ABSTRACT
As the key source for freshwater resources, urban rivers are essential for human survival and urban
socio-economic development. Recently, the functions of urban rivers have been damaged by increasing
human activities. A better understanding of the health state of urban rivers is the basis of sustainable
urban planning. To this purpose, this research took the Jinshui River as a research area. An indicator
system for urban river health evaluation was first established using the driving force-pressure-stateimpact-
response (DPSIR) framework. The health state of the Jinshui from 2008 to 2017 was then
assessed based on the urban river health index, which was calculated by the improved fuzzy matterelement
extension model. The results show that the overall health status of the Jinshui has improved,
from its unhealthy state in 2008-2016 to a sub-healthy state in 2017. Corresponding response measures
have achieved certain results, which have led to an improvement in the health state of the river. However,
its health still faced many problems, including pressure from a rapid urbanization rate and population
density, a large amount of sewage discharge, and serious water pollution. In general, the health of the
Jinshui was still on the low side. Therefore, to ensure sustainable water environment in the region, it is
necessary to further govern the water environment and improve the health status of urban rivers. This
research can help government easily understand an urban river’s health state and formulate effective
measures in the future.
