【摘要】 从三个方面，即泥沙颗粒本身的性质，污染水体中泥沙运动特点如污水氧化塘中的泥沙运动、河口段的泥沙运动，天然水体中污染物如重金属、难降解有机污染物、营养性污染物和油污染物迁移转化、归宿现象，阐述了将环境科学主要是水环境化学、环境地球化学、水化学和水利工程科学主要是水力学、泥沙运动力学结合起来研究水环境问题的重要性和必要性。更多还原

【Abstract】 The problems of three aspects, properties of sediment particles, characteristics of sediment motion in polluted waters, such as, sediment motion in the sewage oxidation pond and in river mouths, and transport transformation of heavy metal pollutants, non degradable organic matters, nutritional sustances and oil pollutant in natural waters, were discussed in this paper. According to these discussion, it is necessary to using environmental sciences, such as, water environment chemistry, environmental geochemistry and hydrochemistry, and hydraulic sciences, for example, hydraulics and mechanics of sediment motion to study the problems in aquatic environment.更多还原
