Read the material and answer the questions. Material 1: Isotherm distribution map in some areas of my country and climate data map of a certain place in Hainan Island. Material 2: 2011 3

(1) Terrain: Kunming is located on the (Yunnan-Guizhou) Plateau, and Taipei is located on the plains. The difference in terrain height leads to temperature differences; Location: Kunming is located inland, and Taipei is located on the coast. In winter, the two places are affected by sea and land differences. obvious. (Or Kunming’s climate is more continental, and Taipei’s climate is more oceanic.) Ocean currents: Taipei is affected by the warming of the Japanese thermal current in winter, and the temperature is relatively high.

(2) Low latitude, sufficient sunlight and abundant precipitation. Hainan Island has a tropical monsoon climate. There is little precipitation in winter, and drought affects vegetable production. The low temperature caused by strong cold wave weather in winter affects vegetable production.

(3) The decrease in the water level of Qinghai Lake is due to land reclamation around the lake area and an increase in irrigation water. At the same time, as the population increases, domestic water use also increases, resulting in a decrease in the amount of water in the lake.

The decrease in the water level of Dongting Lake is mainly due to the reclamation of the lake for farmland, followed by deforestation and land reclamation in the upper reaches, water and soil erosion, and sedimentation.
