We investigated a flora and vegetation on the coastal Ryukyu limestone, properties of bedrock, planting method of appropriate plant, scenery and present roof greening situation in Okinawa for developing a roof greening technology to moderate heat island phenomenon. The plants were classified into five groups considering life form, and they were also classified into five groups considering dominance/group degree through functionality and characteristics for practical uses. The base soil derived from limestone contains calcium, and the soil properties were strongly influenced by the vegetation. Among different species, Zoysia matrella var. pacifica showed a small growth difference between seasons, and the whole surface greening was more effective in temperature relaxation. A general study including the views and the sensory of human beings for the roof greening is expected in future.

为了开发缓和热岛现象的屋顶绿化技术，调查了琉球海岸石灰岩的植物群和植被、基岩的性质、适宜植物的种植方法、风景和冲绳的屋顶绿化现状。根据生活型将植物分为五组，根据功能和实际用途的特征将它们分为五组，考虑优势/组度。石灰岩基土含钙，土壤性状受植被影响很大。不同种间，沟叶结缕草（Zoysia matrella var. pacifica在不同季节的生长差异较小，全表面绿化对温度的缓和效果更好。希望将来能对屋顶绿化进行全面的研究，包括人的视觉和感觉。
