This region is a testament to the ever-changing forces of nature.

Climate Wonders

Alpine Cold and More

The Qinghai-Tibet Plateau experiences a unique alpine climate due to its high terrain. The annual temperature variation is minimal, but daily temperatures exhibit significant fluctuations.

Large Diurnal Changes

The thin atmosphere at high altitudes leads to significant diurnal temperature shifts. Days are characterized by intense solar radiation, causing rapid temperature increases. Conversely, nights cool swiftly as the atmosphere struggles to retain heat, resulting in substantial temperature differences throughout the day.

Small Annual Variations

Despite its high altitude, the Qinghai-Tibet Plateau remains relatively cool during the summer. In contrast, winter benefits from abundant sunlight, as the plateau’s thin atmosphere allows for stronger solar radiation. As a result, this region maintains a milder winter compared to many other areas, including the northeastern part of China.

Abundant Sunshine

The high altitude and thin atmosphere in the Qinghai-Tibet Plateau enable strong solar radiation, providing ample sunshine. This unique combination of geographical features results in an environment that stands apart from any other in the world.

Climate and Precipitation

Unpredictable Precipitation

In this region, precipitation exhibits an uneven distribution throughout the year, characterized by distinct dry and wet seasons. The rainy season occurs from April to September annually, with precipitation gradually diminishing from the southeast to the interior of the northwest plateau. This pattern is influenced by both the southwest monsoon and the region’s topography. Conversely, the dry season spans from October to March of the following year, with precipitation levels dropping significantly, accounting for less than 1% of the annual total.

Rivers: The Lifeblood of Asia

The melted ice and snow in the Qinghai-Tibet Region serve as the source for numerous renowned rivers in Asia. Iconic waterways such as the Yangtze River, Yellow River, Lancang River (Mekong River), Nu River (Salween River), and Brahmaputra River (Brahmaputra River) all originate from this region. These mighty rivers flow through dramatic canyons within the mountainous terrain surrounding the Qinghai-Tibet Plateau. Their swift currents, significant drops, and abundant hydraulic resources play pivotal roles in the ecosystems and livelihoods of millions.

Lakes: Jewels of the Plateau

The Qinghai-Tibet Plateau boasts the highest concentration of lakes in the country, covering over 45% of the total lake area in China. Notable lakes in the region include Qinghai Lake, Namtso, Selin Co, Zhari Nam Co, Dangra Yum Co, Yangtze Lake, Zhuoyongcuo, and more. Most of these lakes sit at altitudes exceeding 4,000 meters, making them the highest lake areas on Earth. While Eling Lake and Zhaling Lake in the eastern region are freshwater outflow lakes, the majority of lakes in the Qiangtang Plateau are inland saltwater lakes and salt lakes.

Inland lakes serve as the initial stage in the formation of saltwater lakes. These lakes, where runoff flows in but doesn’t flow out, accumulate salt over time. The Qinghai-Tibet Plateau’s year-round low temperatures, limited rainfall, intense sunlight, and restricted water circulation accelerate the evolution of these lakes into saltwater bodies. Qinghai Lake, the largest in the country, becomes a temporary habitat for migratory birds during spring and summer, earning its nickname, “Bird Island.” Namtso, the world’s highest-altitude lake, holds sacred significance in Tibetan culture. Both of these lakes, like many in the region, are saltwater lakes.

Diverse Vegetation

The Qinghai-Tibet Region showcases a remarkable diversity of vegetation influenced by both horizontal and vertical differentiation.

The unique alpine environment of the Qinghai-Tibet Plateau is characterized by widespread frozen soil. Predominantly, the soil types in this region include cold desert soil and mountain meadow soil. These soil compositions are a testament to the extreme conditions and challenging terrain that define this remarkable geographic wonder.

In summary, the Qinghai-Tibet Region is a geographical treasure trove that showcases nature’s most extraordinary facets, from dramatic climate patterns to the origin of Asia’s iconic rivers, the splendor of its lakes, the diversity of its vegetation, and the unique soil types that define its alpine environment.

Bountiful Resources

1. Abundant Solar Energy

The Qinghai-Tibet Region enjoys a surplus of solar energy resources, with approximately 1,000 more annual sunshine hours compared to areas at the same latitude in the east. Lhasa, Tibet, particularly stands out as the “Sunlight City” with over 3,000 hours of sunshine annually. This abundance of sunlight is attributed to the region’s low latitude and the high angle of the sun at noon. Additionally, the high altitude, thin atmosphere, and frequent sunny days contribute to a weakened effect on solar radiation.

2. Rich Geothermal Reserves

Situated near the convergence of the Eurasian and Indian Ocean plates, the Qinghai-Tibet Region experiences geological activity that results in numerous hot springs, springs, and boiling springs. This area is endowed with a wealth of geothermal resources. Notably, southern Tibet, within the Brahmaputra Valley, boasts significant geothermal resources and is home to the largest geothermal power station in the country, the Yangpajing geothermal power station.

