy to those who didn't know the inside story.
The Tarim Basin covers an area of 400,000 square kilometers. Currently, only a few residents live in the water sources under various mountains, relying on water sources left by melting snow in the mountains to survive.
Located in the Tarim Basin is the Taklimakan Desert, which covers an area of 330,000 square kilometers. It is the largest and most hostile desert in my country and is known as the Sea of Death.
Not to mention whether changing the overall climate of the Tarim Basin will bring unfavorable changes to the climate of other regions, at least this idea is whimsical, and they really can't imagine how to do this.
After the leader of the Ministry of Water Resources finished speaking, Zhao Yi took the microphone and said: "I will answer some questions. Although the leader just mentioned the three-stage goals, I personally prefer to directly achieve the third goal."
Zhao Yi ignored the reaction at the scene, because once his words came out, they would definitely cause a bigger discussion. The leader of the Ministry of Water Resources just made an assumption, but he directly locked the target.
He continued: "I have certain reasons for doing this. The first one is how to make high-altitude water vapor fall down on a large scale in Xinjiang. I already have a relatively good solution in hand.
The method is still to use artificial rainfall, but the means of rainfall are still different. The traditional launch of dry ice rockets is definitely not feasible, and the cost is also very high. This cannot be a drag on the economic development of the entire country.
But if we have a substance that has strong adsorption power and is lighter than air, and then release these substances on a large scale in the Tianshan Mountains, let them automatically float into high-level water vapor.
This saves the huge cost problem of launching rockets, and at the same time solves the problem of conditions for high-altitude water vapor to condense into water droplets, which has great advantages over traditional dry ice rainfall.
The only question now is whether this substance exists, whether it is cheap to produce, and whether it will cause greater meteorological problems if it stays at high altitudes for a long time.
I can give a very definite answer here, that is, there is this kind of material, which I call hydrogel. It is a special porous lightweight material produced using ordinary water as raw material. It has a density of L and is much lighter than air. .
Even if there is no strong wind, it is enough for the hydrogel particles to float into high-altitude water vapor. What's more, Xinjiang has a high temperature and is in a high-pressure zone, with strong updrafts, making it easier to float to high altitudes.
As for the cost issue, I made a preliminary calculation and found that the cost per ton of hydrogel particles is about 10 yuan, which is still acceptable.
According to the requirements of the third goal, if a stable water supply is formed in the Tarim Basin, not counting the decline in local evaporation water, approximately 1.3 trillion tons of rainfall will be needed every year.
Since the adsorption force of hydrogel is very strong, it can reach 1,000 times its own weight. In other words, the total weight of this kind of hydrogel particles is required to be more than 1.3 billion tons every year. In actual use, it may require about 1.5 billion tons. The cost is approximately more than 15 billion yuan.
This cost is much cheaper than sending water from east to west. It is precisely because of the existence of this substance that I set the goal at the third stage, because we have the conditions for execution.
Even if the use efficiency is insufficient during the actual implementation, resulting in not all hydrogels playing a role, the total investment will not exceed 20 billion yuan.
Moreover, hydrogel has a characteristic, that is, in a saturated state, it only takes half a day at most to self-degrade and turn into water, while in an unsaturated state, it takes one day to self-degrade.
The actual situation should be somewhere between the two. It depends on the water content of the hydrogel, and the value will change moderately.
With this characteristic, I believe the hydrogel will not float too far and cause climate changes on a larger scale. "
When everyone at the scene heard what he said about hydrogel, they felt that it was created for high-altitude artificial rainfall. Is it a coincidence or is his research and development strength really terrible? (End of chapter)
