Analysis of Water Quality Characteristics in Guilin Section of Xiangjiang River by an Improved Comprehensive Pollution Index Method Based on Entropy Weight Method
摘要
Abstract
Seven water quality indicators of the Guilin Section of the Xiangjiang River from 2019 to 2023 were selected for research.The significance of spatio-temporal difference of water quality indicators was analyzed by one-way ANOVA.The improved comprehensive pollution index method based on entropy weight method was used to assess the water quality characteristics of the basin in the past five years.Pearson correlation analysis was performed to identify the dominant factors influencing water quality.The results show that the water quality in the Guilin section has consistently improved over the past five years,with all samples classified as Class I.Water quality during the non-flood season was superior to that during the flood season.Spatially,the upper reach exhibited the best water quality,followed by the lower reach,while the middle reach showed relatively poorer conditions.The primary pollution sources were identified as domestic sewage and agricultural runoff.关键词
