Why does Beidacang want to return farmland to waste ?

The reason why "Beidacang" wants to return farmland to "famine" is mainly due to the following reasons:

One is because soil erosion is staggering. We know that the average annual precipitation in the Northeast is not much, and it is generally concentrated in summer, and in most cases it is heavy rainfall. Due to the "Great Northern Wilderness" becoming the "Great Northern Warehouse", a large number of vegetation has been destroyed, and once it encounters heavy rainfall, it will concentrate the runoff, and the scouring force will be very strong, and the local soil will also suffer from water erosion.

Similarly, in the spring, when the snow melts, the snowmelt runoff is washed away when the black soil thaws. In fact, this freeze-thaw erosion phenomenon is very serious, and its erosion rate is no less than that of soil erosion caused by heavy rainfall. In fact, if you have been to the Northeast region, you will find that in the black soil area, where soil erosion is very serious, you can even see a scene similar to the Loess Plateau, where a large number of fertile fields have been washed by the rain and are shattered and devastated.

The second reason is that ecological problems are getting worse. In fact, over the years, the Northeast has been over-exploited, and because of this, the wetlands in the Northeast have been reduced by half. As we all know, wetlands are the "kidneys of the earth", which can purify air and water, and at the same time alleviate drought and flood, and play a vital role in the detoxification and decomposition of waste, as well as the increase and restoration of soil and its fertility.

Once the wetland area is reduced to a certain extent, these effects will also be weakened or even disappear directly, making the climate of Northeast China more fragile. Once the climate is abnormal, the local natural disasters will gradually increase, such as drought, flood and wind disasters, and more importantly, if the climate is abnormal, the local wildlife will also be forced to migrate to other places, and the spring sand weather in the Northeast Plain is increasing year by year. In the long run, the Northeast region may become a source of sandstorms.

It is worth mentioning that soil erosion will also directly cause sediment discharge, silt up rivers, reservoirs and roads, and then cause frequent floods. According to relevant statistics, due to sediment accumulation in the West Liaohe River Basin, as many as 89 water conservancy projects have been scrapped. Not only that, soil erosion will also cause great damage to the black soil, according to Professor Zhou Lianren of Northeast Agricultural University, it will take at least 400 years for the black soil area to form a 1 cm of topsoil, if not protected, at the current rate, it will only take another 50 years for the black soil layer to disappear completely.

In fact, according to the Heilongjiang Water Conservancy Bureau, about 1.4 million acres of land in the province have disappeared due to soil erosion.

It is precisely because of these reasons that the "North Warehouse" has to return farmland to "famine". So, how should the Northeast region return farmland to "famine"? In fact, it is very simple, first of all, we must first return the land by the lake and river; second, do a good job of compensating farmers; Finally, after returning farmland to forest, it is necessary to continue to protect it.

Because at that time, for the sake of people's food production, many trees have been cut down, and the vegetation cannot be well protected.

In the early days, China was short of food, so it was cleared, and now food is no longer so scarce, the early land reclamation is actually overdrawing the life of the local ecosystem, and now the economic development has caught up, and the natural needs are still scarce, and people rely on nature to survive.

The reason why Tohoku is called "Kitakura" is because the land there is fertile, but after years of land reclamation and planting, the fertility of part of the land in "Kitakura" has been over-depleted and has become barren, so it is necessary to return farmland to "barren" to restore soil fertility.

The Great Northern Wilderness is located in the northeast of our country, according to historical records, the Great Northern Wilderness has been a wild land since ancient times, where the weeds are overgrown, the beasts are everywhere, the climate is harsh, full of thorns, for various reasons, the place has never been reclaimed, resulting in a wasteland, and later people responded to the call of the country, began to reclaim the wasteland of the Great Northern Wilderness, and changed the world with their own hands. In order to respond to the concept of peaceful coexistence between nature and human beings, the policy of returning farmland to forests and lakes has also been implemented in the Great Northern Wilderness.

Because of imported grain! So Kitakura was wiped out.

At that time, the state organized a large number of manpower to reclaim the Great Northern Wilderness, why is it now returning farmland to the wilderness.

No, the return of farmland to the land is also carried out under the framework of scientific rationalization, which does not mean that all the cultivated land will be turned into wasteland, so that the previous achievements will be wasted. Beidacang should be returned to farmland in order to effectively protect the environment and truly achieve the harmonious coexistence of man and nature.

