(18 points) Read the graphic materials and answer the following questions. Lanzhou is located in the upper reaches of the Yellow River and the second largest city in the northwest of China. There are 156 kinds of mineral deposits in Lanzhou.

(1) Clean energy: hydropower, solar energy and wind energy. (Just answer two of them, 2 points)

Water energy: located at the junction of the first and second steps of China's terrain, with a large gap; The river flow is large.

or solar energy: the climate is dry, with more sunny days and less clouds; The terrain is high and the air is thin.

or wind energy: close to the wind source in winter; Located in Hexi Corridor, it has narrow tube effect and strong wind force.

(2) rich in mineral resources and energy; Land resources are abundant and cheap; The labor cost is low. (6 points)

(3) It plays a leading role in regional economic development; Conducive to undertake industrial transfer in the eastern and central regions; Promote the upgrading of regional industries (promote the transformation and upgrading of traditional industries). (6 points)

Analysis of test questions: This question is not difficult. The key to solving the problem is that students can find useful information from the materials in combination with the questions, and also need to refer to the knowledge of regional economic development learned in the textbooks.

(1) The illustrated area is located in the inland area of northwest China, and the clean energy suitable for development includes hydropower, solar energy and wind energy. It is located at the junction of the first and second steps of China's topography, with large drop, large river flow and abundant hydropower resources; The climate is dry, with many sunny days, less clouds, higher terrain, thin air and abundant solar energy resources; Close to the winter wind source, it is located in Hexi Corridor, with narrow tube effect, strong wind power and abundant wind energy resources.

(2) According to the information in the materials, the legend shows that this area has mineral resources and hydropower resources. The new area is located in the north of the original Lanzhou urban area, with concentrated contiguous land and open terrain. Therefore, compared with the first four national new areas, Lanzhou New Area has the advantages of rich mineral resources and energy, rich and cheap land resources and low labor cost.

(3) Lanzhou New District is the first national-level new district in the northwest of China, which plays a leading role in the economic development of the northwest. Conducive to undertake industrial transfer in the eastern and central regions; Promote regional industrial upgrading and promote regional economic development.
