The water environmental condition of the Beiyunhe River, a typical urbanized and semi urbanized river in northern China, is under multiple threats. In this research, through site investigation and sampling, the water quality and habitat quality was evaluated by adopting the comprehensive pollution index method and the expert scoring method. The research analysis shows that: the water quality of the upstream of the main stream was better than that of the downstream, the water quality spatial characteristics were that the water quality of the upstream was relatively good, the midstream took the second place and the downstream was the worst; the water quality heterogeneity characteristics of the river was relevant to the characteristics of different rivers upstream and downstream; the result of the general evaluation of the quality of the aquatic habitats was fair, the evaluation scores of all the monitoring points were higher than 80, the comprehensive index of the habitat quality of the main stream was higher than that of each tributary, so the habitat quality of the main stream was relatively good, and there was little difference in the habitat quality of all tributaries; the main factor that affecting the quality of the river aquatic habitats in the Beiyunhe River was that the artificial disturbance of an urbanized and semi urbanized river is strong, causing relatively single river habitat, which is difficult to form complex and diverse habitats. This research can be provided as a basis for river water environment scientific management of the Beiyunhe River.
