River and lake health assessment is an important technical means for scientifically analyzing river and lake problems and strengthening the implementation of the river and lake chief system. Under the overall framework of the national river and lake health assessment

this article selects representative indicators and sections to comprehensively evaluate the Qingshui River in Ningxia

a primary tributary of the Yellow River

from five aspects: hydrological integrity

morphological and structural integrity

chemical integrity

biological integrity

and social service function sustainability. The results indicate that the Qingshui River is sub-healthy as a whole

with the vegetation coverage of the riparian zone as the primary influencing factor

followed by the degree of artificial interference and biological factors in the riparian zone. The river's vertical connectivity

the compliance rate of water function zones

and the development and utilization rate of water resources are relatively good. Meanwhile

the Qingshui River has played a relatively good social service function as shown by the flood control and public satisfaction indicators.
