The Yungang Grottoes, one of the three largest major cave
complexes in China, is facing a life or death situation, with
humans as the judges deciding its fate.
The legal information Web site efaw.cn reported that Yungang
Grottoes, located on the southern foot of Wuzhou Hill, 16
kilometers west of Datong in Shanxi province, has been severely
damaged by human activities and natural influences.
"If we do not take action, the grottoes will be gone forever," a
researcher from the Yungang Grottoes Research Institute said.
Dubbed a treasure house of ancient Buddhist art, the grotto
complex is composed of more than 51,000 Buddhist statues, ranging
from 3 centimeters to 17 meters in height. Most of them were
constructed during the Wei Dynasty in the mid-fifth century, when
Chinese Buddhism was at the peak of its popularity.
The statues are among the few remaining historical relics from
the dynasty.
The most significant statues in the complex are those of its
five emperors, Yuan Jinghu, director of the research institute,
said.
The grottoes were included on the United Nations Educational,
Scientific and Cultural Organization World Cultural Heritage List
in 2001.
Hundreds of thousands of visitors come to pay their tributes
every year, but few of them are concerned or have even noticed the
gradually decay of the Buddha images.
Many of the statues' surfaces have flaked off as they have
weathered, and some of their faces have been completely worn away,
Wen Xiaolong, a researcher from the institute, said.
Some of the statues have even collapsed, and other caves and
niches can break down at any time.
"The sandstone has become very crisp, and it will slake off upon
a light touch or stroke," Wen said.
Water penetration is a major natural destroyer of the grottoes,
said Director Yuan Jinghu. With the downpours directly washing
their bodies, and the accumulated water eating out their basements,
the statues suffer the most serious erosion in July, August and
September, when large quantities of rainfall hit the region.
But weather is not the only source of the damage. Datong, the
city where the statues sit, is a longtime industrial city famous
for its coal production.
The floating coal dust, mixed with the sulfur dioxide produced
from coal burning, are two more culprits behind the statues'
decay.
"The combination of the dust and gas brings fatal chemical
reactions to the sandstone statues," Yuan said.
Although the government has allocated over one hundred million
yuan for the construction of a new coal transport route far from
the Yungang Grottoes and a large annual sum to maintain the
grottoes, there is still another threat, in the form of increasing
numbers of tourists.
"Besides the intentional infringements, such as littering and
excessive touching or improper climbing, the carbon dioxide that
humans breathe out is also corrosive to the statues," the director
said.
Yuan is concerned for the future of the statues, and said that
as humans, visitors should understand and respect the statues'
importance.
"The statues have lives like human beings, and if we protect
them, they will live. If not, they will die, and later generations
will never have the chance to encounter such glorious art," Yuan
said.
