The Qingtongxia Reservoir Wetland Nature Reserve stands as a testament to nature's resilience and the power of ecological restoration along the Yellow River. A hydraulic hub transformed by over five decades of sediment accumulation and dedicated conservation, it is now Ningxia's largest wetland sanctuary, spanning over 20,000 hectares. By reclaiming nearly 5,600 hectares of illegally farmed land and restoring vast natural habitats, this area has become a vital "migratory hotel" for 179 bird species, including rare black storks and golden eagles. Today, the sight of thousands of birds thriving in these pristine marshes reflects the successful balance between human engineering and the thriving biodiversity of the Yellow River Basin.
