摘　　要：根据大宁河唐家湾段的水质应急监测结果,分析了大宁河唐家湾段的物化指标特征、营养状态因子特征、Chla与各指标间的关系等,并对大宁河唐家湾段水体进行了富营养化状态评价。结果表明:唐家湾段面受有机污染严重,并且N/P比例已经适合藻类生长;Chla与CODMn、TP、TN呈显著正相关,与SD、pH呈负相关;对于已发生富营养化的水体,政府立即采取措施对藻类进行控制是十分必要的。According to the result from emergency monitor of quality in Tang-Jiawan stream segment in Da-ning river,the feature of materialized index,nutrition factor with condition and the relation between Chla and other kinds of indexes,etc.are analyzed and its eutrophication status of water is evaluated.The results show that the section of Tang-Jiawan was polluted organically and severely,and proportion of N/P has already provide the situation for seaweed to grow;Chla is positively correlated with CODMn,TP and TN while negatively correlated with SD and pH.It is very necessary for government to adopt a measure immediately to control the seaweed in the water where the eutrophication has already taken place in the water.
