An environmental evaluation report on the Tibetan plateau called for building an ecological civilization model area in Changtang, a habitat for wild animals including Tibetan antelopes and yaks.
The report on environmental change was published Wednesday by the Institute of Tibetan Plateau Research under the Chinese Academy of Sciences.
It said the Changtang area, the nation's highest vulnerable environment, is facing risks including severe thawing of glacier and frozen ground against the backdrop of global warming.
Vegetation degradation and desertification are also at play, with various environmental factors in fragile balance.
According to the report, human activities including increased tourism and overgrazing are also posing threats.
Since the area is important to the environmental change of East Asia and South Asia, the report proposes that a model of green development and enhanced environmental protection should be adopted for the area.
