摘要
以沱江干流上四个重要水质自动监测断面:宏缘、幸福村、脚仙村、大磨子水站为研究对象,采用地表水环境质量标准中的单因子法,评价2017年水质自动监测数据,选取溶解氧、氨氮、高锰酸盐指数和总磷四个指标研究水质时间变化特征,并使用Pearson相关系数法对研究区八个水质监测参数相关性进行分析,认为该研究区水质呈现好转趋势。
In the main stream of Tuo river, four important water station;hong yuan, xing-fu village, jiao-xian village, da mo-zi as the research object, using the single faetor method of the surface water environment quality standard, evaluating the water quality of automatic monitoring data in 2017,studied the time changes of water quality of dissolved oxygen, ammonia nitrogen, potassium permanganate index and total phosphorus, using the Pearson correlation coefficient method to analysis the correlation of the eight monitoring parameter in the studied area. The results showe the water quality in the study area presents positive tendency.
