Part One: Agricultural Planning

Please make reasonable agricultural planning for the four major regions and explain the reasons.

China has solved the problem of feeding its 1.3 billion people, which is a contribution to the world.

At present, my country's output of grain, meat, cotton, peanuts, rapeseed, fruits and other agricultural products ranks first in the world. The per capita possession of cereals is close to the world average, and the per capita possession of cotton exceeds the world average.

In the picture, the terraced fields in the hilly area have been reclaimed to the top of the mountain to develop food production. Do you think this development and utilization is reasonable? Why?

unreasonable

This will lead to increased water and soil erosion, and the soil on the top of the hills will be poorer, which is not conducive to food production.

Natural conditions

Yi Mu Ze Mu

There is less precipitation and lush pasture, which is suitable for the development of animal husbandry.

Food is suitable for food

The terrain is flat, the soil is fertile, and the water source is abundant, which is conducive to farming.

yilinzelin

The terrain is steep and water and soil are easily lost, making it suitable for forestry development.

Fishing when appropriate

The rivers and lakes along the coast are rich in water resources and suitable for the development of fisheries.