The Great Northern Wilderness refers to the Sanjiang Plain north of the Heilongjiang River, and its desolation is caused by local climatic conditions and geological factors. To this end, under the call of the state, local residents and professionals in other regions jointly began to develop the Great Northern Wilderness, which gave a new lease of life to the originally barren land. Especially through people's continuous development and exploration of the Great Northern Wilderness, agriculture and animal husbandry began to develop steadily, and at the same time, with the support of the state, a large number of machines were also invested.

Of course, the transformation of the Great Northern Wilderness into the Great Northern Warehouse is also related to its innate advantages, the Great Northern Wilderness is vast and sparsely populated, and it is almost affected by human activities, and there are very few cases. A large amount of land can be developed and planted to the fullest, so that the local agriculture and animal husbandry can develop rapidly.

The Great Northern Wilderness can become the Great Northern Warehouse is inseparable from the precious black soil and rich water resources, the black soil of the Great Northern Wilderness is not only low in damage rate, but also rich in organic matter and minerals are very fertile. It's just that the local area is in the northern part of our country, and the temperature is relatively low, and the planting of the dealer can only achieve one crop a year. This also ensures that under the long planting cycle, the nutritional content of the harvested grain is higher, which is highly sought after by many consumers.

There is also the Great Northern Wilderness close to the Heilongjiang River and the Songhua River, which makes the water source abundant, and local farmers do not have to worry about irrigation. Coupled with the openness of the terrain, the entire automatic irrigation and automatic harvesting have become advantages, and promote the transformation of the Great Northern Wilderness into the Great Northern Warehouse.

After the Great Northern Wilderness became the Great Northern Warehouse, the local residents tasted the sweetness and began to over-reclaim the land only for immediate interests. In addition to causing serious soil erosion in the black soil, the sand and soil that flowed out of the land caused irreparable damage to the wetland due to the accumulation of surrounding lakes and rivers.

Take the famous Zhalong wetland in Qiqihar as an example, there are a large number of red-crowned cranes and migratory birds living in the wetland. In the past two years, the severity of soil erosion has directly led to a sharp decline in wetland area, which in turn has triggered the occurrence of local floods, which has had a great impact on the local economy and the growth of crops. At present, only by returning farmland to land in Beidacang and at the same time developing the economy, and putting the protection of the natural environment in the first place, can we avoid the further occurrence of the evil consequences of excessive land reclamation.

Objectively speaking, it is from the perspective of long-term development that Beidacang should be returned to farmland, which can lay a good foundation for the future development of Beidacang. According to relevant data, after the frequent floods caused by the over-reclamation of the land in Beidacang, the food output of local residents has been reduced to more than half of the previous one, and nature has sounded the alarm for the locals! Therefore, the return of farmland to the north is a manifestation of conforming to nature, protecting nature and respecting nature, and when the harmonious coexistence of man and nature can be truly achieved, the local grain production can return to normal.

The main purpose is to protect the local ecological environment, and too much cultivated land will lead to a heavier burden on the land, which is not conducive to long-term development and affects the balance of the overall ecosystem.

The reason why farmland should be returned to famine is mainly because the ecological environment has been damaged to a certain extent in the process of reclamation in Beidacang. There are mainly problems such as soil erosion, ecological damage and frequent natural disasters. The surface of the black soil is uneven and becomes pitted.

Now that Beidacang is going to be returned to farmland, will all the previous achievements be wasted? Improve the ecological environment of the "Great Northern Wilderness" and achieve sustainable development, exceptReturning farmland to landforests, restoring vegetation, there is no alternative; At the same time, we are becoming more and more aware of the importance of the ecological environment.

The reasons why the Great Northern Wilderness should be returned to farmland are as follows:

In the early reclamation process of the Great Northern Wilderness, a large number of woodlands, grasslands, etc., were transformed into large-scale standard farmland, and roads, canals and other supporting projects were built. Although this will bring the benefit of harvesting a large amount of food, it will bring the disadvantages of soil erosion. As soil erosion occurs, so do the nutrients in the precious black soil.

That is to say, for decades, the black soil of the Great Northern Wilderness, like a mother's precious milk, has been absorbed for most of it, and the remaining small part can no longer support long-term extensive development.

The development of the Great Northern Wilderness:

The Great Northern Wilderness is a precious piece of black land located in today's Heilongjiang Province. The thickest layer of black soil in the region, with a thickness of more than 1 meter.

