摘　　要：采用水功能过渡区的新理念,根据一维水流的污染物对流扩散方程,提出河流水功能过渡区长度的计算方法,并分析了水功能过渡区长度受水动力条件、污染物特性、底泥释放污染物等影响因素的变化规律,为分析论证水功能区的合理性、可行性以及优化调整过渡区提供了关键技术支撑和科学依据。According to the new concept of water functional transition zone and the one-dimensional convection-diffusion equation, a method for calculating the length of water functional transition zone of rivers was proposed. The variation laws of the influences factors of hydraulic conditions, contaminant characteristics and contaminants released from sediment on the length were studied. This method providesa technical support and scientific basis for demonstration of the rationality and feasibility and optimization of water functional transition zone,
