Please talk about the difference between the north and south distribution of land resources and water resources in China, and then evaluate the influence of regional matching of water and soil resources on agricultural production. The water resources in China are more in the south and less in the north, which is quite different, while the land resources are more in the north and less in the south. Poor coordination between soil and water, more land and less water in the north, aggravated the degree of water shortage in the north, which is very unfavorable to agricultural production in China. Transfer water through the South-to-North Water Transfer Project; Popularize water-saving irrigation technology in the north; Cultivate new varieties of dry farming.

This topic mainly examines the relevant knowledge of water and soil resources in China. There are many water resources in the south of China, but few land resources in the north. Poor coordination between soil and water, more land and less water in the north, aggravated the degree of water shortage in the north, which is very unfavorable to agricultural production in China. Transfer water through the South-to-North Water Transfer Project; Popularize water-saving irrigation technology in the north; Cultivate new varieties of dry farming.
