2011-2022年贾鲁河流域水质时空变化特征
Temporal and Spatial Variation Characteristics of Water Quality in the Jialu River Basin from 2011 to 2022
摘要
Abstract
The pollution load of the Jialu River constitutes approximately one-ninth of the total load in the Huai River Basin.To achieve sus-tainable development in the Jialu River Basin,it is necessary to conduct water quality assessment.This article was based on monthly monito-ring data from 9 monitoring sections in the Jialu River Basin from 2011 to 2022.It combined single factor evaluation method and comprehen-sive pollution index method to evaluate water quality,and used principal component analysis to identify the key indicators influencing water quality in the basin.The results indicated that:Temporally,the pollution level of the basin water body showed an overall decreasing trend.After 2017,the water quality was consistently rated as lightly polluted.Spatially,the pollution severity of river segments decreased in the fol-lowing order:Zhengzhou Segment＞Kaifeng Segment＞Zhoukou Segment.The variation in water quality exhibited distinct spatial characteris-tics.The primary pollution source in the Zhengzhou Segment was industrial wastewater,whereas pollution in the Kaifeng Segment was mainly influenced by the chemical products manufacturing and food processing industries.In the Zhoukou Segment,the pollution originated primarily from urban domestic sewage.关键词
