Fully understanding regional geographical characteristics, developing regional superior resources according to local conditions, developing economy and protecting ecology are conducive to promoting regional sustainable development. Left picture (1) In winter, northerly winds prevail, and cold air masses get some water vapor when passing through Bohai Sea and Yellow Sea. A is located on the windward slope of low hills, and there is more snowfall due to terrain uplift. (Just draw the direction of airflow movement in the valley and one side of the slope of the valley. ) In winter and spring, affected by the mountain wind at night, cold air sinks along the hillside, the cold air gathering temperature at the bottom of the valley is low, and the temperature on the hillside is slightly higher, so the fruit trees are not easy to freeze and bloom early.

(2) A is located in the coastal hills and B is located in the inland plateau; In summer, the precipitation in A is more than that in B, the illumination is weaker than that in B, and the temperature difference between day and night is smaller than that in B; Soil layer a is thinner than soil layer B.

(3) The ecological environment is fragile and the soil erosion is serious; Lack of water; Insufficient transport capacity; Single production structure; Environmental pollution is serious.

(4) Fish scale pit can intercept slope runoff, which can improve the survival rate of tree planting and increase vegetation; Reduce soil erosion, maintain soil and water, and conserve water.

(5) Example 1: According to aeolian theory, loess particles become thinner from northwest to southeast; The loess soil layer in mountainous area is thin or missing. Example 2: stagnant water theory, loess particles from northwest to southeast from coarse to fine. Ex. 3: Weathered residues: After long-term weathering, rocks are constantly broken, forming sand and loess materials.
