摘　　要：咸潮入侵一直是威胁粤港澳大湾区居民生活生产用水安全、制约其经济发展的重要因素之一。为准确、高效、稳定地监测区域内咸情,咸潮监测技术不断发展,从人工观测发展到定点在线自动监测,再发展到卫星遥感观测。高精度温盐深仪是一种基于高精度、高稳定性模数转换电路的咸潮监测设备,其温度分辨率可达0.0001℃,电导率分辨率可达0.0001 mS/cm,性能较先进,在粤港澳大湾区多处站点的应用结果表明:它能准确、稳定地监测水体含氯度,且体积较小、便于携带,提高了咸潮应急监测工作效率,为粤港澳大湾区抵御咸潮入侵、制定“压咸补淡”措施提供技术支撑,应用前景广泛,后续可以考虑结合卫星遥感观测技术,进一步提高咸潮监测的空间尺度。Salt tide invasion has always been one of the important factors threatening the water safety of the residents in the Guangdong-HongKong-Macao Greater Bay Area(GBA)and restricting its economic development.In order to monitor regional salinity accurately,efficiently and stably,the salt tide monitoring technology has developed from manual observation,fixed-point online automatic monitoring,and then to satellite remote sensing observation.The high-precision Conductivity-Temperature-Depth Monitoring System is a salt tide monitoring equipment based on high-precision and high-stability analog-to-digital conversion circuit.Its temperature resolution can reach 0.0001℃,conductivity resolution can reach 0.0001 mS/cm,and its performance can reach the international advanced level.The application results of several stations in the GBA show that:It can accurately and stably monitor the chlorine content of water bodies,and is small in size and easy to carry,which improves the emergency monitoring efficiency of salty tides,provides technical support for the GBA to resist the invasion of salty tides and formulate measures to suppress salty tides and make up for desalinization,and has broad application prospects.In the future,satellite remote sensing observation technology can be considered to further improve the spatial scale of salty tide monitoring.
