(2)④

(3) Cold Qinghai-Tibet

(4) Soil erosion of the second loess layer

(5) Qinling? Eight hundred

(6) Tibet

Test analysis:

(1) East China has a monsoon climate. According to the advance and retreat law of summer monsoon, the farther south, the earlier the rainy season comes and the later it ends. In the north, there is little precipitation in spring, strong evaporation and large water consumption for industry and agriculture, which is prone to drought.

(2) ④ is located at the junction of stairs, with large drop, abundant water and hydropower resources.

(3)a is the Qinghai-Tibet region with high altitude, and the most prominent natural environment feature is cold; The Qinghai-Tibet Railway, known as Tianlu, is located in this area.

(4) The area shown in the figure is located on the second step of Chinese terrain. M is the Qinling Mountains in China, and to its north is the Loess Plateau in China. Because of low vegetation coverage, loose soil and heavy rainfall, this area is one of the most serious areas of soil erosion in the world.

(5)M is the Qinling Mountains, and the Qinling Huaihe River Line is the geographical dividing line between the north and the south of China. It is the 800MM annual precipitation line in China, the distribution boundary between paddy field and dry land, the 0℃ isotherm of 1 month, the planting boundary between rice and wheat, the boundary between subtropical and warm temperate zones, the boundary between humid and semi-humid zones, the boundary between subtropical monsoon climate and temperate monsoon climate, and the boundary between animal husbandry and planting. And the dividing line between frozen and unfrozen rivers.

(6) The Tibetan robe on the right is a traditional costume of Tibetans, who mainly live in the Qinghai-Tibet Plateau and belong to the Qinghai-Tibet region among the four geographical regions.

(7) According to the picture, it can be judged that A is the grassland landscape in Inner Mongolia, B is the water landscape in the south of the Yangtze River, C is the landscape in the northwest, and D is the cave landscape in the loess plateau of China, so this topic chooses B.
