Often overlooked, Marine mudflats stand as Earth's natural sewage treatment plants, orchestrating seawater purification through the harmonious interplay of sediment, microorganisms, and indigenous plant and animal systems.

Recognized as valuable resources, mudflats extend their influence beyond mere functionality, serving as biodiversity havens, wintering habitats, and natural breeding grounds for rare bird species.

According to the International Convention on Wetlands, mudflats reaching depths of up to 6 meters at low tide are considered national territory, with the territorial sea extending only 12 nautical miles beyond that.

These expansive marine mudflat wetlands emerge as treasures, offering not only ecological benefits but also contributing significantly to the conservation of biodiversity.

Nurturing an array of unique ecosystems, marine mudflat wetlands support coral reefs, mangrove forests, and rare species thriving at the interface of fresh and saltwater. These ecosystems possess high ecological value, sustaining the delicate balance of nature and providing a home for diverse flora and fauna.

Therefore, the conservation of mudflats is crucial for maintaining the rich tapestry of life in these critical marine habitats.

By actively participating in restoring these essential ecosystems, China contributes to the global environmental cause and enhances its influence within the international "community of human destiny."

The 21st century is unanimously recognized as the century of oceans, with the global ocean covering 71% of the Earth's surface. However, despite this vast expanse, much remains unknown, particularly in the deep sea and the often-overlooked mudflat wetlands.

Often referred to as the kidneys of the ocean, mudflats play a crucial role in maintaining marine health and balance.

These coastal ecosystems serve as a vital link in the intricate web of life, fostering biodiversity, supporting migratory bird species, and contributing to the overall health of the oceans.

Exploring the mudflats is akin to a treasure hunt, where the explorer patiently scrutinizes the soil, turns over reefs, and carefully searches for organic matter from surface runoff and ocean currents.

This meticulous attention reveals the convergence and deposition of ocean nutrients on the mudflats, creating a dynamic ecosystem that attracts many species, including birds, fish, shellfish, arthropods, and mollusks.

At the foundation of this vibrant ecosystem lies minerals and organic matter washed ashore by waves. These deposits, filtered and consumed by benthic animals like crabs, shrimps, and mud clams, form the cornerstone of a thriving food chain.

This intricate web of life extends to birds, fish, and various organisms that flock to the mudflats, making them one of the most vibrant ecosystems on Earth.

Historically, humanity harnessed mudflats, with ancient records indicating the cultivation of mudflat aquaculture in places like Hainan. Aquaculture practices, including farming seafood such as grouper, spot prawns, oysters, mud clams, paste crabs, and anthropomorphic rockweed, have long been integral to coastal communities.

However, human activities, including land reclamation and environmental pollution, have threatened the delicate balance of coastal mudflat ecosystems. These acts have reduced biodiversity, caused a loss of ecological functions, and caused the gradual endangerment of bird and mangrove species, heightening the risk of extinction.

Recognizing the significance of marine mudflats is paramount in the global conservation effort. Their role as ecological powerhouses, sewage purifiers, and vital components of the oceanic landscape underscores the need for concerted efforts in their protection and restoration.

As we navigate the century of oceans, preserving these hidden treasures ensures a sustainable future for marine ecosystems and humanity.
