滩涂为生物多样性和海洋经济奠定了基础。象山湾是一个半封闭的海湾，有大面积的滩涂，以水产养殖闻名。本研究于深秋进行了实地考察，测量了台风“玲玲”期间海湾内滩涂的水位、海流、水温、滩涂温度和浊度数据。现场数据经过良好校准，用于研究滩涂的水动力、温度和浊度。结果表明，两个站都很好地捕捉到了海平面的春季-小潮潮汐周期。春潮和小潮期间最大潮差分别为5.5 m和1.5 m。滩涂偶尔暴露在空气中（30分钟）。海流速度（0.5 Hz）对于水和滩涂温度很重要，特别是在台风期间。这些发现为未来滩涂生态水文学和海岸工程研究提供了实地数据。
Tidal flats provide a foundation for biological diversity and marine economy. Xiangshan Bay is a semi-enclosed bay that shelters large areas of tidal flats, and is known for its aquaculture. In this study, field trips were conducted in late autumn to measure the water level, current, water temperature, tidal flat temperature, and turbidity data of the tidal flat in the bay during Typhoon Lingling. The field data were well calibrated and used to investigate the hydrodynamics, temperature, and turbidity of the tidal flat. The results showed that the spring-neap tidal cycles at the sea surface level were well captured at both stations. The maximum tidal range was 5.5 m and 1.5 m during spring and neap tides, respectively. The tidal flat was occasionally exposed to air occasionally (30 min). The current velocity (0.5 Hz) were important for water and tidal flat temperatures, particularly during typhoons. These findings provide field data for future studies on eco-hydrology and coastal engineering in tidal flats.
