【摘要】 本文采用灰色关联法对太子河流域鞍山段水质进行分析评价,选取千山、太平沟、红土岭、五道河源头4个断面,选定总磷、总氮、氨氮、挥发酚、溶解氧5个评价因子,以各断面各季度水质实测数据为参考数列,以地表水环境标准为比较数列,计算关联度,确定水质级别。研究总体表明:鞍山境内的水质较差,受季节因素影响较小。更多还原

【Abstract】 In this paper, the grey correlation method is used to analyze and evaluate the water quality of Anshan Taizi River basin. Four source sections of Qianshan Mountain, Taipinggou, Hongtu Ridge and the headwaters of the Wudao River are selected, and five evaluation factors of total phosphorus, total nitrogen, ammonia nitrogen, volatile phenol and dissolved oxygen are selected. The measured data of water quality in each quarter of each section are taken as the reference sequence, and the surface water environment standard is taken as the comparison sequence to calculate the correlation degree and determine the water quality grade. The overall research shows that the water quality in Anshan is poor and is less affected by seasonal factors.更多还原
