Section 4: Sustainability Challenges
Key environmental achievements:
✓ Air quality coordination (PM2.5 variance reduced to 10% across region)
✓ Yangtze River ecological restoration (¥320 billion invested)
✓ Coastal protection system (200km of smart seawalls completed)
✓ Circular economy initiatives (88% municipal waste recycling rate)

As the Yangtze Delta generates 28% of China's GDP with just 2.1% of national territory, its development offers crucial lessons in balancing economic growth with environmental protection and cultural preservation.
