琼江支流蟠龙河水质状况及高时间分辨率下典型月份水质趋势分析OACSTPCD
Water Quality of Panlong River,Tributary of Qiongjiang River,and Analysis on Water Quality Trend in Typical Months Under High Time Resolution
水环境问题关乎人类和生态安全,近年来部分河流富营养化水华现象引发关注.选取四川琼江支流蟠龙河为研究区域,采用单因子评价法、改进的内梅罗污染指数法和主成分分析法分析"十四五"以来蟠龙河水质状况,并利用藻类数据与水质同步监测数据,在高时间分辨率下分析典型月份水质趋势.结果表明:蟠龙河2021年、2022年整体水质较好,氮磷对水质影响最大,2022年4月出现蓝藻水华,上游段元坝子水质受影响较重,Ad、chla、CODCr和TP呈极强的正相关性.同年12…查看全部>>
The issue of water environment is related to human and ecological security.In recent years,the phenomenon of eutrophication and water bloom in some rivers have caused concerns.In this paper,the Panlong River,a tributary of the Qiongjiang River in Sichuan,was taken as a research area;the single factor evaluation method,improved Nemerow pollution index method,and principal component analysis method were used to analyze the water quality of the Panlong River si…查看全部>>
