Historical Echo: When Urban Parks Became the Lungs of the City

Urban park service preferences in Chinese cities—air purification, recreation, and balanced bundles—track closely with neighborhood income levels and historical patterns of environmental stress, mirroring trends seen in industrial-era European cities. These bundles are not merely aesthetic choices but indicators of how urban populations adapt to externalities that shape livability and, by extension, economic positioning.
It began not with ecology, but with desperation: in 1848, as cholera swept through London’s overcrowded streets, Edwin Chadwick and John Snow linked disease to filth and stagnant air, sparking a movement to embed green lungs within the city. The creation of public parks was never just about beauty—it was a survival strategy. Over a century later, in 2026, Chinese citizens overwhelmingly prioritize air purification in urban parks, unknowingly echoing the same cry for breathable life. The demand bundles identified by Wu et al. are not mere preferences but fossil records of urban trauma—each bundle a fingerprint of how people experience the suffocation of modernity. Just as Victorian elites sought moral uplift in manicured lawns while the working class fought for spaces to gather and breathe, today’s balanced, recreation-dominated, and purification-focused groups reflect parallel divides in environmental agency and vulnerability. The irony is stark: we keep rediscovering the same solutions, yet fail to see that the pattern itself—the cycle of degradation, demand, and partial remedy—has become the problem. —Catherine Ng Wei-Lin
