Evaluation of Xiaoyi River Water Quality in Rural Environmental Monitoring Based on the Comprehensive Water Quality Identification Index Method
Rural ecological environment protection is an indispensable part of achieving rural revitalization,and rural environmental quality monitoring is a prerequisite for evaluating the quality of rural ecological environment.As the most important inflow river in the upstream of Baiyangdian,the water quality of the Xiaoyi River is scien-tifically and reasonably evaluated,which is of great significance for grasping its water quality change patterns.Taking the monitoring of the Xiaoyi River section in rural environmental monitoring in Baoding as an example,6 monitoring sections and 4 main water quality indicators CODCr,NH3-N,TP,and CODMn from the Xiaoyi River section from 2020 to 2023 are selected,and the comprehensive water quality identification index method is used to evaluate the water environment status of this section.The results show that the comprehensive water quality cate-gories of each section of the Xiaoyi River meet or exceed the target requirements of the functional area.However,when evaluating individual pollution indicators,it was found that the main pollution indicator factors in the down-stream Sixiang Bridge section are CODMn and CODCr From the evaluation results,it can be seen that the compre-hensive water quality identification index method can more accurately and intuitively reflect the water quality characteristics and differences in different regions and periods of the Xiaoyi River.The research results can pro-vide theoretical basis for the prevention and control of water pollution in the watershed,and provide data support for the ecological environment protection work in rural areas of Baoding City.
