With the rapid socio-economic development, a series of functional decline of river system has emerged, such as water pollution, environmental degradation and river shrinkage. The health of ecological river and its comprehensive management has become a hot topic in many countries and regions. Based on the combined influence of various factors, the multiple index system of river health assessment in the upstream of Hun River is established by Driving Forces-Pressure-State-Impact-Responses Model, the evaluation of river health is calculated by the Variable Fuzzy Assessment. The result shows that the river health assessment value is 2.944, which belongs to the weak state of sub health. And given this existence of the research section is located in the upstream of Hun River, carrying a remarkable ecological service potential. Therefore, it is of significant importance to protect, improve and repair the river ecological environment.
