With the guidance of river health theory,the paper built Dongtiaoxi river basin hydrodynamic model, water quality model and river health evaluation model respectively, and established river health warning coupled model on the basis of above. The quantitative health assessment index of the current status of Dongtiaoxi river calculated by the former model shows that it belongs to the third grade “sub-health”. This paper proposed that the protection and utilization of Dongtiaoxi river should not only limit to the support of engineering measures such as bydrotechnics and so on. In order to make the“sub-health” status of Dongtiaoxi river develop for good direction, it is necessary for us to strengthen the management of sustainable water resources in the future.
