Ningdong immigrants

(1) is close to the origin of raw materials. Reduce transportation costs and approach the consumer market.

(2)① Overgrazing leads to serious grassland overload; (2) Over-reclamation has caused extensive vegetation destruction.

(3)① Relieve the pressure of tight power supply and energy shortage in our province; ② Relieve the pressure of coal transportation; ? ③ Optimizing the energy structure is beneficial to environmental protection.

(4)① Make the population capacity in the south more reasonable, which will help the remaining population to get rid of poverty and become rich; (2) it is beneficial to restore the natural ecology in the south and reduce soil erosion.

Test analysis: (1) According to the materials, there are more than 0.3 million cows in this area, so the development of dairy production is close to the origin of raw materials. Shanghai is the main consumer market of dairy industry, and long-distance transportation needs convenient transportation conditions. (2) Area C is located in the west of Daxing 'anling, a semi-arid grassland and pastoral area, and the vegetation destruction is mainly due to too many aspects and excessive reclamation. (3) Pay attention to the impact on Shandong Province, that is, the impact on the importing areas. We can learn from the influence of West-to-East gas transmission on the eastern import areas and analyze it from the aspects of energy, economy, transportation and environment. (4) The mode of migration should belong to ecological migration, and we can understand the influence of population migration on the place of emigration from textbooks, mainly from the aspects of ecological environment, alleviating the contradiction between man and land, and economic development.

Comments: This question is generally difficult. Students only need to master the important information of the materials, combine the general situation of regional geographical environment in China, and call the content analysis of the teaching materials on west-to-east gas transmission and population migration. Students should pay attention to "combining material analysis" and pay attention to knowledge transfer and application ability.
