悬浮体系指悬浮在水中,经过过滤能停留在滤膜或滤纸上的一切物质质点,其中包括泥沙颗粒、浮游生物及各种胶体物质等。悬浮体浓度分布是自然环境条件的综合反映,与物质来源,海洋环流、潮流、波浪等动力要素密切相关。因此,悬浮体浓度及运移途径是测试环境条件的重要参数,对其进行研究将对开发港口、合理利用土地资源、保护生态环境具有重要的实际意义,对于探讨现代沉积过程则具有理论意义。 Suspension means suspended in the water, filtered to stay in the filter or filter on all the material points, including sediment particles, plankton and a variety of colloidal substances. Concentration distribution of suspended solids is a comprehensive reflection of natural environmental conditions, and material sources, ocean circulation, power flow, waves and other dynamic factors are closely related. Therefore, the concentration of suspended matter and its migration path are important parameters for testing the environmental conditions. Studying on it will have important practical significance for the development of ports, the rational utilization of land resources and the protection of ecological environment, which is of theoretical significance for exploring the modern depositional process.
