Protection and reinforcement of cultural heritage sites in flood-hit provinces in South China will be a focus of restoration work in the next few years, a senior National Cultural Heritage Administration official said on Saturday.

Government budgets for cultural heritage renovation will give priority to sites affected by natural disasters, said Song Xinchao, the administration's deputy director.

A number of Chinese cultural heritage sites have been affected by flooding in the past few weeks, especially those along the Yangtze River. Statistics from the administration showed that by Thursday, more than 500 cultural heritage sites such as monuments, ancient architecture and bridges in 11 provincial-level regions had been destroyed or damaged by floodwater.

Seventy-six of the sites are under national-level protection, and 187 under provincial-level protection. Jiangxi has been the province hit hardest, with 160 heritage sites ruined by deluges, followed by Anhui with 144, Hunan with 62 and Sichuan with 41.

"The national administration has notified local governments to remain on the highest-level alert and keep an eye out for the latest information on flooding," Song said. "They have been urged to preserve the structural components of damaged cultural heritage properly to minimize losses."

The administration has allocated about 3.5 million yuan ($500,000) to a special fund for cultural heritage rescue work in the provinces. Song said more money and technical support will follow after damage evaluation once the floodwaters recede.

He said emergency management efforts by the administration will include the improvement of its rapid response alarm system to better handle natural disasters such as floods.

"Floodwaters have been a major threat to the safety of Chinese cultural heritage throughout history," Song said. "And these old bridges, city walls and houses often have a poor capacity to counter disasters due to the lasting influence of natural erosion and human activities.

"Ancient Chinese architecture is usually made of wood, tiles and bricks. When reservoirs in the upper reaches discharge waters, these heritage sites cannot withstand the impact of torrents."

Ancient bridges have borne the brunt of the recent flooding, with 70 such heritage sites damaged. In Huangshan, Anhui province, a stone-arch bridge first built in 1536 and rebuilt and renovated several times over the centuries collapsed again. In Wuyuan county, Jiangxi province, a covered bridge first built during the Song Dynasty (960-1279) and most recently rebuilt in the 18th century was also left in ruins.

Song said more research was needed on flood-proofing technologies for cultural relics.

"Speaking of ancient architecture, cultural heritage experts and architects have usually focused on studying their layout, historical context and the structure of components," he said. "However, their capacity to withstand natural disasters has often received less attention, and we have thus lacked a comprehensive system to introduce disaster-prevention technology into renovation work and training programs."

He said the administration will coordinate with different government departments to include the safety of heritage sites in the national disaster prevention and mitigation system, with cultural relics to be treated as "key properties", like human life.

"Once disasters come, more efficient campaigns will be launched to rescue the relics," Song said.

He said a range of modern disaster-prevention technologies and methods will be studied for use in various regions.

Song added that ancient wisdom could also make a valuable contribution.

For instance, the Forbidden City in Beijing, China's former imperial palace, has seldom been flooded since its founding 600 years ago due to its superb sewage system. And the sewage system in the historical neighborhood in Ganzhou, Jiangxi, was designed during the Song Dynasty and still functions well today.

"An important task is to conduct in-depth studies of the extraordinary capacities of ancient Chinese cities and take full advantage of those functions today," he said.
