Grottoes sand erosion efforts bear fruit
Print Edition
THE renowned Mogao Grottoes, a UNESCO World Heritage Site in northwest China’s Gansu Province, have been protected from sand erosion and encroaching desert following 70 years of continuous effort, the site’s administration said yesterday.
Wang Wanfu, deputy chief of the Relics Preservation Research Institute under the Dunhuang Academy, said a combined system consisting of barriers, sand and plant belts, patches of grass and gravel have been installed to ward off erosion.
The accumulated sand in the grottoes today has been reduced by more than 85 percent from the amount reported in the 1980s. Damage to murals and colored sculptures in the grottoes has been minimized and the environment around has been improved due to sand control projects, Wang said.
