The cultivated land.
Irrigated land refers to the land with guaranteed water source and irrigation facilities, which can be irrigated normally and grow xeroxing crops in ordinary years. include
Grow vegetables
And other non-factory greenhouses.
Dry land refers to the land without irrigation facilities, mainly relying on natural precipitation to grow xeroxic crops, including no irrigation facilities, only by
Flood diversion and silting irrigation
The cultivated land.
The calculation method of the cultivated land area is: the cultivated land area at the beginning of the year, plus the cultivated land area increased in the current year, minus the cultivated land area decreased in the current year. The area of cultivated land increased in the current year refers to the current year
The internal cause
Newly cleared land (newly reclaimed land with crops already planted in the current year), infrastructure land under cultivation, river silting,
Land leveling
And the increase of cultivated land due to mountain and water control. The arable land area decreased in the current year refers to the land area of national infrastructure construction in the current year (refers to the construction of water conservancy, roads, railways, civil airports, and construction approved by the competent government departments at or above the county level)
