What does Sanjiangyuan Nature Reserve protect? Cultivated land and grassland construction land

Sanjiangyuan Nature Reserve is located in Yushu Tibetan Autonomous Prefecture, Guoluo Tibetan Autonomous Prefecture, Huangnan Tibetan Autonomous Prefecture and Hainan Tibetan Autonomous Prefecture in Qinghai Province. The total area seems to exceed 300,000 square kilometers, including the source of the Yellow River, the Yangtze River and the Lancang River, mountainous areas such as Tanggula Mountain and Bayankala, large-scale grasslands such as Hoh Xil, plateau wetlands and glaciers. The average altitude should be above 3500 meters.

There is little cultivated land in Sanjiangyuan Nature Reserve, only scattered in Huangnan and Yushu, Hainan, which is less than 2,000 mu, so it is not protected cultivated land. In the protected areas, except for towns and herdsmen's settlements, large-scale land development and utilization are not allowed, let alone large-scale mineral resources development and heavy chemical industry development. So it is not to protect the construction land.

Qinghai-Tibet Plateau is the roof of the world, an important ecological barrier and water conservation place for the country. Sanjiangyuan Nature Reserve is located in the hinterland of Qinghai-Tibet Plateau, and the protection focus is on comprehensive ecological environment. The main measures are to implement large-scale ecological migration, and to move out the herdsmen in the core area of the reserve from nomadism to settlement; Reduce the number of livestock in the reserve, so that the grassland can be restored and the vegetation can be restored; Prohibit the development of mineral resources and protect the local ecology; Establish a wildlife protection and research mechanism to maintain the local ecological balance.

I am in Qinghai, and I don't care much about Sanjiangyuan Nature Reserve at ordinary times, and I can't say too much. I didn't check the information, but I only know that the establishment of the reserve has many benefits for the country and the downstream areas, but for people located in the reserve, their life and production have been restricted a lot, and their income sources have also been restricted. The local government wants to get funding from the downstream beneficiary areas, but it seems that those areas are not very active. Alas. . . .
