Inland wetlands in China are important for humans but face problems like shrinking size and weakened functions. To understand their health, a study used data to create a system with 15 indicators. They found that in 2018, the area of wetlands increased by 16328 km2 compared to 2010. The average health index in 2018 was 3.45, higher than 3.24 in 2010. Wetlands in better, good, moderate, and poor conditions made up 26.3%, 46.4%, 26.9%, and 0.5% of the total in 2018. This information can help protect wetlands, plan land use, and manage resources effectively.
