To ensure the health of rivers and achieve sustainable and coordinated development of human society,this study in-troduced the concept of"multifunctional rivers"based on an analysis of various river functions.We constructed a multifunctional river health assessment index system,which encompasses flood control and drainage functions,natural functions,ecological func-tions,environmental functions,resource functions,and cultural functions.Using the Xiaoqing River in Shandong Province as a case study,this research employed the AHP-fuzzy comprehensive evaluation method to conduct a multifunctional assessment of the Xiaoqing River before and after management interventions in 2007 and 2019,respectively.The evaluation results indicated that in 2007,the operational status of various functions of the Xiaoqing River was"inferior,"displaying weak multifunctionality.Specific indicators such as the fish population index,sediment pollution index,water quality,average river slope,and navigational water depth assurance rate were rated as"inferior,"with the primary constraining criteria being environmental and resource functions.In 2019,the operational status of the various functions of the Xiaoqing River was improved to"good",showing a significant en-hancement in multifunctionality.The resource function exhibited the most substantial improvement,transitioning from"inferior"to"excellent",indicating that by carrying through a series of comprehensive management measures,the river's functions gradually recovered.The evaluation results have revealed the developmental status of various functions of the Xiaoqing River after its man-agement,aiming to provide a reference for the future enhancement of the river's functions and its management and development.
