摘　　要：为了论证在线光学测试仪器在长江上荆江河段的适用性,进行了TES-91泥沙在线监测系统的比测试验分析。介绍了长江枝城水文站TES-91泥沙在线监测系统的系统组成、工作原理,并对其设备稳定性、仪器示值与实测断面平均含沙量分别进行比测率定试验。结果表明:仪器性能稳定,在线监测泥沙与实测断面平均含沙量具有良好的相关关系。将TES-91测得的含沙量与实测断面平均含沙量建立模型,计算得到的断面含沙量精度较高,适用于枝城水文站泥沙在线监测和报汛。In order to demonstrate the applicability of the on-line sediment measurement instrument in the upper Jingjiang River section,comparative analysis on TES-91 sediment online monitoring technology is carried out.This paper introduces the composition and working principles of the TES-91 sediment on-line monitoring system which has been utilized in Zhicheng Hydrological Station;meanwhile,the stability of the equipment,the indicated value of the instrument and the mean sediment concentration of the measurement cross-section are compared and ana⁃lyzed,respectively.The results show that the instrument performance is stable,and the on-line monitoring of sedi⁃ment has a good correlation with the mean sediment concentration of the measurement cross-section.After establish⁃ing the model of sediment concentration measured by TES-91 sediment on-line monitoring and the mean sediment concentration of the measured cross-section,the calculated mean sediment concentration of the cross-section has a high accuracy,which is suitable for on-line sediment monitoring and flood reporting of Zhicheng Hydrological Sta⁃tion.
