Jiuzhaigou, known as a world-class ecotourism destination, was designated a UNESCO Biosphere Reserve in 1997.

Located in Sichuan Province, it lies in the transition zone between the Qinghai-Xizang Plateau and the Sichuan Basin, covering an area roughly three-fifths the size of Hong Kong. Millions of years of geological shifts and glaciation, combined with mountain uplift and water erosion, shaped Jiuzhaigou's deep valleys and terraces, creating its rich natural wonders.

With alpine karst lakes and waterfalls at its core, Jiuzhaigou blends lakes, cascades, snow-capped peaks, and forests into a Y-shaped valley, ranging from 1,996 to 4,764 meters in elevation, dotted with over a hundred lakes and waterfalls.

Nestled in the Minshan Mountains, Jiuzhaigou serves as a climate buffer and sanctuary for rare species such as giant pandas, golden snub-nosed monkeys, and Chinese yews, showcasing the ecosystem's resilience.

In recent years, Jiuzhaigou has partnered with UNESCO's International Centre on Space Technologies for Natural and Cultural Heritage (HIST) to pioneer integrated "space–sky–ground" ecological monitoring, combining satellites, drones, and ground observations to support the protection of natural heritage and biodiversity.
