The Effects Of The Regulation System On The Structure And Dynamics Of Green Space In An Urban Landscape

The effects of a regulation system on conserving the green space were evaluated in Kitakyushu City, southern Japan. Nearly half of the city is under the Urbanization Control Area that should restrain urbanization, and about 30% of the city is specified as Scenic Zones and Green Conservation Areas where their use is restricted by a regulation system. Area of green spaces within the Urbanization Control Area decreased slightly from 1984 to 2001, although those within Urbanization Promotion Area decreased largely. The specification for the Urbanization Control Area, therefore, plays a role in conserving area of green spaces. Specifying Scenic Zones as well as Green Conservation Areas also have value in retaining green spaces. Some woodland was, however, transferred to residential areas within the Green Conservation Area. This decrease in woodlands was due to constructing a City Planning Road, suggesting that area of green spaces even within a Green Conservation Area depends on decisions made by the municipalities. The habitat function of the forests for dominant canopy and sub-canopy evergreen broad-leaved trees was also evaluated by examining the relationships between stem densities at different growth stage (seedling, sapling and mature). Success of seedling recruitment of Castanopsis cuspidate (Fagaceae), for which the seed-dispersal type is classified as chasing dispersal, was depended largely on the existence of conspecific mature trees. Thus, the forests with a low density of conspecific matures have low habitat function for the species even if safe-sites for seedling recruitment exist. There were no clear relationships between densities at each growth stage for Persea thunbergii, Neolitsea sericea, and Cinnamomum japonicumof the family Lauraceae that the seed-dispersal type is classified as endozoochory. This finding might suggest that the habitat function of the forests for these three was not controlled by the ‘dispersal limitation’ as seen in Castanopsisbut by the micro-environmental conditions of the forests.
