Abstract
Recently, it is required to investigate the distribution of vegetation-covered areas on a regional scale for not only the improvement of urban environment but also the conservation of ecosystem. The spatial continuity of vegetation-covered areas like green corridor plays an important role for the preservation of ecological balance especially. For the analysis of the spatial distribution of vegetation-covered areas on a regional scale, we defined the NDVI calculated from Landsat ETM+ data as the potential of the existence of vegetation-covered areas, and applied them to the analysis using local spatial autocorrelation. The areas that showed the strong spatial autocorrelation from a narrow range to a wide range were interpreted as high-potential areas on the spatial continuity of vegetation-covered areas. The new map of spatial scale of clumping vegetation-covered areas, which presented contour lines based on fluctuations in the number of the range of the strong spatial autocorrelation, was proposed.
