Total area of cultivated land in China in 1960

China's cultivated land area is 1,432,960 square kilometers.

China's arable land area ranks third in the world, second only to the United States and India. However, due to China's large population, the per capita cultivated land area ranked 126th, and the per capita cultivated land in 2017 was only one mu, which was less than half of the world's per capita cultivated land area.

Canada's per capita arable land is 18 times that of China, and India's is twice that of China. There are already 664 cities and counties in China where the per capita cultivated land is below the warning line set by the United Nations. The cultivated land area of the country has dropped to 1.8 billion mu.

Calculation method of cultivated land area:

The cultivated land area is calculated by adding the cultivated land area increased in the current year, and the cultivated land area decreased in the current year by subtracting the cultivated land area reduced in the current year. The area of cultivated land increased in the current year refers to the area of cultivated land increased in the current year due to the newly cultivated land (newly reclaimed wasteland that has been planted with crops in the current year), the land occupied by infrastructure construction for cultivation, the siltation of river water, the leveling of land, and the control of mountains and waters.

The area of cultivated land reduced in the current year refers to the land occupied by the national infrastructure in the current year (refers to the cultivated land actually occupied by the construction of water conservancy, the construction of roads, railways, civil aviation airports, the construction of industrial and mining enterprises, and the construction of schools approved by the competent departments at or above the county level).

The land occupied by rural collective infrastructure (the cultivated land actually occupied by the construction or expansion of rural enterprises, the construction of water conservancy projects, the construction of roads, and the construction of offices and production facilities, such as drying farms, livestock sheds, pigsties, etc.), the land occupied by individual farmers for building houses, the area of returning farmland for afforestation, the area of returning farmland to pasture, and the area of cultivated land that has actually been reduced due to the abandonment of natural disasters.

According to the results of the 2004 national land use change survey recently released by the Ministry of Land and Resources, the per capita cultivated land area of Chinese has decreased from the previous year's mu to mu.

In 2004, 10,000 mu of cultivated land was occupied for construction across the country, 10,000 mu of cultivated land was destroyed by disasters, 10,000 mu of cultivated land was reduced due to the adjustment of agricultural structure, and 10,000 mu of cultivated land was returned to ecological land, and the above four items reduced 10,000 mu of cultivated land. During the same period, land consolidation and reclamation development supplemented 10,000 mu of cultivated land. In 2004, there was a net decrease of 10,000 mu of cultivated land nationwide.

The Ministry of Land and Resources' analysis of land use changes shows that ecological return to farmland is still the main factor in the reduction of cultivated land. According to the field investigation, in 2004, 10,000 acres of farmland were returned to the country, including 10,000 acres of forest, 10,000 acres of grassland, and 10,000 acres of lakes.

Judging from the results of the land change survey in previous years, the area of cultivated land nationwide has decreased from 100 million mu at the end of October 1996 to 100 million mu at the end of October 2004, with a net decrease of 100 million mu of cultivated land and a decrease from 100 mu to mu per capita.

It is worth noting that last year, China's cultivated land was occupied and compensated, and the cultivated land occupied by various construction projects was generally balanced in terms of quantity, but there was the problem of taking advantage of the superior and compensating for the inferior. Comparing the quality of cultivated land occupied by construction and the quality of supplementary cultivated land, in 2004, 72% of the cultivated land occupied by various constructions had irrigation facilities, and 34% of the supplementary cultivated land had irrigation facilities. Most of the cultivated land occupied by construction is high-quality and high-yield fertile land around residential areas, and most of the supplementary cultivated land comes from the development of unused land.

China's cultivated land area is 100 million mu.

According to the "Communiqué on the Main Data of the Third National Land Survey" issued by the Office of the Leading Group for the Third National Land Survey Manuscript Remainder Survey, the Ministry of Natural Resources, and the National Bureau of Statistics on August 26, 2021, showing that China's cultivated land is 100 million mu, of which 100 million mu is paddy field, accounting for; 100 million acres of irrigated land, occupying; 100 million acres of dry land, occupying. 64% of the cultivated land is distributed in the north of the Qinling-Huai River.

Five provinces, including Heilongjiang, Inner Mongolia, Henan, Jilin and Xinjiang, have a large area of cultivated land, accounting for 40% of the country's cultivated land.

100 million mu of cultivated land located in the area of the three-cropping system in one year, accounting for the country's cultivated land; 100 million mu of cultivated land located in the area of the two-cropping system in one year, occupying; It is located in the area of one cropping system a year, and the cultivated land is 100 million mu, occupying.

Other land area in our country:

1. The garden covers an area of 100 million acres. Among them, the orchard is 100 million acres, accounting for; Tea plantations 100 million acres, occupied.

2. 100 million acres of Jingdan grassland. Among them, 100 million acres of natural pasture land, occupying; 100 million acres of artificial pasture land, occupying.

3. 100 million acres of forest land.

4. 100 million acres of wetland.

5. 100 million acres of urban and village and industrial and mining land. Among them, the village land is 100 million mu, occupying. 6. 100 million acres of transportation land. Among them, 100 million acres of rural roads account for.

China's cultivated land area is 100 million mu.

The Third National Land Survey Main Data Bulletin shows that China's cultivated land is 100 million mu, of which paddy fields are 100 million mu, accounting for; 100 million acres of watered land, occupying; 100 million acres of dry land, occupying. 64% of the cultivated land is distributed in the north of the Qinling-Huai River.

