The article evaluates the fragility of wetlands in Hangzhou Bay by using satellite imagery and geographic information systems. The researchers found that the wetlands can be divided into three categories based on their fragility levels. Coastal and estuary wetlands are less fragile, while areas near the city are highly fragile due to factors like construction and pollution. Hangzhou city has better wetland protection compared to Ningbo city, which needs more monitoring and protection measures. It is important to protect plants, animals, and habitats in fragile wetland areas to maintain their ecosystem functions.
