2.
Aimed at the specific characteristics of agricultural non-point source pollution being difficult to monitor and control in irrigation areas,and based on the viewpoint of unit analysis,a concept of load contribution rate was put forward.
针对灌区农业非点源污染难以监测控制的具体特点,基于单元分析的观点,提出了负荷贡献率的概念,并在此基础上,建立了灌区农业非点源污染负荷估算方法;以青铜峡灌区为例,利用2005—2006年灌溉周期灌排水质监测试验资料对灌区年农业非点源污染矿化度、铵氮、总氮和总磷负荷进行了估算,并与平均浓度法进行比较。
