| 摘 要： | 本文用示踪物质模拟污染物在水体中的扩散特性，拍摄得到典型排放方式下浓度场的图象，进而利用数字图象处理技术处理得到浓度场的等浓度线图，直观地表示出示踪物质的浓度分布状态，可为污染物扩散规律研究及水环境质量评价提供必要的依据。同时,本文的实验也表明利用数字图象处理技术进行水体污染物浓度场测量的可行性，具有广阔的发展前景。

| Abstract: | In this paper, a tracer is used to simulate the characteristics of pollutant diffusion in water. Based on the images of typical discharge styles that are recorded on the spot, the application of digital image processing technique is carried out. So we can get the isoconcentration graphs, which show the concentration distribution of tracer directly. According to the graphs, we can carry out the search of the law of diffusion of pollutants and the evaluation of water environmental quality. At the same time, the experiment in this paper also shows the feasibility of pollutant concentration measurement in water body by digital image processing technique. |
