The demonstration team of the two desert reservoir projects spoke highly of the Jiagu desert wind farm.

In addition to the economic development brought about by the development of related industries driven by the construction of wind farms, the wind farm itself alone has an average annual net creation of social wealth of tens of millions of yuan.

But for Jiagu's other initiative, the million-acre "oasis" that revolves around the treatment and development of reservoir points, it has mixed reviews.

Zhu Zhenfu, an expert in the study of ecological environment and resources in Northwest China, has been involved in the management of the Kubuqi Desert, and in his opinion, Jiagu's development of the Tengger and Badain Jaran deserts is unreasonable.

At the meeting, he questioned Jiagu's ambitions: "In my experience, only human-caused desertification areas, such as the Kubuqi Desert, are worthy of ecological restoration. In the history of climate change, desertification in Kubuqi is only a flash in the pan caused by human factors. As long as it is not overdeveloped, the Kubuqi Desert will slowly recover to grassland from a long-term historical perspective. ”

"But these two deserts are different, they are part of the ecosystem, like a humidifier, without the desert, how can the water cycle be maintained?"

"Therefore, it is enough to construct a 'Great Wall' of greening around the two desert reservoirs, and use green belts to lock the edge of the desert to protect the reservoir from wind and sand. Instead of directly turning the desert into an oasis or even developing agricultural ......"

In fact, Zhu Zhenfu is very skeptical, in the desert, even if there is water, can it really become a paradise for agriculture? Or even if there is a temporary effect, how long can it last?

Don't cite Israel as an example, in fact, Israel's desert agriculture is not foolproof.

New red flags of desertification are emerging in Israel, the use of treated sewage for agricultural irrigation is expanding, but the treated sewage is not desalination and is in danger of widespread salinization, and excessive road construction and road use in arid and ultra-arid areas has led to a reduction in vegetation and soil degradation in the vicinity. These signals have already begun to receive the attention of relevant experts.

There are also many experts who support the development of the desert in Jiagu.

But Wei Ming is not a vegetarian either, in fact, in the past year, he has heard a lot of doubts about Jiagu's development of the two major deserts of the Al-Tan League.

"You know what? The Two Desert Reservoir Project reminds me of the Central Valley Project and the California Water Conservancy Project in the United States. ”

"Historically, much of central and southern California has suffered from severe water scarcity, with the exception of a very narrow area close to the coast, which has been a completely desert climate overall, with only a handful of periods of rain throughout the year. In these areas, without artificial irrigation, all crops will be lost. In fact, as far as I know, almost all of the areas in central and southern California that are not covered by artificial irrigation are desertified. ”

Isn't that something like local?

"But the Central Valley Project and the California Water Project, two major water projects, have changed everything. The former transformed the San Joaquin Valley from a barren desert into one of the nation's most important agricultural centers, a marvelous project that has even been called 'the most significant man-made transformation on the surface', while the latter made Los Angeles and other places east of it, including Riverside and Ontario, habitable, and the second largest metropolis in the United States. ”

"Today, California has the largest population of any state in the United States, and has become a sunny land for agricultural production, and California's fruits, agricultural products and non-staple foods are the most abundant and cheapest in the United States. ”

"With the two desert reservoirs, who dares to say that the Alxa League, which has two deserts, can't become our California?"

Speaking of this, Wei Ming glanced at Zhu Zhenfu and added lightly: "What's more, our management and development of the desert has changed the climate ...... in local areas."

"It's impossible!" Zhu Zhenfu blurted out and retorted.

"Even in the Kubuqi Desert, which is close to the waters of the Yellow River, the evaporated water vapor is easily carried downwind, so the evaporation of the Yellow River does not contribute much to the rainfall in the region......

In short, in the northwest, local evapotranspiration only exacerbates water depletion and has little effect on precipitation, which only comes from the Pacific Ocean or Russia;

Facing the suspicious eyes of the experts, Wei Ming was not in a hurry, spread his hands and smiled: "Seeing is believing......"

......

Stationed in the "oasis" developed by Jiagu governance, Zhu Zhenfu and others quickly "saw is believing".

That night, the thick fog rose at some point, rolled in, and spread throughout the oasis, literally reaching out of sight.

The next morning, a large amount of fog was still visible, and it was not until the sun came out that it slowly dissipated.

But looking around the oasis, whether it is pasture, or the leaves of sand willow and saxon, it is like a spider's web full of water droplets after rain, and when the fog is raised, the humid water vapor in the air condenses into water droplets on the stems and leaves, and flows into the sand, and the water is "captured" by them.

Although there is no precipitation, plants that are moistened by fog water are more vigorous in the sun.

Zhu Zhenfu couldn't hide his surprise and asked Wei Ming: "This kind of foggy day, often appears?"

Wei Ming shook his head: "Not often, just come once every three or five times." ”

Zhu Zhenfu......

Feelings are "often" in your heart, right?

Zhu Zhenfu still couldn't believe it, but ......

A few days later, sure enough, the fog arrived as scheduled, and the dew formed by the thick wet fog fell in the form of a faint powder.

A few more days, this time it was no longer a mist, and the rain was falling suddenly, and he seemed to hear the cheers of the plants as they absorbed the water.

Wei Ming added: "Oh, by the way, there is no fog when it rains!"

The experts ...... , who doesn't know!

The next day, Zhu Zhenfu fell into deep confusion.

Such a scene reminded him of the Lima and Atacama deserts. The former is the world's famous "city without rain", with little rain all year round, but in winter it is thick and heavy fog, and the air is even filled with small suspended water droplets; the latter is the world's "dry pole", but in the coastal area of the desert, there is often a layer of fog.

However...... "the environment on both sides is also different!"

Shouldn't it be that the transpiration of water is strong and the water vapor goes away with the wind? Why is it that the hotter it is, the more intense the evaporation, the thicker the fog and water? This simply subverted his cognition.

He looked up at the sky: "This climate change is not scientific, is it possible that there is a protective shield in the sky?"

He didn't know that this casual remark was just close to the truth.

Isn't there an invisible protective shield in the sky, "five buckets"? After the evaporated water vapor is intercepted, it will cool and condense to form a mist when it reaches a certain concentration, and float to the desert. With a large amount of water mist, even without precipitation, life in the desert can survive.

Wei Ming shrugged: "I don't know if it's scientific, but I know that with such a changed climate, the development of desert agriculture is simply promising!"

Looking at Wei Ming with a smug face, Rao is Zhu Zhenfu also felt that what he said was right......

Just as the experts were conducting "scientific" research on climate change, Wei Ming received news that Xie Kaiji of Jiagu Agriculture and Li Dongliang of Jiagu Agriculture and Animal Husbandry had gathered in the Tengger Desert.

He couldn't help muttering, the two bigwigs are here, do you have any big plans?
