Scarred Jiuzhai Valley recovers slowly after quake

Over the past year, Ren Guiyuan has spent at least four hours every day surveying Jiuzhaigou National Park in the mountains of Southwest China’s Sichuan Province.

His job is to look for any potential geohazards within the park — a UNESCO World Heritage Site that was rocked by a 7.0-magnitude quake a year ago.

“It may take longer when it rains as I need to go through every corner,” said Ren, who has been working at the park for two decades.

The national park, also known as the Jiuzhai Valley, contains around 20 tourist sites and is known for its spectacular waterfalls, lush forests, serene plateau lakes, and karst rock formations.

Located in the mountains on the eastern edge of the Qinghai-Tibet Plateau, it is one of the most acclaimed tourist destinations in China, but the pristine scenery was left scarred by landslides and falling rocks triggered by the powerful earthquake last August.

Restored beauty

The glassy waters of Wuhua Lake, or the Five-Flower lake, one of the most beautiful lakes in the valley, turned brown after the quake, and a total of 89 spots in the park were left at risk of geological hazards. Many people feared that the region’s breathtaking scenery would be destroyed forever.

However, a year later, the lake has magically regained its original beauty and shines like a sapphire embedded among the valleys.

“The waters in Jiuzhai Valley come from underground rivers, and it purifies itself since 85.5 percent of the park is covered with forests,” said Du Jie with the park’s management bureau.

However, restoring the entire part still takes time and can be a very dangerous process due to its unique karst landforms.

Over the past two months, Jiuzhai County was hit by continual torrential rains, which again triggered mudslides in the park. “The mud and rocks flew from ravines down to the roads under construction, we almost failed to escape,” recalled Xiong Bo, a worker on the site. The second day, seven workers quit.

“One of my other jobs is to inform the workers of possible dangers in time,” said Ren.

Now over a third of the 89 spots have been restored, but the remaining parts are more challenging to fix, as there is no precedent of how to restore a UNESCO World Heritage Site which was severely damaged by a natural disaster.

Scars and difficulties

The famous crystal blue water from Sparkling Lake was almost drained after the earthquake, and its carbonate rocks, formed thousands of years ago at the bottom of the lake, are now exposed to the air.

“The carbonate rocks can quickly become loose and eroded without water. We are closely monitoring the rocks to make sure they won’t pose a threat to the safety of the whole region,” said Zhu Zhongfu, senior engineer at the park’s management bureau.

Another major site, the Nuorilang Waterfall, formed a crack down its middle and stopped flowing after the earthquake. After evaluation, experts used crushed carbonate rocks to repair the fissure and now the falls are back.

“If we hadn’t repaired it, it might have threatened the safety of 19 upstream lakes,” said Du. “Now that the water has resumed its flow, new layers of carbonate rocks will gradually form. We will continue monitoring its recovery status.”

Hope ahead

The powerful earthquake was a blow to the local tourism industry, the region’s primary industry. In 2016, Jiuzhai Valley received 7.2 million tourists, including 180,000 foreigners, with the total tourism revenue hitting 9 billion yuan (US$1.35 billion). Last year, the number of tourists dropped sharply to 2.5 million, with ticket revenue more than halved.

Though part of the park reopened in March this year, it set strict limits on the number of daily tourists. As a result, most hotels have decided to take this opportunity to upgrade facilities.

In Yatun Village, a new road is being planned and a row of Tibetan style log cabins are being built. “We hope the new houses will bring in more tourists and create more jobs in the future,” said Sha Song, a local official.

Many others have joined the post-quake reconstruction, such as Xu Tingfeng, a former chef at a local hotel who is now learning to paint the walls at a construction site. Local authorities said that more than 6,500 local residents in Jiuzhai County have joined the reconstruction work so far.

“I love the lakes and mountains here. So we must take good care of them and pass them on generation by generation,” said Ren.
