For the purpose of recycling of waste glass fiber reinforced plastic(GFRP) and easing of heat island phenomenon, authors have previously proposed a greening plant that moss was planted on ceramic base made from clay and waste GFRP. In this study, the improvement of wind resistance performance of the ceramic base planted with moss was attempted by arranging indents on the surface of the ceramic base. Firstly, for the some ceramic bases which arranged indents of the dimension which differs on the surface, the flow of wind on the base surface was analyzed using FEM. From the FEM results, it was shown that wind resistance performance of a ceramic base with the indents consist of diameter 12mm and depth 4mm was superior to that of other ceramic bases. Secondly, wind resistance tests of the ceramic bases planted with moss were carried out and it was confirmed that for the ceramic base with good wind resistance performance obtained from the FEM results, the quantity of the moss that has been separated from the ceramic base was very small. From the above, it was clarified that wind resistance performance of greening plant with moss by arranging indents of the suitable shape on the surface of the ceramic base was improved.
