摘要
Wetlands are widely recognized as among Earth’s most vital ecosystems.They occupy a mere 5%−8%of our global landmass,but provide unparalleled ecosystem services per unit area compared to any other habitats.Wetlands provide not only sustenance and shelter for livelihoods but also essential ecosystem functions,including biodiversity preservation,climate regulation,hydrological flow regulation,and water purification.For example,wetlands serve as biogeochemical hotspots,actively participating in greenhouse gas exchanges between the Earth’s surface and the atmosphere[1],and peatlands-peataccumulating wetlands-contain the highest soil carbon density and the largest biosphere carbon pool among all ecosystems[2].Often referred to as the“kidney of the world”,wetlands excel at removing pollutants and purifying water。
