Self-driving tour of the Sichuan-Tibet small ring line (three or four) Sanjiangyuan 4

The Zaling Lake and Eling Lake at the source of the Yellow River are full of water and grass, and the smoke is vast. Here, you can see the unique wild plants of the plateau everywhere. Among them, the blue-purple flowers are the representatives of the Sanjiangyuan plants. The blue color is not only beautiful, but the more important role is that it can effectively resist the invasion of ultraviolet rays. The ecological environment in the reserve is very fragile. It is recommended not to litter at will, not to destroy the local ecological environment, and not to trample on the plants on the wetland at will when walking by the lake.
