为提高河流管理质量，在已有河流生态系统健康研究的基础上，提出了基于尺度划分的河流健康评价理论。以滦河为例，建立了其上游、中游和下游的评价指标体系，通过构建改进的模糊物元可拓模型对滦河河流生态健康进行了评价。结果表明：滦河上游、中游、下游均存在一定程度的不健康，滦河全河总体为轻度疾病状态，评价结果与实际相符。因此，本文方法具有合理性和有效性，可用于其他区域的河流生态健康评价。

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.
