DEVELOPMENT OF THE SPATIAL ANALYSIS METHOD OF VEGETATION DISTRIBUTION FOR THE PURPOSE OF SUPPORTING PRELIMINARY ASSESSMENT ON A REGIONAL SCALE

Abstract

Recently, it is required to investigate the spatial distribution of vegetation in urban areas on a regional scale for not only the improvement of urban environment but also the conservation of ecosystem. The purpose of this study is to develop the analysis method of the spatial distribution of vegetation on a regional scale. We defined the NDVI calculated from Landsat ETM+ data as the potential of vegetation abundance. The spatial analysis method consisted of local spatial autocorrelation and hydrological analysis for extracting the core of the vegetation-covered areas and uncovered areas, and the two kinds of lines regarding the spatial continuity of vegetation distribution.
