What is the status quo of cultivated land in China?

The current situation of cultivated land in China is that there is more than one and three less, and one more refers to the total amount of cultivated land.

One more refers to: that is, the total amount of cultivated land. The three lessities refer to less cultivated land per capita, less high-quality cultivated land, and less cultivated land reserve resources.

I am aware of the current situation of land resources in the country

1.Farmland resources are relatively scarce, and there is little land for good quality

With the development of the economy, China's per capita land resources are gradually shrinking, and the cultivated land is also decreasing. Meantime. The quality of cultivated land in China is generally low. Among them, the area of superior land is 100 million mu (10,000 hectares), which only accounts for the total area of cultivated land in the country.

2.The degradation of land resources is more serious

The continuous degradation of land resources in China is mainly manifested in the large reduction of the amount of cultivated land, serious desertification, serious soil erosion, and serious barren land basin of agricultural land. For example, real estate occupies a large amount of land resources, agricultural cultivated land resources are occupied, irrational or overutilized, and the greening construction is not perfect, which are the causes of land degradation.

3.The phenomenon of enclosure is frequent

Although many localities have relevant land management systems, there are still some areas that ignore the system and have the phenomenon of using land before approval and exceeding its authority. Similar to the real estate development boom, enterprises develop a large amount of land to develop the real estate industry, resulting in a large amount of land resources being encircled. In some localities, a large amount of land has been enclosed by industrial and commercial capital in rural areas, resulting in non-grain and non-agricultural conversion.

These are all wastes of land resources.

Kiss! Hello, happy to answer your <>

The current situation of cultivated land resources in China, from the perspective of natural factors, is the basic national condition of cultivated land, which can be summarized as "one more and three", that is, the total amount of cultivated land is more, the per capita cultivated land is less, the high-quality cultivated land is less, and the cultivated land reserve resources are less. The per capita arable land is small and unevenly distributed.

China's land area is 9.6 million square kilometers, ranking third in the world, and it can be said that it is a vast territory. However, due to the small amount of available land and the large population, China's land resources are relatively poor, especially the cultivated land that is the basis of agricultural production is even more scarce. According to the data compiled by the national land survey, China's cultivated land area is 100 million mu, and the per capita cultivated land is only one mu, which is less than half of the world average and only 37 percent of the world's per capita cultivated land.

The quality of cultivated land is poor and the degradation is serious. 66% of the country's cultivated land is distributed in mountainous, hilly and plateau areas, and only 34% of cultivated land is distributed in plains and basins. The overall quality of arable land is not high, with a difference of 150,200 kg in grain yield compared to developed countries or developed agricultural countries.

There are still 91 million acres of cultivated land in the country with a slope of more than 25 degrees, and long-term cultivation is not conducive to soil and water conservation, so it is necessary to gradually return farmland. The reserve resources of cultivated land are seriously insufficient, and the utilization rate of cultivated land is low. China has 100 million mu of arable wasteland resources, and according to the reclamation rate of 60%, 100 million mu of cultivated land can be reclaimed.

However, due to the requirements of ecological protection, the development of cultivated land reserve resources is strictly restricted, and the development of reserve resources to supplement cultivated land in the future is very limited. Hope mine can help you <>

Do you have any other questions?

The reality of cultivated land in our country is:

1. The location of cultivated land is fixed. The immobility of cultivated land leads to the limitation and regionality of its location, and also leads to the uneven fertility of cultivated land in different locations.

2. The area of cultivated land is limited. China's 9.6 million square kilometers of land area is fixed, cultivated land is also available, cultivated land is a non-renewable resource, will be reduced, so we must take corresponding measures to supplement cultivated land.

3. Scarcity of supply. The amount of cultivated land is limited, and it is necessary to ensure food security while ensuring development, which leads to the indefinite expansion of cultivated land.

4. It is difficult to change the direction of use. "It is easy to occupy the cultivated land and difficult to recover", the construction of the occupied cultivated land only needs to occupy the land to be used, but the land that has been built and reclaimed as cultivated land is huge, and the cultivated land of the construction reclamation is low, and the topsoil stripping technology of the cultivated area can indeed protect a part of the high-quality cultivated land resources, but the soil fertilization needs to be energetic for a long time.

The basic status quo of agriculture:

The rural labor force is decreasing, the cost is high, the land is wasted, the infrastructure is requisitioned, the cultivated land area is decreasing, the crop output is decreasing, and the relative income of agriculture is declining year after year. China's crop seeds are controlled by foreign capital, and grain is dependent on imports.

Most of the newly reclaimed or reclaimed cultivated land, because of its poor soil fertility and low yield, is still facing the fate of being abandoned, and the endless abandonment is just a waste of reclamation and reclamation costs at that time; The quantity of cultivated land has been preserved, but the quality of cultivated land cannot keep up with it, and the yield continues to decrease, which is also the problem of supplementing cultivated land.

The basic status quo of cultivated land in China is "one more and three less", that is, the total amount is large, the per capita cultivated land is small, the high-quality cultivated land is small, and the reserve resources are small.

