摘　　要：本研究旨在全面评估传统光学浊度计(OBS-3A、OBS-3+和RBRsolo)与新型光学浊度计(AQUAlogger310TYPT)在悬沙浓度观测方面的性能,探究进一步提升悬沙浓度观测数据质量的可行性。通过室内实验,分析了量程、高频数据稳定性及粒径敏感性等关键指标,提出了针对不同观测需求的设备选择建议。现场观测实验初步验证了AQUAlogger310TYPT与OBS-3+同步观测在提升近底悬沙浓度观测数据质量方面的有效性。然而,未来研究仍需深入探讨悬沙粒径变化对观测结果的影响,掌握观测水域悬沙粒径变化规律,以便优化修正方法,进一步提高观测数据的准确性和可靠性。This study aims to comprehensively evaluate the performance of traditional optical turbidimeters(OBS-3A,OBS-3+,and RBRsolo)and a new optical turbidimeter(AQUAlogger310TYPT)in observing suspended sediment concentration,and to explore the feasibility of further improving the quality of suspended sediment concentration observation results.Through indoor experiments,key indicators such as measurement range,high-frequency data stability,and particle size sensitivity were analyzed,and equipment selection suggestions for different observation needs were proposed.Field observation experiments have initially verified the effectiveness of synchronous observation of AQUAlogger310TYPT and OBS-3+in improving the quality of near-bottom suspended sediment concentration data.However,in order to optimize the correction methods and further improve the accuracy and reliability of the observation results,future research still needs to explore the impact of changes in suspended sediment particle size on observation results,and grasp the patterns of suspended sediment particle size changes in the observation water area.
