Since 2002, the Wuyuan Bay area in Xiamen — now known as the city's "green lung" — has undergone ecological restoration, systematic management, and integrated development. 

Today, it preserves parts of its original abandoned farmland and marshland while introducing over 400 plant species, including trees, shrubs, and herbs. The area brings together aquatic and wetland plant zones, aquatic plant communities, and reed beds, making it a vital stopover for migratory birds.

Its capacity to provide ecological services has continued to grow, making Wuyuan Bay a rare ecological space that brings together a diverse range of natural assets — including waterfront views, hot springs, lush vegetation, wetlands, and coastal bays.

The ecological restoration of the bay has directly revitalized Xiamen's yacht and sailing industry. Wuyuan Bay alone now offers 351 standard berths, while the city as a whole maintains over 400 vessels and handles more than 1 million passenger trips for recreational sea outings each year. The annual output value of the marine leisure tourism sector and its supporting industries now exceeds 1 billion yuan ($148 million).

Tong'an Bay, Xiamen's largest inland bay, covers a sea area of approximately 101.48 square kilometers with a coastline stretching 74.7 kilometers. Today, the bay presents a vivid picture of harmony between people and the sea — golden sandy beaches, crystal-clear waters, and residents enjoying the scenic waterfront trails. 

As the ecology has improved, so have the surrounding values. Many former fishing villages have undergone remarkable transformations, turning muddy shallows into popular seaside destinations.
