摘　　要：简要地阐述了泥沙含量与流量动态测量系统的基本测量原理及其基本组成,包括了4个子系统:自动采样系统,自动测量系统,数据分析、输出及查询系统和操作控制系统。通过大量试验测试,结果表明该测量系统不仅能够达到一定的测量精度,而且还能够实时、在线、动态地测量室内或野外径流泥沙含量与流量,并实现数据便捷地传输、存取等功能。The measurement principle and the mainly components of a dynamic measuring system for sediment concentration and flow rate determination are simply described, including four subsystems such as: the automated sampling subsystem, automated measuring and acquisition subsystem, data analysis/output/retrieve subsystem and operation/control subsystem. Laboratory application experiments and tests of the integrated system indicate that the system has such unique capabilities as short time for high precision measurements, and fast transmission of logged data. The system is so designed that it can be used not only for measuring sediment concentration and flow rate in the laboratory experiments of soil erosion study, but also for field research and for on-site long-term monitoring of soil and water loss from runoff plots.
