Abstract:
In order to improve the quality of river management, the river health assessment theory based on the existing study about river ecosystem health and scale division was put forward. Luan River was selected as the research area. Index system was established for its upstream, midstream and downstream, and the improved fuzzy matter-element model was adapted in the assessment of Luan River. The result showed that the upstream, midstream and downstream were all unhealthy to some extent, and Luan River, on the whole, belonged to the mild disease level, which wass consistent with the actual situation. Therefore, this method is reasonable and effective and can be applied in river health assessment in other areas.
