② The plains of the middle and lower reaches of the Yangtze River and the Pearl River Delta have low terrain, fertile soil, and crisscross river branches, which are convenient for irrigation and conducive to the development of freshwater aquaculture; the Sichuan Basin has fertile purple soil; the Hengduan Mountains are rich in forest resources, with many tree species and little human impact, which is conducive to development. forestry production.

③The Yangtze River Basin has a long history of agricultural production and high production levels.

Unfavorable conditions for agricultural production

① During the drought period in the Jianghuai region, temperatures are high, precipitation is low, and evaporation is strong, which easily affects rice production. Typhoons in the southern coastal areas in summer and autumn have a great impact.

② The area south of the Yangtze River is a red soil distribution area. The soil is highly acidic and is not conducive to the development of planting industry.
