The invention relates to the technical field of water environment treatment and biodiversity protection technologies, in particular to a method for determining a water quality improvement target of a water body based on diversity of aquatic animals. Comprising the following steps: step 1, constructing an aquatic animal diversity index system; step 2, matching water quality data and aquatic animal diversity data, wherein the water quality data is an independent variable data set, and the species number, population number and biomass survey data of aquatic animals are dependent variable data sets; step 3, utilizing statistical analysis software to establish a relation curve of each dependent variable and each independent variable, and utilizing an equation to solve water quality data when the variety number, population number and biomass of the fishes, the benthonic animals and the filter-feeding zooplanktons are maximum; and 4, determining a water quality improvement target. According to the method disclosed b
