Analysis of Spatiotemporal Characteristics and Causes of Water Quality in Longxi River Based on Online Monitoring
This paper analyzes the spatiotemporal changes in the water quality of the Longxi River based on the automatic monitoring data from 2019 to 2023.The results indicate that the incoming water quality of the Longxi River has a significant impact on the water quality of the Luzhou section;Combining Spearman rank correlation coefficient analysis,it was found that the total phosphorus and permanganate index of the Longxi River inlet sec-tion showed an overall upward trend,while there were varying degrees of improvement in the Luzhou section.There are many agricultural and domestic sources along the Longxi River,coupled with low flow and slow flow during the dry season,which leads to eutrophication in the Longxi River during the dry season,resulting in the accumulation of pollutants and deterioration of water quality.It is recommended to comprehensively improve the water quality of the Longxi River from three aspects:strengthening regional joint prevention and control,manag-ing and protecting water bodies and shorelines,and implementing pollution prevention and control measures.
