The study analyzed changes in wetland landscapes in Henan Province from 1980 to 2015. The researchers found that the total wetland area increased by 28%, with constructed wetlands like paddy fields and reservoirs expanding while natural wetlands like marshes and lakes decreased by 74%. Economic factors were linked to changes in wetland types, with socioeconomic development driving these shifts. The proportion of wetland habitat in Henan Province is low compared to the national average, highlighting the need for more focus on restoring natural wetlands in the region.
