| Abstract: |
| This paper presents a method to assesse the physical, ecological environment and aquatic habitat of river using high-resolution remote sensing. The indicators used in the model for assessment include ratio of vegetation covering, river sinuosity, natural shoreline of river and its exploration, which can be derived either directly or indirectly from remote sensing images. Therelative significance of these indicators were determined using the Analytic Hierarchy Process (AHP). The model for assessing the physio-ecological environment and aquatic habitat of the river was developed using the fuzzy system. We applied the model to Liao River. The results showed that the quality of the physical and ecological environment in Liao River is in middle-high level, reaching health standard. |
