【摘要】 以汾河太原城区南段的实测水质资料为基础,运用单一污染指数法、综合污染指数法给予研究河段的水质评价;应用污染负荷比的方法,分析了河流的主要污染因子,各支流对污染的贡献率。在水质评价分析基础上,建立了多元线性回归河流黑臭指数模型;应用matlab程序化技术进行多元线性回归,确定黑臭指数模型参数;根据黑臭度的定量的分级,用实测数据进行了模型的验证,确立了适合太原城区南段的黑臭指数模型。依据黑臭模型对汾河太原城区南段黑臭的时间与空间分布作定量的研究,为汾河太原城区南段黑臭成因分析提供了一定的依据。更多还原

【Abstract】 This paper takes the Fenhe River’s south segment in Taiyuan City as the object of research.It is based on materials of actual water quality,applies single pollution index,comprehensive pollution index to give the studied river a water quality evaluation.By applying the rate of pollution loads,it analyzes the main factors causing the river to be black and stink and contribute rate of various branches to pollution.Based on the monitoring results and an analysis of pollution factors,the multiple linear regressions index model of rivers’ black and stink is established.Using the technology of Matlab programme for multiple linear regressions,it determines the parameters of the rivers’ black and stink index model.According to the ration graduation of blackness and stinkness,it uses measured data to confirm the model and establishes a suitable black and stink index model of the Fenhe River’s south segment in Taiyuan City.Based on the black-odor model of the Fenhe River’s south segment in Taiyuan City,it does quantitative research on the time and spatial distribution of blackness and stinkness,providing a basis for analyzing the causes of black-odor.更多还原
