Popis: A river is a water container. Moreover, rivers and riverside green spaces are both important ecological gene pools. The functions of water, drainage, and ecological conservation are under serious consideration because of increasing global water issues. However, an assessment method that is integrated with multiple thinking is lacking. An urban river ecosystem quality assessment model cannot be viewed only with a hydraulic engineering perspective because a river ecosystem combines economic, social, and natural aspects. In this study, a literature review is developed and the basic architecture is indexed to increase the objectivity of the index system. The goal of sustainable urban river assessment is to establish an initial questionnaire containing assessment model indexes. A total of 23 indicators are identified by using fuzzy number calculations of expert questionnaires. These are divided into six categories: water quality, biological, sediment, stream conditions, vegetation, and river type.
