The picture on the left is a map of a certain region in my country, and the picture on the right is a schematic diagram of the non-ferrous metal "corridor" in the upper reaches of the Yellow River. Read the picture and answer the following questions. (1) West of Helan Mountain

(1) The lake area is located in an arid and semi-arid area (or a temperate continental climate zone) in the interior of the continent, with low annual precipitation; it is located in an inner flow area, with small river runoff and little water entering the lake. ; Solar radiation is strong (strong light and long sunshine hours), so evaporation is large; windy weather aggravates the evaporation of fresh water.

(2) Distribution: Along the foothills of the Qilian Mountains (or the Hexi Corridor), they are concentrated in the oases in front of the mountains of the Hexi Corridor; Reasons: The foothills area has low altitude and flat terrain; there are many oases in the foothills area and water sources Good condition.

(3) It is rich in non-ferrous metal mineral resources (or rich in mineral resources), convenient railway transportation (no points will be given only for convenient transportation), and rich water energy resources.

(4) Develop domestic and foreign markets; improve transportation conditions; improve scientific and technological levels; and increase policy support. Improvements in refrigeration and preservation technology.

(5) Close some wells: reduce over-exploitation of groundwater and avoid the decline of groundwater levels; compress farmland area: reduce agricultural water consumption and return farmland to forests and grasslands; promote drip irrigation technology: reduce the cost of agricultural production reduce the consumption (or waste) of water resources and improve the utilization rate of water resources (or reduce the waste of water resources); carry out ecological migration: reduce the pressure of population on the ecological environment.