1. The per capita cultivated land area is small.

China is rich in land resources, with less per capita occupancy and relatively less cultivated land resources. In recent years, due to the increase of various non-agricultural land, cultivated land resources are becoming less and less, and now China's per capita cultivated land area is only 139 acres.

2. There is little high-quality arable land.

Among China's cultivated land resources, there is little high-quality cultivated land, and the proportion of high-yield fields and medium-low-yield fields is three, and medium-low-yield fields account for seven. In recent years, due to the pollution of industrial wastes, coupled with improper land use and natural reasons, many cultivated lands have been affected by salinization and desertification, and now there are fewer high-quality cultivated land resources in China.

3. Insufficient reserve resources.

Theoretically, China has 200 million mu of cultivated land as a reserve resource, but after combining factors such as water, light, and heat, only 40% of the cultivated land with relatively good conditions is available. Key oak acres.

The national conditions of cultivated land resources in China

China has many people and little land, and arable land resources are scarce. Of the 9.6 million square kilometers of land territory, only about 3 million square kilometers of habitable space is suitable for human survival and development, and only about 1.8 million square kilometers are suitable for large-scale, high-intensity industrialization and urbanization development.

The characteristics of cultivated land resources in China show "three less", namely: less cultivated land per capita, less high-quality cultivated land, and less cultivated land reserve resources. With less than 10% of the world's arable land, China carries 22% of the world's population, and the per capita arable land is only mu, less than 40% of the world average, which is equivalent to 1 16 in Canada, 1 10 in Russia, 1 7 in the United States, and 1 2 in India.

Statistics show that high-quality cultivated land and high-yield cultivated land account for only 30% of the total cultivated land in China. Of the 200 million mu of cultivated land reserve resources, only about 40% are suitable for reclamation. Land development and utilization are facing severe challenges, and achieving sustainable development is also facing huge pressure on land resources.

Analysis of the reasons for the decrease of cultivated land in China year by year! What protections are in place?

Hengmei Boshi.

2019-04-18.

China is a large country with a large population, and in order to meet the problem of feeding the population, the red line of 1.8 billion mu of cultivated land has been delineated, but its area is still decreasing year by year. So, what are the reasons for the annual decrease in China's cultivated land area? What protections are in place?

1. The reasons for the year-on-year decrease in China's cultivated land area.

Cause. 1. The construction of the state occupies cultivated land.

Now it is in the stage of rapid development of the national economy, the country occupies a large amount of cultivated land in order to build roads, cities, industrial and mining, villages, etc., and the high-quality cultivated land next to the suburban villages is reduced a lot, and the industrial land exceeds the reasonable limit, and the scale of industrial land is too large and occupies the best area, not only the land yield rate is low, but also pollutes the urban environment.

Cause. 2. Rural homesteads occupy cultivated land.

China's rural population is large, the residence is scattered, the occupation of cultivated land by homesteads is on the rise year by year, and the rural collective economic organization is not perfect, the property rights relationship is not clear, and the approval of homesteads lacks strict management and supervision.

Cause. 3. The construction of development zones occupies cultivated land.

According to the survey, 43% of the national development zones are idle, the land utilization rate is low, the cultivated land area is decreasing by an alarming margin, and the local construction and development zones occupy a large amount of cultivated land for farmers, and the land requisition money for farmers is only a very low compensation standard, or can not be in place, deducted, misappropriated, intercepted, bringing serious social turmoil.

Cause. Fourth, the reduction of cultivated land due to other reasons.

Due to desertification and soil erosion, the fertility of cultivated land will be reduced or seriously lost every year, resulting in soil failure and the area of arable land will be reduced; In some places, due to drought and lack of water, a large amount of arable land is barren; There is a small amount of wasteland suitable for agriculture in China, and the investment in reclamation is large, the cycle is long, and it is difficult to achieve results in the short term, and the policy of returning farmland to forest and grassland has been launched, resulting in extremely limited reserve cultivated land resources that can be developed and utilized.

2. What measures does China have to protect cultivated land?

The Land Management Law clearly puts forward the goal of cultivated land protection, that is, to achieve a dynamic balance in the total amount of cultivated land. The so-called dynamic balance of the total amount of cultivated land refers to the dynamic balance between the supply and demand of the quantity and quality of cultivated land under the condition that the quantity and quality of cultivated land products are constantly growing for the population and the development of the national economy. To achieve this goal, it is necessary to strengthen the protection of the quantity and quality of cultivated land and pay attention to the improvement of the environmental quality of cultivated land.

1. Quantity protection: The specific measures for the quantity protection of cultivated land include the following aspects: first, strictly control the conversion of cultivated land into non-cultivated land, second, implement the compensation system for occupied cultivated land, third, implement the basic farmland protection system, and fourth, promote land development, reclamation, and consolidation.

2. Quality protection: The quality protection of cultivated land includes the following aspects: first, the state formulates measures for the quality protection of cultivated land, such as: preventing soil erosion, desertification, salinization, barrenness, etc., and second, realizing the environmental protection of cultivated land.
