Is the Yellow River Golden Triangle a futures?

(1) is located in the combination zone of China and the west, with the advantages of connecting the east with the west and shining north and south, and convenient transportation. Rich in energy such as coal and water; There are abundant bauxite, copper and other non-ferrous mineral resources nearby. (4 points)

(2) After the Yellow River rushed out of the mountain pass, the channel widened, the velocity gradually decreased, and the sediment carried by the river formed a river alluvial fan. (3 points)

(3) Soil erosion (1)? Pay attention to the protection of vegetation in the development process; Topsoil should be stored in a planned way, and surface vegetation should be restored in time by mining stones (or reclaimed). (2 points)

Test analysis:

(1) According to the first document, the Yellow River Golden Triangle in Henan, Shanxi and Shaanxi is located in the combination zone of China and the West, which has the advantages of connecting the east with the west and shining north and south. There are railways such as Longhai Line passing by, and the transportation is convenient. The region is rich in energy such as coal and water, which provides sufficient power for nonferrous metal smelting. There are abundant bauxite, copper and other non-ferrous mineral resources nearby, close to the origin of raw materials.

(2) The alluvial fan of the Yellow River is located to the east of Taihang Mountain in North China. After the Yellow River rushed out of the mountain pass, the river channel became wider, the terrain was flat, the velocity of flow gradually decreased, and the sediment carried by the river formed a river alluvial fan.

(3) The area is located in the Loess Plateau, and the most serious ecological environment problem is soil erosion. Loess soil is loose and easy to lose. In the process of development, we should pay attention to protecting vegetation, storing topsoil in a planned way, restoring surface vegetation in time by mining stones, and doing reclamation work in time to reduce soil erosion.
