摘　　要：输入响应模型是定量描述污染源与环境目标关系的有效工具.基于河流监测统计资料和多年水文数据,计算了第二松花江各断面化学需氧量输入单位污染源时对控制断面的影响系数;评价了各污染源对控制断面的贡献率,其中,饮马河输入对第二松花江出口断面的松林断面水质贡献率最大,为24.46%,镇江口、西大嘴子断面紧随其后,贡献率分别为15.29%和14.25%;可以确定河流城市段是水质改善优先控制区域.建立的输入响应模型可靠,可为制定流域水环境管理和污染防治规划提供科学依据.The input response model is an efficient tool for quantifying the relationship between pollution source and environmental tar get. The influence coefficients of control section were calculated when the chemical oxygen demand of each section was input unit pollu tion source in the Second Songhua River on the basic of water quality monitoring and hydrological data. The pollution contributions of different pullution sources to control section were evaluated. The pollution contribution of Yinmahe River to Songlin section of the Sec ond Songhna River was largest, accounting for 24.46% , while Zhenjiangkou and Xidazuizi monitoring sections followed were 15.29% and 14.25% respectively. The city sections of rivers were determined to be the priority control areas when improving water quality. The input response model was so reliable as to provide scientific basis for establishing water environmental management and pollution control plan.
