Research Abstract

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.
