Which Sanjiang is the source of the Three Rivers?

The "Three Rivers Source" refers to the birthplace of the Yangtze River, the Yellow River and the Lancang River, and is known as the "China Water Tower", which occupies an important position in the ecological situation and national economic development of China and bears an important responsibility in the management and protection of the ecological environment in the western development.

Sanjiang Plain and Sanjiangyuan are two places that farmers are familiar with, so which three rivers do you mean here? Let's talk about it together

Located in the south of Qinghai Province with an average elevation of 3,500-4,800 meters, Sanjiangyuan is the hinterland of the Qinghai-Tibet Plateau, the roof of the world, and the source catchment area of world-famous rivers: the Yangtze River, the Yellow River and the Lancang River (called Mekong River in foreign countries), which has given birth to the long civilization history of the Chinese nation and Indo-China Peninsula. This area is one of the areas with the highest concentration of biodiversity at high altitude in the world.

Rivers, lakes and swamps are densely covered in the source area of the Three Rivers, and snow-capped mountains and glaciers are widely distributed. It is the region with the highest altitude, the largest area and the most concentrated distribution in the world, with a total wetland area of 73,300 square kilometers, accounting for 24% of the total protected area, and is known as the "China Water Tower".

The source of the Three Rivers plays an important role in the ecological situation and national economic development in China, and bears an important responsibility in the ecological environment management and protection of the western development. The establishment of Sanjiangyuan Nature Reserve is of great significance to protect the ecosystem, biological species and genetic diversity in Sanjiangyuan area.

At the beginning of 20 14, the second phase of the ecological protection and construction of the Three Rivers was started, and it became a top priority to explore how to be more harmonious between man and nature. In 2005, the State Council approved the implementation of the master plan for ecological protection and construction of the Sanjiangyuan Nature Reserve in Qinghai, marking the official start of the first phase of the Sanjiangyuan ecological protection and construction project, with a planned area of 6,543,800+0,523,000 square kilometers. More than 20 measures, such as returning grazing to grassland, ecological migration and artificial precipitation enhancement, have been taken to comprehensively restore the ecological environment in the source area of the Three Rivers. Since 2006, the Qinghai Provincial People's Government has cancelled the assessment of the GDP of the Three Rivers Source Region and included ecological protection and construction in the assessment. According to the monitoring, the ecological protection and construction project of the Three Rivers Source has been implemented for nearly 10 years, and the surface water in this area has increased by at least 8.49 billion cubic meters, the area of major lakes has increased by at least 760 square kilometers, and the annual runoff and multi-year average runoff of the Yangtze River have increased by 3.99 billion cubic meters and 750 million cubic meters respectively. The water quality of the main stream has reached or exceeded the second-class standard of the national surface water environmental quality standard for 9 consecutive years. In 20 13 years, the precipitation in the source area of the Three Rivers increased by 429 1000 billion cubic meters, equivalent to the water capacity of 300 West Lakes. "I think the biggest effect since the implementation of ecological protection in Sanjiangyuan is artificial precipitation enhancement. The Sanjiangyuan is deep inland, the climate is dry, and the increase in rainfall has a significant effect on alleviating desertification. " Cai Rengongbao, deputy governor of Yushu Tibetan Autonomous Prefecture, said that the improvement of ecology has restored the wildlife population in the Three Rivers source area. From June 2065438 to June 2009, the government of Yushu Tibetan Autonomous Prefecture in Qinghai Province in the Sanjiangyuan region issued a notice, explicitly prohibiting the release of alien fish species in the Sanjiangyuan waters permanently. If serious consequences are caused, it will be handed over to judicial organs for criminal responsibility according to law.
