Are the climate zones that the Yangtze River, Yellow River, and Lancang River pass through together have alpine climates?

The area where the Yangtze River, Yellow River, and Lancang River flow together is the birthplace of the three rivers, also known as the source of the three rivers. The source area of ??the three rivers is located in the west of my country, with an average altitude of 3,500--4,800 meters. It is the roof of the world. --The hinterland of the Qinghai-Tibet Plateau, southern Qinghai Province, Tanggula Mountains; a plateau and alpine climate.

The Sanjiangyuan is the source catchment area of ??the Yangtze River, Yellow River and Lancang River, the world-famous rivers that gave birth to the Chinese nation and the long history of civilization in Indochina. Known as the "Chinese Water Tower".

Hope this helps
