Read the materials and maps and answer this question. Material: Natural rubber is a tropical cash crop and also a raw material for manufacturing tires. Natural rubber likes high temperature and humidity. Looking at the map, we can see that the number ① in (1) represents the largest Three Gorges water conservancy project in China and ② the Hong Kong Special Administrative Region. (2) The distribution characteristics of natural rubber in China are: mainly distributed in the south of the Tropic of Cancer (Yunnan, Guangxi, southern Guangdong and Hainan Island), because natural rubber is a tropical cash crop, and the south of the Tropic of Cancer is tropical, with high temperature and rainy weather, which is suitable for the growth demand of natural rubber. Some automobile manufacturers in China have moved their tire factories to Southeast Asia because they are close to the origin of raw materials. (4) There are few central cities in Taiwan Province Province, because the central part is mountainous. (5) The poet Yang Sheng 'an praised Kunming for "the weather is often like February and March, and flowers are always in spring". The natural reason for Kunming's "Four Seasons in bloom" is that Kunming is located at a low latitude with mild winters. Kunming is located in Yunnan-Guizhou Plateau, with high altitude and cool summer. (6) The favorable natural conditions for agricultural development in H area are: warm and humid climate, rain and heat; Flat terrain and fertile soil; Rivers and lakes are densely covered with abundant water.

So the answer is: (1) Three Gorges; Hong kong; (2) Mainly distributed in the south of the Tropic of Cancer (Yunnan, Guangxi, southern Guangdong and Hainan Island). Natural rubber is a tropical cash crop, and the area south of the Tropic of Cancer is tropical with high temperature and rainy, which is suitable for the growth demand of natural rubber. (3) Close to the origin of raw materials; (4) The middle part is mountainous; (5) Kunming is located at a low latitude with mild winters; Kunming is located in Yunnan-Guizhou Plateau, with high altitude and cool summer. (6) The climate is warm and humid, with simultaneous rain and heat; Flat terrain and fertile soil; Rivers and lakes are densely covered with abundant water.
