Desert greening can restore the country s land, but why is Japan desperately trying to prevent deser

The Tottori sand dunes of Tottori Prefecture are known as the only desert in Japan, and as urbanization continues to grow, large areas of sand have been transformed, leaving only this small area of desertification along the coast. Due to the abundant rainfall in Japan, there has been vegetation growing around, and this small area is also disappearing, so in order to let the Japanese people see the desert in the country and maintain the local economic development, the desert greening can only be artificially prevented.

In fact, in addition to the Tottori sand dunes in Tottori Prefecture, there is another desert in Japan, which is the Saru-no-Mori Desert in Aomori Prefecture, which has been used by the Japanese military as research and development land for a long time, and has been under military control for a long time, so ordinary people cannot get close to this place, so the Tottori sand dunes in Tottori Prefecture are particularly important, after all, Japan wants to keep this only desert that can be viewed.

In Tottori Prefecture, it is the hometown of Aoyama Gomasa, the author of Japan's own anime detective Conan, and the main economy is tourism, and most of the people who come here are there to see the desert, because this is the only place in Japan where you can see the desert. More than 2 million tourists visit the area every year, so in order to maintain the lifeblood of the local economy, Japan** does not hesitate to spend a lot of money to clean up the vegetation that grows around the desert and prevent these vegetation from reducing the area of sand dunes.

If you think it's just a whim in Japan, you're wrong, but this project has been going on intermittently for 30 years, which is super perseverance.

Other countries are trying to reduce desertification, but at a time when desertification control has become a common problem that the world needs to solve, Japan has to do the opposite and spend money to expand the sand dunes. But it's understandable why, as it's the only place in Japan where you can see the desert.

In Japan, desert is a scarce item and has become the most special and precious item in Japan.

In order to allow the Japanese people to have a glimpse of the desert in their own country, and at the same time, to maintain the lifeblood of the local economy. As early as the end of the last century, Japan spent a lot of money to clean up the vegetation growing around the desert, and deliberately expanded the area of sand dunes.

Because their land area is not large, the land area to be used for economic development is not enough, and there is still a place to plant greening, and in the case of not satisfying economic development, greening has become a muse.

Japan is an island country surrounded by the sea, and it is known for its small land area, but deserts are extremely rare in Japan, with only two small patches of the Saru-no-Mori Desert in Aomori Prefecture and the Tottori Sand Dunes in Tottori Prefecture. Among them, the Saru-no-Forest Desert in Aomori Prefecture was requisitioned by the Japanese military as a military equipment research and development test site, and ordinary people did not enter; The remaining Tottori sand dunes are the only desert in Japan, so how can Japan let them be green?

In addition to the desert, Tottori Prefecture is also the hometown of Aoyama Gomasa, the author of Detective Conan, and because of this, the local tourism industry is very developed, with more than 2 million tourists visiting every year, which is one of the important economic lifelines of Japan. What's more, the airport was named Tottori Dune Conan International Airport, and it is not difficult to see that the contribution of foreign economy to Tottori Prefecture's economy can be seen.

In recent years, the urbanization of Tottori Prefecture has led to the transformation of sandy land, and the area of sandy land has been gradually reduced, leaving only a small area near the beach along the coast. However, abundant precipitation is a good thing, but when it happens in Japan, there is a kind of dumb people who eat Coptis chinensis and have an indescribable rush. Faced with such a dire situation, Japan had to send people to clear the greenery every day.

Desertification became widespread after the catastrophe caused by the severe drought in the Sahara in the 60s of the last century. Now the control of desertification has become a global initiative and is concerned by all countries in the world. However, Japan has done the opposite, and has spent a lot of manpower to prevent desert greening, and the reason for this is to protect the country's only desert and protect the country's important economic lifeline.

The reason why Japan wants to protect this desert is because this desert is the only desert in their country, and they are afraid of desert degradation

Their way of thinking is really strange as the Japanese race, and it's very different from us, maybe people have their own ideas.

I am afraid that desert greening should not, desert greening is good for the environment and the earth.

No, an island country like Japan is easy to disappear, so it shouldn't be self-defeating.

Hahahaha, Japanese people think differently than we do, of course, they should have their own reasons.

Isn't greening good, why remove the plants, ask the gods to explain.

The Tottori sand dunes in Tottori Prefecture, Japan, send people to clear the plants every day, they are afraid of the desert "greening, this problem is really not very clear, I don't particularly understand this problem, ** and other gods".

