Abstract
By constructing a health evaluation index system for the Shiku river,a total of 16 indicators were evaluated at four criteria levels,namely,basin,water,biology,and social service functions,to obtain the health status of the Shiku river in Meizhou city.The results showed that the Shiku river is a Class Ⅱ river and is in a healthy state.Conservation measures were proposed for health problems such as poor longitudinal connectivity of the Shiku river and low retention index of large benthic invertebrates and fish,so as to better play the ecological environment and social service functions of the Shiku river.
