An
Unpolluted and Beautiful City
The ancient city of Lhasa features blue
skies, crystal clear river water, refreshing air, and a beautiful
environment. It is the least polluted and most beautiful city.
The Central Government invested 3.9 million
yuan to build a natural environment monitoring station in
August 1990. This was followed by the construction of three
sample air gathering stations, five environmental noise monitoring
stations, 27 traffic noise monitoring stations, six sample
drinking water gathering stations, and three water quality
monitoring stations. The time when the Tibetan environment
was not monitored is over.
Monitoring results show that the Lhasa
area is basically free from pollution, with the carbon dioxide
density in air being less than 0.1 mg, much lower than the
national standard. In the downtown area, which is densely
populated, the air contains slightly more soot than the other
areas, a result of Buddha worshipping activities. However,
the soot content of the downtown air nevertheless stays below
0.4 mg per cubic meter. The Lhasa River is free from lead,
zinc, copper, and other metallic trace elements, and towns
and villages on both banks of the river cause no pollution
to the river.
The
Tibet Autonomous Regional government and the Lhasan government
have been planting trees in Lhasa for decades. Statistics
gathered in 1991 show that the green area in the city covers
669.7 hectares, including 50.2 hectares of parks, 336 hectares
of lingka woods, 233.3 hectares of lawns and flower beds,
13 hectares of seedlings, and 37.2 hectares of trees and lawns
flanking roads. The greenery averages 12 square meters, ranking
among the first in all of China. The three-river project,
the system for the development of the valleys in the middle
reaches of the Yarlung Zangbo, Lhasa, and Nyang Qu rivers,
brings benefit to the whole area of Lhasa. Several 100-hectare
forests or tree belts have been built in the Nyemo mountain
gully and Painbo river valley, as well as along the Lhasa
river banks.
