Abstract
The purpose of this study was to analyze the characteristics of plant covering in the extensive green roof site. Eighteen herbaceous perennial grass such as Caryopteris incara and sedum species such as Sedum Kamtschaticum were planted on an experimental green roof with 10cm substrate depth in 2007. This study investigated vegetation change over 3 growing seasons 2007-2009. The covering rates of planted species mostly increased in 2008, but declined in 2009 except 6 species such as sedum specis and Thymus quinquecostatus var. japonica etc. There were four categories of covering characteristics generated from the results of this study. These include the type of sustain planting site, the type of encroach adjacent site, the type of creeps and spreads, and the type of scatters and spreads. The covering models of eight planted species were drawn by simple regression analysis. However more monitoring of various plants will be needed to establish the information for sustainable roof planting plan.
