The article discusses the progress made in classifying wetlands and their landscapes. Researchers have been focusing on understanding the different types of wetlands and how they are connected within their surroundings. By creating a classification system, they can better analyze the diversity and functions of wetland areas. However, there are still challenges, such as overlooking different scales of classification and simplifying the process based on land use. Future research should pay more attention to urban wetlands and improve the classification system to better study these important ecosystems.
