摘要
利用渭河系列水质监测资料,采用频率曲线适线法来确定统计参数,并对渭河1990～2000年污染强度的污染历时及变化趋势进行评价,最后分析了渭河陕西段水质动态变化规律,为合理的治理渭河的污染提供科学的依据。
Duration of pollution is a dynamic research for water quality in different time. This paper based on the series data of water quality in Weihe river and used the method of frequency curve to evaluate the duration of pollution of water quality in 1990～2000, and analyze the change of water quality in order to provide the scientific bases for the treatment of Weihe river.