What do you think of the Nature report's claim that greening deserts in northwest China could lead to water depletion?

to stop the expansion of the desert, ** the desert and the Jing Wei are distinct, the vast desert and the "tree" line apart. But in fact, the map is not a tree, or even vegetation, it is called "grass square", which is a very effective means of preventing the expansion of desert in the desert area of China. The author preconceived to tell you that a large area of China is planted with trees, trees, trees, trees, and all the belts are aimed at planting trees, but the accompanying picture is a grass square.

The same as Fu Songbin of Nanjing University: It is too early to say that it has solved desertification; Ecological restoration takes a long period of time, even more than 100 years in scientific research, which is correct for the words of the two teachers, and each has solid research support. But the author puts them together in order to use the latter's words to disprove the former's views.

It seems to be a negation between scientists, but it is actually what the author wants to express.

86% of the population lives in the eastern region, and the western part is too desolate and uninhabited. What dangerous tests are the country conducting, atomic bombs, hydrogen bombs, neutron bombs, missiles, etc. are all in the northwest, in other words, the country owes the northwest region. Why, Russia straddles the Eurasian continent, almost the entire territory is forested, and timber is sold all day long.

In itself, almost the entire ecological environment is fragile, and if you don't pay attention to it, it will become more and more serious. Think about how strong the country's greening projects around Beijing are! It turns out that deserts can be managed.

In the northwest region, there are few people, no money, and no energy to control the desert, and the long-term population loss is too fast to move to the eastern region. If the state speculates on the desert like real estate, it is estimated that the speed will be faster. Sell the desert to a private private owner for 100 years, and it is estimated that someone will actually go and plant trees.

It is necessary to turn desertification prevention and control into a project of the century, and set up a special force to plant trees and protect forests all year round, just like the army.

It's not that I don't want to, it's that the technical and financial resources can't .........There is no water more than 100 meters underground in desertified areas! Water it and evaporate ...... immediatelyNo plant can survive ......Watering the plants continues to evaporate, and evaporates the deeper areas of the groundwater .........At present, the technology has some ground cover plants, which are still being explored, and with commercial operations, it will be improved in the future.

Troll, you ask a question, can you check it first, the country has been greening, in the control of desertification, but there is a sequence and time, how can it be possible to put all the energy into it at once.

The amount of precipitation in the desert is so small in a year that the green vegetation cannot survive.

In places where the amount of precipitation is okay, greening can be done, and where there is little precipitation and poor groundwater, greening requires the consumption of a large amount of water resources, which will lead to further deterioration of groundwater resources. Similar to the Kubuqi Desert and the Mu Us Suli Desert, there is still greenery, the precipitation is relatively high, and the greening is not bad. Greening around the Tengger Desert can also be used to prevent the desert from expanding further.

Greening in the heart of the desert is too costly.

The roots of trees can be very deep, while cacti have shallow roots, and their ability to grasp soil is very different from that of trees.

There are quite drought-tolerant varieties of trees, which are native to the desert, to the edge of the desert, and to the beach.

Unlike the stems, the roots of cacti are non-fleshy, and the root groups are shallow (15 30 cm), even in the dendritic cactus, the root groups are mainly distributed within 30 cm below the ground, and some cacti that grow in the badlands have abnormally thick storage roots. The cactus root system covers a very large area and is used to absorb the most rainwater during heavy rains. When the soil is dry, the fine lateral roots usually die, while the larger roots turn to be covered with cork cork (cortex).

The root protoplasm under the main root cortex grows rapidly when the soil is re-moistened, increasing the absorption capacity of water and minerals within a few days. The mesh on the leaf-like stem of the flat cactus is easy to grow roots and reproduce when it touches the ground.

Trees protect against disasters such as sandstorms and desertification.

It is the raising of chickens after the greening of the desert, not the raising of chickens that can green the desert.

The Kubuqi Desert Photovoltaic Power Station has a total of 1.1 million photovoltaic panels, which can not only generate electricity, but also effectively block wind and sand, plant Chinese herbs and other plants under the photovoltaic panels, fix sand, reduce water evaporation, and drive local farmers out of poverty.

The alfalfa then planted is mainly used as feed for chickens and geese.

Because of the characteristics of the digestive tract of chickens, the organic matter content in the excluded manure and urine mixture is relatively high, and the long-term accumulation of chicken manure can change the soil structure of the desert, improve the organic matter, and gradually colonize plants, thereby greening the desert.

Raising chickens improves soil fertility and can eat pests. can promote plant growth.

As far as I know, the monthly salary of the workers in the sand control forest farm in the Baijitan Reserve is 2000-3000
