Read the material and answer the questions. Material 1: Isothermal distribution map of parts of China and climate data map of a certain place in Hainan Island. Material 2: 20 1 1 year 3

(1) Terrain: Kunming is located in the (Yunnan-Guizhou) Plateau, and Taipei is located in the plain. Different topography leads to different temperatures; Location: Kunming is located inland and Taipei is located along the coast. In winter, there are obvious differences between the two places affected by land and sea. (Or Kunming has a strong continental climate and Taipei has a strong maritime climate) Ocean current: Taipei is affected by the warming of Japanese warm current in winter, and the temperature is higher.

(2) Low latitude, abundant sunshine and abundant precipitation. Hainan Island belongs to tropical monsoon climate, with little precipitation in winter, and drought affects vegetable production. The low temperature brought by strong cold wave weather in winter affects vegetable production.

(3) The decline of the water level in Qinghai Lake is due to the increase of reclamation and irrigation water in the lake area; At the same time, the population is increasing, and the domestic water consumption is also increasing, resulting in a decrease in the number of people and lakes. The reduction of water surface in Dongting Lake is mainly land reclamation, followed by deforestation, soil erosion and upstream siltation.
