The purpose of this study is to clarify the relationship between the distribution of small-scale green spaces and the butterfly assemblages in urbanizing area located at the north-east of Ichikawa city. As an indices of ecological gradient by the distribution of urban green covers (over 2m2), GCI (Green Cluster Index) of each vegetation type, co-occurrence of the different vegetation types, distance from each vegetation type, and diversity index of vegetation were calculated by using high-resolution aerial photograph image. As a result of analysis on the relationship between butterfly assemblages in each survey root units and the indices around them, using Classification and Regression Trees, it was clarified that distribution of deciduous trees in large scale area and small-scale mosaics of vegetations in its surrounding area are important factors for the width of butterfly assemblages.
