Chapter 1147 overturns the consensus of the world!
For Chang Haonan, this number is indeed conservative.
According to the comparison of remote sensing and Mongolian statistics, the area of sandy and semi-sandy land that has the potential to be transformed in Wumeng City in the east alone should be around 60-80 million acres——
Because the huge amount of degraded land area is not a long-standing thing in the statistical list, local governments have no incentive to make false reports on this kind of data.
The results are basically credible.
Moreover, although Chang Haonan had never been exposed to any agricultural projects in his previous life, he also knew that Mongolia Province had actually been developed into a top agricultural production area.
Thanks to the relatively flat terrain, it is still the kind of production area that does not require intensive farming.
The reason why I fold it in half as soon as I open my mouth is mainly because of the psychological endurance of the leaders.
Otherwise, when you came up and said you wanted to build nearly 100 million acres of new farmland, it was really an exaggeration.
But...
It can only be said that Chang Haonan's considerations are indeed a bit humane.
But not much.
What is the concept of 40 million acres?
According to statistics in 1996, the total cultivated land area in China was only a little over 1.9 billion acres.
In 2003, the red line for cultivated land was not proposed yet. Considering the large amount of occupation over the years, the actual optimistic estimate is only about 1.8 billion acres.
This is equivalent to conjuring up 2.2% of the existing cultivated land area out of thin air.
If you put it in the general field, a mere 2% increase in production capacity is really not worth mentioning.
But this is agriculture.
The lifeline industry in the physical sense.
If necessary agricultural products are short of 2%, then the market price will definitely not only increase by 2% without considering policy allocation.
Instead, it will rise until 2% of people starve to death.
Therefore, after hearing this number, he still heard a few faint inhaling sounds coming from around him.
Li Zhongyi, who had been sitting on the edge just now and muttered about making a fortune, suddenly raised his head and leaned back tactically at the same time.
Looking at Chang Haonan, one sentence can clearly be read:
"Little ancestor, what kind of cruel work are you going to do?"
Seeing that the atmosphere was a bit cold, Chang Haonan finally realized that perhaps transforming 40 million acres of cultivated land was still a bit beyond imagination for China at the moment.
But he was also very unjust.
Obviously it was the leader who insisted on asking "without considering the capital investment and other costs" just now.
Then you should expect to get a very exaggerated number...
Actually, this is Chang Haonan's own preconceptions.
At the beginning of the 21st century, both internationally and domestically, there was overwhelming publicity that global warming would lead to land degradation and reduced agricultural production, etc., which led to everyone generally having pessimistic expectations about the future.
Leaders are also human beings and will also be affected by this kind of public opinion.
But in fact, after more than ten years, everyone discovered that this matter also depends on the situation.
For Western Europe and the United States, the above conclusion is indeed correct.
But for Central Asia, East Asia and North Asia, the northward movement of precipitation and isotherms is beneficial to agricultural production.
Therefore, there is indeed a huge difference in concepts between Chang Haonan, who has experienced these things, and people who were "born" in this era.
Fortunately, he also left a hook before, so he can continue to make amends now:
“Of course, this is without considering other external restrictions... Such a large area of soil If the overall improvement project is really implemented, in addition to the visible economic and social benefits, it will even have an impact on the ecological environment of the entire Northeast Asia region, no less than a century-old project like the South-to-North Water Diversion Project that mobilizes national efforts."
“Therefore, even if it is only the first phase of the project, it needs to be further implemented in stages. Considering that this is still a new technology, especially the effect under long wheelbase and large area conditions is lacking data, so first of all, we are Prepare to use 3-5 years to conduct a medium-scale experiment covering an area of 500,000 to 1 million acres, and then..."
However, before Chang Haonan could finish the entire three-step plan, another The leader raised his hand and interrupted him:
"We will talk about these processes in detail later... If you really think that eastern Mongolia alone has the potential to transform tens of millions of acres of land, then no matter how small the scale of the first step is, when planning It must be carried out in accordance with the standards of the Century Project.”
“So, there are several questions that you need to consider carefully.”
Although the answers were indeed given by Chang Haonan at the beginning. He was shocked, but after all, he was a senior leader who was used to seeing the world, and he quickly regained his rationality.
“Even the east, which you just mentioned, has relatively good climate conditions, is still a semi-arid area, and the surface water systems that agriculture in Mongolia Province can rely on are mainly the Hetao Basin of the Yellow River and the Xiliao River, but These two water systems are also the lifeblood of the industrial and mining industries in the four cities of Hubei, Baotou, Echi and Chi, and it is impossible for them to be used entirely for agricultural production.”
Although there was no map in the entire conference room, he still stretched out his hand as he spoke. He took action and pointed at several locations in the air in front of him.
Almost exactly corresponds to the places just mentioned.
Obviously he knows the actual situation very well:
“If agricultural production relies on groundwater for a long time, it will undoubtedly lead to over-exploitation, which is not a long-term solution.”
“Here In this case, if the decision-makers really pass a mid- to long-term plan for 40 million acres, or even a larger scale, how are you going to solve the water conflict? "
This question is a sharp one.
It is also the link that seems to have the biggest loopholes in the entire plan.
Although eastern Wumeng City is part of Northeast China at the zoning level, geographically speaking, only part of the land east of the Greater Khingan Mountains is actually an extension of the Songnen Plain.
Of course, it has already become a major agricultural production area.
