Analysis on Water Quality Variation Characteristics of Gumagan Canal from 2016 to 2023

摘要:

基于2016—2023年古马干河水质监测数据，采用趋势分析法和季节性Kendall检验法分析了古马干河水质年内和年际变化特征。结果表明:古马干河水质总体良好,且有变好趋势,年内水质汛期优于非汛期,夏秋季节水质优于春冬季节。

Abstract:

Based on the water quality monitoring data of Gumagan Canal from 2016 to 2023, the intra-annual and inter-annual variation characteristics of its water quality were analyzed by trend analysis and seasonal Kendall test. The results show that the overall water quality of Gumagan Canal is sound and presents an improving trend. Within a year, the water quality in flood season is better than that in non-flood season, and the water quality in summer and autumn is superior to that in spring and winter.
