Water Flow in Seagrass Ecosystems - Seagrass Density Effects on Water Flow

Field and laboratory experiments were conducted to study the effects of water velocity on bending of shoots and canopy compression at different densities of Amphibolis antarctica and Posidonia sinuosa. A hydrodynamic study associated with the project investigated the differences in water flow caused by manipulating the density of an Amphibolis griffithii meadow.

The laboratory experiments investigated the hydrodynamic differences between Amphibolis antarctica and Posidonia sinuosa, in terms of the bending behaviour of the plants under varying water flow regimes, and the degree of canopy compression as a result of bending.

本研究开展野外与室内控制实验，旨在探究水流速度对不同密度下南极海神草（Amphibolis antarctica）与波叶波喜荡（Posidonia sinuosa）的茎秆弯曲及冠层压缩的影响。本项目配套的水动力学研究，则聚焦于通过调控格里菲斯海神草（Amphibolis griffithii）草甸密度所引发的水流差异。

室内实验针对南极海神草与波叶波喜荡的水动力学特性差异展开研究，具体涵盖两种植物在不同水流工况下的弯曲行为，以及由弯曲作用导致的冠层压缩程度。
