The main water supply source in Badain Jaran Desert

(1) It can be seen from the latitude and longitude and the outline of land and sea on the map that the Badain Jaran Desert is deep inland, far away from the sea, and the terrain is blocked, so the water vapor is difficult to reach, so there is little precipitation.

(2) The "no ice in winter" in the material indicates that the water temperature is high (possibly from groundwater); The Badain Jaran Desert goes deep inland, with less precipitation and underdeveloped rivers (less atmospheric precipitation and less surface water supply).

(3) As can be seen from the figure, the Badain Jaran Desert is deep inland, with less precipitation and abundant sand sources; It is windy in winter and spring, carrying a lot of dust to accumulate here.

(4) Do you agree or disagree? Just explain the reason. Mainly from the economic and ecological aspects to analyze the reasons.

So the answer is: (1) living inland, far from the sea; The terrain is blocked and water vapor is difficult to reach.

(2) The fault zone passes through this area, and groundwater is exposed at the fault; The land is located in the northwest inland, and the lake does not freeze in winter, indicating that the water temperature is high (probably from groundwater); The climate is dry, evaporation is much greater than precipitation, and rivers are underdeveloped (atmospheric precipitation and surface water supply are less).

(3) The land is located in the northwest inland, with abundant sand sources nearby, windy weather in winter and spring, and a lot of dust has accumulated here; There is high humidity in the sand mountain, and there are many plants near the top, forming a fixed sand dune. With the continuous accumulation of dust, a tall sand mountain has been formed.

(4) agree. Abundant groundwater resources and stable recharge; High quality mineral water with good water quality; Providing production and domestic water (alleviating water shortage) to promote social and economic development;

Disagree. Over-exploitation of groundwater leads to the decline of groundwater level, the drying of sand dunes (vegetation death), the activation of sand dunes and the increase of dusty weather; The groundwater recharge speed is slow, which can not meet the needs of large-scale mining; Lakes are shrinking and biodiversity is decreasing.
