Ecological risk assessment and difference analysis of pit ponds under different ecological service functions-A case study of Jianghuai ecological Economic Zone

As a critical ecosystem type, wetlands have received extensive attention from scholars worldwide. Previous studies have mostly taken the entire wetland as the research object, and there is a lack of differentiated research on wetland subsystems. Ponds are a vital component of wetland ecosystems, and...
