The scale of the artificial floating islands is different for different purposes. The results of the study show that at least 1,000 square meters are required to provide a habitat for birds. If the purpose is to purify water, in addition to small pools, experts believe that it is necessary to cover 30% of the water surface. If the main purpose is landscape, it should be at least The viewing angle is 10°～20°.
Wave suppression effect, which protects the shore.
1) Because of the higher water exchange capacity, the effect of preventing water pollution in the dike is greater.
2) Even in deep water areas, the construction cost is lower than that of a fixed breakwater.
3) It has nothing to do with the quality of the underwater foundation. Even if it is installed on a weak foundation, it does not require foundation treatment.
4) Easy to change the installation location.
5) Short construction period on site. In addition to the above-mentioned advantages, the floating island used for wave protection has better compatibility with the vegetation belt on the shore than other wave protection structures.
