Description

"Ecological Environmental Protection and Resource Development" PPT

Part One: The geographical environment of Qinghai-Tibet

alpine climate

Cold in winter and cool in summer

Strong solar radiation

less precipitation

ecosystem

The Qinghai-Tibet region has a high altitude, cold climate, widespread permafrost, poor soil, and a very fragile ecosystem.

For a long time, due to overgrazing and indiscriminate mining, the pastures in plateau pastoral areas have been seriously degraded, soil erosion has intensified, and ecological and environmental problems have become prominent.

Ecological environment protection and resource development PPT, part 2: nature reserves

1. Why do you think the country established the Sanjiangyuan Nature Reserve? (Three rivers refer to the Yellow River, Yangtze River and Lancang River)

The ecological environment in the Sanjiangyuan region has deteriorated seriously (1) The drought climate has increased, overgrazing, excessive digging of medicinal materials, vegetation destruction, and land desertification have developed violently; (2) Lakes have shrunk, wetlands have degraded, and runoff has decreased; (3) Biodiversity types and The number has dropped sharply; it has seriously affected the sustainable social and economic development of the Sanjiangyuan region and the middle and lower reaches.

2. What is the significance of establishing the Sanjiangyuan Nature Reserve?

It is of great significance to protect lakes and wetlands, virgin forests, alpine shrubs, meadow grasslands, rare animals and plants, and the "third pole of the world" landscape in the Roof of the World region. (Protect biological diversity and various ecosystems) Promote the sustainable social and economic development of the source and middle and lower reaches of the Sanjiang River.

Ecological environment protection and resource development PPT, the third part: rich energy and mineral resources

Solar energy: Lhasa is known as the "Sunlight City" (the reason is that the terrain is high, the thin air weakens solar radiation less, and more solar radiation reaches the ground);

Geothermal energy: mainly distributed in the Yarlung Zangbo River Valley (Yangbajing);

Water energy: mainly distributed in the Brahmaputra River, various rivers in the Hengduan Mountains, and the upper reaches of the Yellow River (Longyang Gorge, Yamdrok Lake);

Coal and oil: coal from Yuka, oil from Lenghu (Qaidam Basin);

Lead-zinc mine, salt (etc.): Qaidam Basin. Qarhan has the largest potash fertilizer plant.

Transportation changes

Highways: Sichuan-Tibet, Yunnan-Tibet, Xinjiang-Tibet, Qinghai-Tibet and other highways.

Aviation: The trial flight to Lhasa was successful in 1956, and there are now regular flights from Lhasa to Beijing, Chengdu, Xi'an and Guangzhou.

Railway: Qinghai-Tibet Railway

1. What resources are available for people to develop and utilize in the Qinghai-Tibet region? Why is the Qinghai-Tibet region very rich in solar energy despite its low temperature? Why is the Qinghai-Tibet region rich in geothermal resources? Why is the Qinghai-Tibet region rich in water?

2. What difficulties will the Qinghai-Tibet Railway encounter during the construction process? What environmental problems may it cause? What is the meaning of construction?
