| 摘要: |
| 在现有河流水生生境评价方法基础上，充分发挥高分辨率卫星遥感影像在高精度、快速进行河流水生生境信息提取方面的优势，选取植被覆盖度、河岸开发强度、河流蜿蜒度及河流自然岸线保有率等可以直接或间接通过遥感影像提取的指标建立河流水生物理生境遥感快速评价指标体系。采用层次分析法对所选定的评价指标进行权重确定，进而采用模糊评价法建立河流水生物理生境遥感评价模型，以期快速、准确地反映大区域范围内河流生境状况。最后将该模型应用于辽河干流水生物理生境评估。结果表明，辽河干流水生物理生境质量处于中上等，达到了健康的水准，评价结果比较符合辽河干流水生生境健康现状。 |

| 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. |
