1, the source of high mountains: Tibet is located in the plateau area, with many high-altitude mountains and snow-capped mountains. Glacier meltwater in these mountains and snow-capped mountains is one of the important sources of natural snow-capped mountain water in Tibet. Because the mountainous area is clean, there is no industrial pollution and human activities, the water quality of natural snow-capped mountains is good.
2. Nature reserves: Many natural snow-capped mountains in Tibet have formed nature reserves or national parks. The establishment of these special protected areas means that the ecological environment in these areas has been protected and human activities and pollution sources have been strictly controlled.