The three sandy lands that Chang Haonan mentioned before do not actually benefit from the environmental dividends of the Northeast region.
At the beginning of the 21st century, soil erosion is at its most serious stage.
The water balance in Mongolia, and indeed the entire north, is already at a precarious level.
The Yellow River even has an outrageous record of having zero runoff into the sea for several consecutive years.
In this case, let alone 40 million acres, even 4 million acres may be the straw that breaks the camel's back.
Sitting next to him, Zhuang Bingchang, who had not spoken since he introduced his work situation, changed his face slightly.
He has worked in the Northeast and Northwest regions for a long time, and he knows very well that all the situations mentioned by the other party actually exist. In fact, Chang Haonan had never disclosed this figure of 40 million acres to him before...
However, the former showed a slightly happy expression -
Asking such a specific question showed that the other party was already interested.
It would be really troublesome if others kept discussing some floating topics.
Therefore, he immediately replied:
"From the perspective of treating symptoms, a number of water conservancy facilities can be built in this area."
"As you just said, the Xiliao River can play a role in irrigating the eastern part of the Horqin Sandy Land and Hunshandake Sandy Land. It has a supporting role, but it suffers from insufficient flow. Therefore, we can consider drawing on the successful experience of the South-to-North Water Diversion Project to divert water from the Chuoer River to the Xiliao River, supply water to cities and industrial parks along the route, and combine irrigation with power generation and other comprehensive utilization.”
< br>When Chang Haonan said this, he only heard a burst of laughter from around him.
“Nothing.”
Someone soon explained:
"Thank you, Academician Chang, for your best wishes for the South-to-North Water Diversion Project..."
Just kidding.
Although the first phase of the South-to-North Water Diversion Project has just started, there are still 300-400 kilometers of water conservancy projects even in the inspection stage before the project is approved.
Compared with the earth-shattering pie before, this proposal of "introducing Chuo to Ji Liao" seems not too out of the ordinary.
“You just said that this is a temporary solution...”
The leader who asked the question at the beginning took the lead in calming down the somewhat loose atmosphere:
“Then listen to this...Academician Chang, do you still have a way to cure the root cause?”
This time, Chang Haonan He shook his head very simply:
"With today's human technological level, it is still a bit too difficult to completely overcome the laws of nature..."
Some eyes revealed a few words. Very sorry.
If the climate can be fundamentally improved, it will definitely be a sure win in long-term international competition.
However, Chang Haonan has not finished what he said:
“So, it is not me who can cure the root cause, but the environment itself.”
The effort of just one sentence , which caused many people to experience the ups and downs of their mentality.
“The environment itself?”
A leader from the land and resources system suddenly became interested:
“Academician Chang, you won’t also support the plan to dig a hole in the Yanshan Mountains to allow the warm and humid air from the Bohai Sea to blow into Inner Mongolia, right? "
Chang Haonan: "..."
Zhuang Bingchang: "..."
Other leaders: "..."
Chang Haonan himself didn't even know that anyone else had proposed such an idea.
It sounds similar to digging up the Himalayas and letting the Indian Ocean air flow into Xinjiang Province...
He quickly shook his head:
“It doesn’t have to be so troublesome. ..."
"In fact, as long as the current trend continues, in more than ten years, with global climate warming, the hydrothermal conditions and environmental carrying capacity of central and western my country will naturally decline. It will improve..."
"!!!"
The dozens of people in the conference room almost all focused their attention on Chang Haonan again -
The 40 million acres of cultivated land just now was only in quantity. It's exaggerated on a level.
After all, China has never stopped researching soil consolidation and sand control technology since the founding of the People’s Republic of China.
I just never thought it could have such a good effect in the past.
However as mentioned before.
This conclusion was placed in 2004, but its direction is completely different from the current commonly defined "common sense"!
“Can you tell me the reason?”
Someone soon asked:
“Is it calculation, or...”
"The evolution of the earth's climate is too complex, and there is almost no 100% reliable theory... Calculation alone will definitely not work."
Chang Haonan replied:
"My judgment is based on two The reasons are, first, the analysis of the laws of soil stratigraphy and historical climatology. The increase in earth temperature is not a bad thing for a continental country like my country..."
"The second is that our country has systematically implemented continuous It lasted for more than 40 years and is the largest surface greening project in human history. Although manpower alone is not enough to reverse nature, it has the foundation to undertake the improvement of climate conditions. This is an advantage that no other country has. It means that we cannot copy the research results of foreign researchers in the field of ecological environment..."
"Academician Chang, please wait..."
The leader who just asked the question took a deep breath and did not let Chang Haonan continue.
I must admit that what the latter said just now is indeed very nice.
Especially the second point is almost aimed at the preferences of his generation.
But his reason told him that the more pleasant the words are, the more attention should be paid to judging their accuracy.
Moreover, Chang Haonan is not a geophysics expert.
Compared with the rich experimental data and calculation process he presented when introducing soil stabilization and sand control technology, the explanation in these few sentences is a bit too thin.
As a scholar, Chang Haonan can give speculations that are consistent with logic and existing theories based on his own judgment.
But as a decision-maker, he has to ensure that he listens and understands.
At least you need to find a professional to discuss it.
“The matter is very important. We may have to confirm the correctness of this conclusion again.”
"So I propose to adjourn the meeting temporarily and continue discussing this issue at an opportunity..."
