| 摘 要： | 采用污染分担率法确定评价因子,应用综合污染指数法对2001至2007年六安市地表水进行全面评价并分析其变化趋势。结果表明:1)在2003到2007年度,七大河渠除淠河总干渠和史河水质状况良好外,其余河流水质较差,尤其是淠东干渠和东淝河水质污染更为严重;史河、淠东干渠和东淝河水质呈现好转趋势,东淝河水质改善较为明显,而淠河总干渠、淠河、沣河和杭埠河水质呈恶化趋势,杭埠河水质恶化尤为显著;TN、TP、NH3-N、CODMn、COD为主要超标因子,TN为首要污染因子,水质主要受氮磷营养元素和有机污染。2)在2001-2007年期间,磨子潭和佛子岭水库水质尚清洁,但梅山、响洪店、龙河口水库受到轻污染;除梅山水库外水质均呈恶化趋势,而磨子潭水库水质恶化趋势显著;TN是主要超标因子,水质主要受生活污水和农业面源中氮磷营养元素的影响。

| Abstract: | The paper uses the pollution sharing rate to determine the evaluation factors and applies the integrated pollution index to give the comprehensive evaluation of the surface water in Lu'an city and the analysis of the changing trend from 2001 to 2007.Here does the study show:1) during the period between 2003 and 2007 among the seven canals,the quality of the water in the Main Channel of Pi River and Shi River was good,the rest was rather bad,and especially Pidong Channel and Dongfei River were worse;the qual... |
