The Qinghai-Tibet Plateau, dubbed as the Roof of the World, is
facing the threat of deteriorating environment, according to a
latest geological survey.
The China Geological Survey Bureau has recently made public of
its milestone geological survey on the Qinghai-Tibet Plateau,
according to which environment of the plateau is getting worse as a
result of geological movement.
Geologists said drought of lakes, shrinking of glaciers and
decrease of grassland are the major problems threatening the
Government statistics show that the desert area on the
Qinghai-Tibet Plateau has expanded to 0.5 million square kilometers
with more and more lakes dried up, making up about 19.5 percent of
the total area.
In addition, from the 1970s to 2002, the grassland in the area
decreased by 24.3 percent, while the glacier area also shrank
147.36 square kilometers each year, said the geologists.
The Qinghai-Tibet Plateau is the cradle of three main Chinese
