Landscape Aesthetics Quality Estimation Method for Check Dams─Application of the Fuzzy Logic System

The check dam is one of the primary constructions across rivers in watersheds. Its main purpose is to decrease the effects of sediment yield from upper areas to lower areas populated by human beings and buildings. However, the existence of these dams usually runs counter to the natural ecological environment and visual landscape. Based on the three major elements of check dam formation- form, color and texture- which are derived from the expert model- this study aims to de- termine the evaluation criteria and weight for the landscape aesthetics quality of check dams with the Delphi Method, Analytic Hierarchy Process (AHP), and expert questionnaires. It further combines the Fuzzy Logic System to establish the evaluation model. Three cases were used to test our model, and the preliminary results showed it had the advantages of both the expert and psychophysical model. We expect it will provide engineering designers with an integrated model to combine check dam de-
