n order to scientifically evaluate the current water resources status of the Pearl River, a three-level evaluation index system of high-quality water resources in the Happy Pearl River is constructed and an evaluation model is established. Each index weight is determined by the coefficient of variation method, and the comprehensive score of high-quality water resources is calculated using the weighted average method, based on which, the grade of the water resources is categorized. Guangdong Province, which is the most representative area in the Pearl River Basin, is taken as an example to verify the application of the proposed high-quality water resources evaluation model. The results show that the current high-quality water resources in Guangdong Province are generally not good, and the water resources problems in different regions varies greatly, which is consistent with the actual local conditions, indicating
that the proposed evaluation model is feasible. The evaluation results and suggestions can provide some reference for the further construction of high-quality water resources in Guangdong Province.
