If the biological soil crust was Jiagu's first surprise to Academician Yuan and others, then the water outlet in the core area gave him an even greater surprise.

The "well" drilled by Professor Chen and others is no longer visible, and is replaced by a small lake.

When the pristine blue sky is projected on the water, the rippling blue is enough to make people feel intoxicated. The waves spread out, so that the desert is no longer desolate, but full of jumping and soft dynamics......

Academician Yuan's eyes widened: "This is what you are fighting...... Well?"

Chen Jianzhang spread his hands: "Yes, who would have thought of it?"

The pressure of fresh water in the ground gushed out uncontrollably, and it slowly formed a small lake, and it was still expanding. Water is the lifeblood of the desert. With water, the surrounding ecology has been altered.

Academician Yuan followed Chen Jianzhang with great interest to visit the environment that has changed due to the lake.

Clusters of sandy plants such as sand mustard and artemisia annua come in a variety of colors, which not only hold the dunes in place, but also make the desert look bright and lively.

Augenous are basically some "short-lived plants" in the desert that will germinate, grow, flower, and bear fruit in a highly concentrated time process. Their seeds are mostly dormant and do not germinate until the moisture content in the soil reaches the standard.

After the formation of the lake, between the yellow sand and thick soil, it was rejuvenated overnight, the green grass was scattered, and then the flowers bloomed.

And because the "well water" gushes non-stop, in order not to waste water resources, the water search team planted a lot of desert plants in the surrounding area, so "the sun and the moon change the sky".

The camel thorns, which have leathery leaves, jagged branches, and extremely strong root penetration, are avoided by many herbivores, but they are the favorite of camels;

It is a plant loved by herdsmen, and the root system is not large and outstanding, but it has a fiber sheath, which can prevent the root tip from being fumigated by hot gas or scratched by quicksand;

The leaves degenerate into scaly red willows, and whenever the flowers bloom, the small pale red flowers stain the earth, which will become a beautiful scenery in the desert;

The strong and standing desert guardian S. amon, with a well-developed canopy and a strong root system, can resist strong winds without falling, and play a role in reducing the wind speed on the ground and fixing sand, and parasitic plants such as Cistanche, a precious drug, also parasitize the growth of the rhizomes of H. ammodendron......

It can be seen that all these desert plants, their attitude towards water is open-source and thrifty, like thrifty housekeeping, and they will not waste it easily, either painstakingly reducing the surface area of the leaves or keratinizing the surface to reduce transpiration, or the roots are deeply rooted and actively looking for new water sources......

And in addition to these desert plants, there are also some uninvited "elves".

From time to time, geese, cranes and wild ducks fly in to spend the summer, and the wild ducks, in particular, are the most daring, and greet visitors with their crisp and loud calls when people approach.

And some big guys.

"Is that a Bactrian camel?" Academician Yuan said with a smile as he looked at a group of leisurely figures in the distance.

Chen Jianzhang also smiled: "It should be a group of semi-wild camels, I heard that they often come to report." ”

With enough research into the desert, it's hard not to like a creature like a camel.

The Bactrian camel was once a moving bridge between Eastern and Western civilizations. They are faithful to the death. Whenever a sandstorm hits, the camel will use its hooves and mouth to arch a big pit for the owner to dodge, and it will lie on its side on the edge of the pit to block the yellow sand, and when the camel driver is cut out of food and hungry and thirsty, he will cut a small hole in the camel's body to suck some blood to continue his life, and the camel will endure the pain and cooperate with the owner......

Today, when camels are gone, camels in a semi-wild state have actually become an important part of the Gobi desert ecosystem. Many of the grass seeds on the Gobi have hard shells, and the seeds are easier to germinate after the process of digestion and excretion by camels. In addition, the camel is used to walking around while grazing, so it is also a "seeder" of nature.

After the surrounding ecology improved, these camels were also attracted to come and leisurely forage here. The two of them looked at this rather spiritual animal, and saw that when they ate grass, they never ate a plant, but ate as they walked, and tasted each one lightly, so as to leave the plant a full chance to regenerate.

Academician Yuan said with a smile: "In the desert, there is really a place with water, which is heaven, and life comes from it. ”

Chen Jianzhang nodded and said: "This also gives us a hint, no matter how the desert is developed, we must set aside an area to build an ecological reserve, so that these creatures from afar can better inhabit ......."

After about a turn, Academician Yuan said: "The ecological recovery speed here has greatly exceeded my expectations!"

Chen Jianzhang agreed: "But no? We all know that what plants grow in a place is not determined by people, but by natural factors such as soil, water, and climate in the area. Originally, I thought that even if fresh water was struck, it would at most revert to a grassland form due to strong evaporation. But the situation seems to have been unexpected. ”

"You may not believe it, since the formation of the lake, the evaporation is high, but at night the temperature drops quickly, and the water vapor is condensed into mist or dew into the sand, and we estimate that the total amount of condensate in a year is equivalent to about 400 millimeters of average annual precipitation here, which is the precipitation line for farming. ”

Academician Yuan was taken aback: "Are you sure?"

Chen Jianzhang said solemnly: "It's like a fake!"

Neither of them knew that it was also someone's handiwork.

"Five buckets of clouds and rain showers triggered, main water system, range: 1,000 kilometers in radius. Effect: Gather clouds and dissolve rain. It can make the water airflow and turn wind and clouds into rain. ”

The evaporation of the desert is large, and the wood is related, and the "Five Bucket Cloud Rain Array" is like a transparent barrier over the desert, although there is no direct rainfall, but it is returned through the clouds and clouds at night to maximize the preservation of water resources.

Although the two did not know this, it did not prevent the two from making judgments.

"In other words, there is potential here to become another loop?" Academician Yuan incredulated.

From Helan Mountain to the foot of Yin Mountain, the Yellow River is like a single-handed, courageous pioneer, creating a fertile Hetao Plain in the hinterland of deserts and grasslands. It is precisely its appearance that has allowed the boundary between agriculture and animal husbandry to break through more than 400 kilometers to the north, breaking the established rule of "grasslands and deserts below the 400 mm isoprecipitation line", and a suitable cultivated land for settlement has appeared outside the closed blockade.

Chen Jianzhang said: "A river can change a certain set of rules, and if it is a big lake, it is not strange to change some kind of rules, right?"

"Great Lake?" Academician Yuan keenly sensed that there was something in the words.

Chen Jianzhang asked without answering: "Do you know where the water we pump comes from?"

"Oh, I'd like to hear about it......"
