基于多元统计分析方法的湟水质量变化及调控对策
|
摘要
为了研究湟水水资源质量的变化,以控制水体污染和保护水环境,根据湟水干流多个断面的2000—2016年水质实测资料,总结整理主要污染因子,运用系统聚类分析方法和季节性Kendall检验分析对湟水流域进行了水质空间、时间上的演变特征分析及水质变化趋势分析,并提出了对策及建议。分析结果表明,湟水水质污染依然严重,污染防治任务重。
In order to study the changes of water resources quality in Huangshui River and to control water pollution and protect water environment,the measured data of water quality from 2000 to 2016 in several sections of the main stream of Huangshui River were summarized and the main pollution factors were sorted out. The spatial and temporal evolution characteristics of water quality and the trend of water quality change were analyzed by means of systematic cluster analysis and seasonal Kendall test analysis. The countermeasures and suggestions were put forward. The analysis results showed that the water quality of Huangshui was still seriously polluted and the task of pollution prevention and control was heavy.