3. Abundant Wind Energy

The region is characterized by abundant wind energy potential, thanks in part to its high altitude and relatively flat terrain. These conditions create an ideal environment for harnessing wind power, offering vast opportunities for renewable energy generation.

4. Rich Water Energy

Abundant water energy resources are a significant asset of the Qinghai-Tibet Region, primarily concentrated in two key areas. The great bend of the Yarlung Zangbo River in southern Tibet and the upper reaches of the Yellow River in Qinghai are rich in water energy resources. The upper reaches of the Yellow River have undergone extensive development, including the construction of major power stations like Longyang Gorge.

5. Abundant Mineral Resources

The Qaidam Basin in the Qinghai-Tibet Region is renowned as a “treasure basin” due to its rich mineral resources. Here are some of the key mineral resources found in the region:

These abundant resources contribute to the region’s unique economic and ecological significance, making the Qinghai-Tibet Region not only a geographic marvel but also a treasure trove of natural wealth.

Types of Agriculture

Alpine Pastoral Areas

In the alpine pastoral areas, livestock such as yaks, Tibetan goats, and Tibetan sheep thrive despite the high altitudes, cold temperatures, hypoxia, and low atmospheric pressure.

River Valley Agricultural Areas

River valley agriculture is primarily distributed in the Yarlung Zangbo River Valley and Yellow River Valley. These areas offer favourable conditions with low-lying terrain, relatively abundant heat, and significant temperature variations between day and night. These conditions promote the accumulation of organic matter and nutrients in the soil.

Additionally, the low temperatures in these areas result in longer crop growth cycles, fewer pests and diseases, and high-quality produce. The relatively flat terrain along river valleys is also conducive to farming, and the availability of water resources enhances agricultural productivity.

Crops cultivated in these regions include highland barley, wheat, peas, and more, adapted to the specific climatic and geographical conditions.

Industrial Characteristics

Outstanding Features

The industrial foundation in the Qinghai-Tibet Region is relatively weak. However, the region has a notable presence in the livestock product processing industry and mining industry within the country.

Transportation

Transportation Challenges

Transportation in the Qinghai-Tibet Region faces significant challenges due to its lofty terrain. High mountains, deep valleys, frozen soils, and fragile ecosystems create obstacles to transportation infrastructure development.

Main Modes of Transportation

Highways

Highways play a crucial role in the region’s transportation network. Lhasa serves as the central transportation hub, with trunk highways such as Sichuan-Tibet, Yunnan-Tibet, Qinghai-Tibet, Xinjiang-Tibet, and China-Nepal highways connecting various counties and regions. Most counties now have road access, facilitating connectivity.

Railways

Railway networks are particularly vital in Qinghai. Notable railways include the Lanzhou-Qinghai Railway, Qinghai-Tibet Railway, and Lanzhou-Xinjiang High-speed Railway (passing through Xining). However, the challenging terrain has posed significant difficulties for transportation development, hindering local economic growth. Efforts are underway to improve railways in Tibet, including the southern section of the Qinghai-Tibet Railway (Golmud-Lhasa) and the Lhasa-Shigatse Railway, which opened in 2014 and is accessible to trains.

Qinghai-Tibet Transportation: Maintaining Frozen Soil in Roadbeds

The Qinghai-Tibet Railway faces the challenge of preserving permafrost in the “thousand-year-old permafrost” area, especially during the summer when rising temperatures can lead to the melting of frozen soil, causing roadbed instability. To address this issue, three important technical measures have been implemented:

1. “Hot Rod”: Often referred to as a “refrigerator” without electricity, this method involves the installation of a row of thick metal rods, resembling guardrails, on both sides of the roadbed in frozen soil areas. These “hot rods” are positioned 2 meters apart, rising 2 meters above the road surface and penetrating 5 meters below the roadbed. The rods are hollow and closed, filled with liquid ammonia, and equipped with heat sinks on top. Liquid ammonia, with its propensity to transition into a gas, acts as a “freezer,” maintaining the roadbed’s frozen state during the summer.
2. “Riprap Roadbed”: Often described as a natural “air conditioner,” this approach involves the placement of a layer of gravel with a certain thickness in the middle of the upper roadbed in frozen soil areas. The gaps between the gravel are left unfilled, allowing for airflow with the external environment. This structure functions as an “air conditioner,” ensuring that the temperature of the frozen soil layer remains relatively stable, unaffected by external temperature changes, and effectively preserving its stability.
3. “Sunshade Board Roadbed”: Also known as a dry bridge, this method serves as a heat-insulating “coat.” A layer of sun-blocking plates is erected on the slope of the sunshade board roadbed to reduce the impact of solar heat on the roadbed’s temperature.

Residents