These black soils are formed by the nutrients brought by the alluvial flooding of large rivers, plus the growth of plants, the fall of leaves, and the feces of insects, birds, and animals over countless years. This kind of land grows what is planted.

After decades of development, the Great Northern Wilderness has changed greatly, with 35.6 million acres of cultivated land and a population of 10,000 people. Many of these 1.7 million people are now three generations of farming and four generations of farming. The wasteland reclaimed by our ancestors and fathers with hard work and sweat has now become a high-standard farmland and the granary of China, which continuously provides us with valuable food.

Summary. Kiss! I'm glad to answer for you, the Great Northern Wilderness was returned to farmland because the ecological environment was destroyed.

Returning farmland to famine does not mean that not a single crop is planted, but that every inch of land should be used scientifically and rationally. The main reason for returning farmland to famine is that the ecological environment has been destroyed. A few years ago, people were bent on developing the Great Northern Wilderness as soon as possible, thus ignoring ecological and environmental problems.

Wetlands are decreasing, and with them problems such as less humidity, less precipitation, higher temperatures, and homelessness of animals.

Wetlands are decreasing, and with them problems such as less humidity, less precipitation, higher temperatures, and homelessness of animals.

In order to be able to change the ecological environment of the Great Northern Wilderness, the Great Northern Wilderness was stopped, and a variety of policies were implemented to protect the Great Northern Wilderness, such as returning farmland to grassland, forests, and wetlands, and accelerating the construction of the Three-North Shelterbelt. In fact, the development of the Great Northern Wilderness was a last resort, and now it is a wise move to return farmland to the wilderness. No matter how high the economic value created by the Great Northern Wilderness is, it still cannot withstand the adverse effects caused by the destruction of the ecological environment.

lz, you are wrong, your title is reversed, it should be changed to Beidacang The Great Northern Wilderness is located in the Sanjiang Plain and Songnen Plain of Heilongjiang Province in Northeast China, covering an area of 10,000 hectares. Summers are plentiful and grassy grasses are abundant, while winters freeze and the soil accumulates humus. This piece of black soil, which "can be stepped on with one foot", has become China's "king of the soil".

However, due to its location on the frontier, the winter weather is cold and freezing, making it sparsely populated. In particular, the low-lying and poorly drained swamp land is even more barren, known as the "Great Northern Wilderness". Local folk songs sing:

The Great Northern Wilderness, the Great Northern Wilderness, is a rabbit and a wolf, and the weeds are not fed. "In the 60 years since the founding of the People's Republic of China, 140,000 demobilized soldiers, 50,000 college students, and 540,000 urban intellectual youths have ......He has come here to reclaim the wasteland, and integrate his youth, wisdom and life into this wasteland. Their hard work finally turned the Great Northern Wilderness into the Great Northern Warehouse:

Today, it produces more than 20 billion catties of grain every year, making it the largest commercial grain base in China.

In order to feed the 40,000,000 people at that time.

The "Great Northern Wilderness" often referred to refers to the vast barren areas of the Nenjiang River Basin, the Heilongjiang River Basin and the Sanjiang Plain in Heilongjiang Province. More than half a century ago, it was a vast wilderness, sparsely populated, densely forested, swampy, infested with wild beasts in the forest, and hundreds of birds flew at low altitudes. "Beating the leopard and scooping the fish, and the pheasant flying into the rice pot" was once a true portrayal of the ecological environment here.

One of the precious resources of this wasteland is the land, which is formed over thousands of years with a thick layer of humus, that is, fertile black soil, which contains about 10 times more organic matter than loess, and is the most fertile and suitable land for farming. It is one of the three major black soil regions in the world, accounting for 1 5 of the total area of the world's black soil regions. After the founding of the People's Republic of China, half a century of reclamation has made the Great Northern Wilderness an important national commodity grain base with an annual output of 7 billion kilograms.

Among them, the output of soybeans accounts for 37 of the country's total output, and the output of corn accounts for 53 of the country, which has an irreplaceable position in China, which is also the reason why "Beidahuang" is also known as "Beidacang".

However, now, the embarrassment that "Beidakura" is facing is that there are fewer and fewer black lands that it can be proud of and proud of. According to the data, the content of surface organic matter in the black soil area has dropped to between and more than half compared with the initial stage of reclamation. Due to excessive land reclamation, the original ecology here has been severely damaged.

Nature ruthlessly issued huge "fines" to people for soil erosion, river flooding, wind erosion and desertification, abnormal climate, frequent droughts and floods, and reduced grain production.
