Abstract

This study applied emergy ecological footprints (EEF) to investigate a national coastal wetland in Taiwan–Gaomei Wetlands. A wetland ecosystem evaluation model was used to quantify the EEFs and emergy ecological carrying capacity (EECC) of Gaomei Wetlands between 2007 and 2013 to examine the current environmental situation of the area. In addition, we employed the grey model to predict the EEF, EECC, and ecological safety of Gaomei Wetlands. Based on the research results, we provided a reference for environmental policy execution and planning, as well as strategies and suggestions for the sustainable development of Gaomei Wetlands. The results indicated the following: The prediction results of the grey model showed that the 2014–2023 ecological carrying capacities of Gaomei Wetlands decreased and the per capita EFs increased extensively, which enlarged the ecological deficit and elevated the EFI. In addition, the level of 2014–2023 ecological security is higher than that of 7 years ago and is expected to reach the Grade 2 intermediate level in 2021, indicating that Gaomei Wetlands is gradually becoming ecologically unsustainable.
