摘　　要：本文根据黄河包头段的水文特征和水资源利用途径及方式,建立了黄河包头段主要污染物混合扩散规律的数学模型。应用I131示踪试验方法获得的污染物输入和环境指标响应的时序数据,采用逐步逼进法计算识别了模型参数。经检验和实测验证,模型模拟结果可以准确反映黄河包头段主要污染物混合扩散规律。因此,黄河包头段主要污染物混合扩散模型的建立,为包头水体功能区划、水环境质量评价、水污染物环境容量确定和总量控制、以及水资源合理利用和产业结构调整,提供了定量分析工具。The mingled and spreaded model of main pollutants is established at the part of yellow river in BaoTou city. It based on the approach and method of hydrology characteristic and water resources utilization. Through I131 track experiments the serial data of the pollution input and the responding of environmental refferance are gotten. The data is worked out to identify the model parameters by the stepwise approach method. Thought validating of the test and the metrical dada, the result of model imitation can accurately reflect the disciplinarian of the main pollution at the section of yellow river in BaoTou. So the establishment of the mingled and spreaded model of the main pollution is able to support the quantitative analysis instrument for water function zoning, water environmental quality assessment , the confirm of water pollution environmental capacity and total amount control, even water resources reasonable use and adiusting industry structure at the section of yellow river in BaoTou.
