Ecological migration planning of Jinsha River

(1) is mainly located in the monsoon region, with large precipitation and runoff; China is located at the junction of the first and second steps, with a large gap (and concentrated gap) and rich hydropower resources; Multi-canyon terrain, easy to build dams; The local population is sparse and the workload of resettlement is small; Strong policy support.

(2) The climate in mountainous areas is warm and cool, with sufficient precipitation and high humidity in rainy season; High altitude, high atmospheric transparency, sufficient illumination and large temperature difference between day and night; Dense vegetation, many pine trees and oak trees, can provide nutritional support; There are few pests in mountainous areas; Good ecological environment and less pollution.

(3) The price of Tricholoma matsutake is high, the international market demand is large, and the economic value is high. With the increase of local residents' income, picking, processing, transportation and other industries will rise, driving the development of related industries.

Test and analysis: (1) The favorable conditions for the development of hydropower resources mainly include natural conditions and socio-economic conditions. The lower reaches of Jinsha River are quite different, located at the junction of the first and second steps in China, with a large drop; It is also located in the monsoon region, with large precipitation, large runoff, abundant water and abundant hydropower resources. In addition, many canyons are conducive to dam construction. This place is located in the southwest of China, with low population density and the support of national policies, which is suitable for the cascade development of water.

(2) This topic can be analyzed with reference to the natural location factors of agricultural production. The mountainous terrain and cool climate provide water resources for the growth of Tricholoma matsutake. The altitude is high and the air is thin, so the atmospheric transparency is high and the temperature difference between day and night is large. There are many pine trees and oak trees in this area, which can provide nutritional support. In addition, the higher the terrain, the lower the temperature, and fewer pests and diseases, which are beneficial to the growth of Tricholoma matsutake.

(3) Tricholoma matsutake is a rare natural medicinal fungus in the world and an endemic species in Asia. Therefore, the price of Tricholoma matsutake is high, the international market demand is large, and the economic value is high. In the process of "picking, processing and transportation", the income of local residents will be increased and the development of other industries will be promoted.
