What are the location factors of three-dimensional agriculture in South China?

Soil: The proportion of hills and mountains is large and the vertical differentiation is obvious, but the soil has low organic matter, high acidity and heavy soil quality. Three-dimensional agriculture can play the potential of land resources in low mountains and hills.

Relationship between man and land: high population density, less arable land per capita and insufficient reserve resources of arable land. Three-dimensional agriculture can reduce the pressure on cultivated land.

Ecology: The ecological environment in hilly areas is fragile. Three-dimensional agriculture can lay out agriculture, forestry and animal husbandry industries at multiple levels, change the single grain structure and change the ecological environment.
