摘要：
Based on the comprehensive pollution index method, combined with single factor pollution index method, cumulative anomaly method and other statistical analysis methods, the temporal and spatial variation characteristics of water quality of 7 sections in Lanzhou and Baiyin section of the Yellow River mainstream were quantitatively analyzed. The results show that the comprehensive water quality of Lanzhou and Baiyin sections was good from 2010 to 2019, and the comprehensive pollution indexes of each section were all below 0. 25. The water quality of each section had significant spatial difference(P © 2021, Editorial Board of Water Resources Protection. All rights reserved.
