中文摘要： 针对当前我国河流营养物基准极不完善以及流域人类活动影响导致的参照点缺乏的实际问题，采用野外调查、室内分析、3S技术和统计分析等方法与理论，综合运用参照河段法与历史数据法、基于以流域特性为预警因子的回归模型法、营养物与水体物理-化学-生物指标预测关系法，改进以流域特性为预警因子的回归模型，重点解决基于流域特性为预警因子的回归模型方法定量化程度不高、河流营养物与水体物理化学指标预测关系受冻融作用影响下水文格局变化影响强烈的难题，建立科学的基于定量评估流域特性的东北河流氮磷基准制定的方法体系，为我国区域性河流营养物基准制定提供科学依据。

英文摘要： Current nutrient standards for streams and rivers in China are severe imperfect and the reference reaches are lack in regions that are extensively exploited. That is integrated application of reference reaches, historical data, regression models based on watershed characteristics for pre-warning factors and prediction relationship of nutrient and physical-chemical-biological indexes. The regression models based on watershed characteristics for pre-warning factors is also improved. The methods and principles of field investigation, statistical analysis and 3S technology etc. are used to mainly solve the problem that low quantitative level of regression method based on watershed characteristics for pre-warning factors and prediction relationship of nutrient and the physical-chemical-biological indexes of waterbody intensively affected by hydrological pattern under freeze-thaw action. The final aim is to establish a more sound systematic criteria development methods of nitrogen and phosphorus based on quantitative evaluation of watershed characteristics for streams and rivers in the Northeast China, which will provide scientific basis for regional nutrient criteria establishment for streams and rivers.
