Artificial floating islands offer comprehensive functions, including water quality purification, creating habitats for wildlife, landscape enhancement, and wave attenuation. They are widely used in reservoirs with significant water level fluctuations, lakes where it's challenging to restore shoreline aquatic vegetation due to waves, and ponds with landscape requirements. As the number of artificial floating island projects increases, so does the accumulated experience, leading to a shift from qualitative to quantitative evaluations in assessing their functions and effectiveness.