Five provinces, including Heilongjiang, Inner Mongolia, Henan Chunqianhui, Jilin and Xinjiang, have relatively large cultivated areas, accounting for 40% of the country's cultivated land.

100 million mu of cultivated land located in the area of the three-cropping system in one year, accounting for the country's cultivated land; 100 million mu of cultivated land located in the area of the two-cropping system in one year, occupying; It is located in the area of one cropping system in one year 100 million acres of cultivated land, occupying.

The area of cultivated land is calculated as:

The area of cultivated land at the beginning of the year, plus the area of cultivated land increased in the current year, minus the area of cultivated land decreased in the current year.

The area of cultivated land increased in the current year refers to the area of cultivated land increased in the current year due to the reasons of famine and new land reclamation (newly cultivated wasteland that has been planted with crops in the current year), land reclamation for infrastructure construction, siltation of river water, land leveling, mountain control, and water control.

The area of cultivated land reduced in the current year refers to the area occupied by national infrastructure, rural collective infrastructure, individual farmers' houses, afforestation, farmland returned to pasture, and the area of cultivated land abandoned due to natural disasters.

In 2021, the average cultivated land area of Chinese was square kilometers.

Although the total area of cultivated land in China is relatively large, the area of cultivated land per capita is relatively small, only 1 4 of the world's per capita cultivated land area. By 1995, the per capita cultivated land area was greater than that of Chipi hectares in some provinces and autonomous regions, mainly concentrated in the northeast and northwest of China, but the hydrothermal conditions in these areas were poor and the level of cultivated land production was low.

Areas with relatively good natural and productive conditions, such as Shangli, Dan, Beijing, Tianjin, Hunan, Zhejiang, Guangdong and Fujian, have less than hectares of cultivated land per capita, and some areas such as Shanghai, Beijing, Dayang, Guangdong and Fujian are even below the minimum per capita hectare proposed by the Food and Agriculture Organization of the United Nations. The organization considers it below this limit. Even with modern technology, it is difficult to ensure food self-sufficiency.

Relevant knowledge

China has about 100 million hectares of forest land, accounting for the world's total forest area, ranking eighth in the world. However, the per capita cultivated land of Chinese is only about 1 3 hectares of the world averageThe forest coverage rate is only 13% (the world average coverage rate is 22%), ranking 121st in the world, and China occupies about 1 hectare of forest land per person, which is only 1 5 of the world average.

There is slightly more natural grassland, and China occupies about 1 hectares per person, which is less than 1 2 of the world average. In the sum of the land used in agriculture, forestry and animal husbandry, China occupies an average of hectares per capita, and the maximum number does not exceed hectares, which is only 1 4 to 1 3 in the world.

As of 2021, China's cultivated land area is 1432960 square kilometers (the data is 2018 statistics). The area of cultivated land in China is mainly distributed in the eastern coastal monsoon area, concentrated in the northeast, north China, the middle and lower reaches of the Yangtze River, the Pearl River Delta and other plains, intermountain basins and hilly areas.

According to the data of the third national land survey, the total area of cultivated land in China is about 100 million mu at the end of 2019.

China conducts a national land survey every 10 years, and compared with the second national land survey of 100 million mu of cultivated land 10 years ago, the "three adjustments" found that the total amount of cultivated land in China has decreased by 100 million mu.

Judging from the transformation of land types in the past 10 years, there are not only the flow of cultivated land to forest land, orchard land and other land types, but also the flow of forest land and orchard land to cultivated land.

Classification of cultivated land

Cultivated land includes ditches, canals, roads and ridges (ridges) with a fixed width of meters in the south and meters in the north; Cultivated land for temporary planting of medicinal herbs, turf, flowers, seedlings, etc., and other cultivated land that has been temporarily repurposed. The cultivated land is divided into three secondary land types: irrigated paddy field, irrigated land, and dry land.

Irrigated paddy fields refer to cultivated land used for planting aquatic crops such as rice and lotus roots. This includes cultivated land where aquatic and xerophytic crops are rotated.

Irrigated land refers to cultivated land that has water source guarantee and irrigation facilities, and can be irrigated normally in normal years to grow xerophytic crops. This includes non-factory greenhouse land for growing vegetables.

Dryland refers to cultivated land without irrigation facilities and mainly relies on natural precipitation to grow xerophytic crops, including cultivated land without irrigation facilities and only relying on flood diversion and siltation.

In 2021, the average cultivated land area of Chinese was square kilometers.

Although the total area of cultivated land in China is relatively large, the area of cultivated land per capita is relatively small, only 1 4 of the world's per capita cultivated land area. By 1995, the per capita cultivated land area was larger than that of the provinces and autonomous regions, mainly concentrated in the northeast and northwest of China, but the hydrothermal conditions in these areas were poor and the level of cultivated land production was low.

Conditions of cultivated land:

1. Watered land refers to the cultivated land that has a certain water source and irrigation facilities in the dry land, and can be irrigated normally in a normal year.

2. Paddy field refers to the cultivated land with ridges (ridges) that can store water and be used to plant aquatic crops such as lotus root, rice, and mat grass. Those who change to dryland crops due to the temporary lack of water storage due to natural drought, or implement rotation of dryland and rice crops (such as rice, rapeseed, wheat, broad beans, etc.), are still counted as paddy fields.

3. Dry land refers to cultivated land other than paddy fields, including irrigated land and dry land without irrigation.

4. Dry land without irrigation conditions refers to dry land without fixed irrigation facilities and water sources, and cannot be irrigated normally.
