摘　　要：由于受人类活动、气候变化等因素的叠加影响,河口生态系统面临着日趋严重的干扰并呈现出脆弱性,因此,针对界面相关流域水文参数的高精度、实时监测问题,提出了一种基于声学手段的河口区域温流的监测方法,即高频声层析技术.该技术通过反演流域两侧两个声站互易发射的高频声信号,可以获得该流域高时间精度的流速、温度、水位等水文信息,并进行信息快速集成和发布.初步实验结果表明,该声学技术可以有效地实现对河口流域水文参数的实时动态监测(包括极端天气,如台风等),将有助于加深对海陆交界带水动力过程的了解.The ecosystems in coastal areas are sensitive to human activity and climate change.Real-time observations are essential to understand the effects of climate and human perturbation on the environment and ecosystem function.Based on high frequency acous- tic tomography,this study presents a sound technique to monitor coastal surfaces.Tills technique could obtain information of flow, temperature and water level with high temporal resolution by calculating reciprocal sound transmission time.The preliminary experi- mental results show that this technique could effectively monitor hydrological parameters of coastal ecosystems under extreme weather conditions.This could contribute to a better understanding of hydrodynamic forces.
