Dongting Lake, a tra-ditional tourist location, is one of the five largest freshwater lakes in China and a Grade 5A National Scenic Region. This study objectively analyzes the scenic resources of South Dongting Lake, and presents a model based on Quantifi- cation Theory I to assess wetland scenic landscapes. Employing a multilinear regression relationship between land-scape factors and their associated scenic value, we built up the Wetland Landscape Quantification Model (WLQM), which was used to classify 221 landscapes into five grades. Finally, some suggestions are proposed regarding quantita-tive assessment and its use for the sustainable development of wetland environments.展开更多
