摘要：The purpose of this study is to clarify the relationship between the distribution of small-scale green spaces and butterflyassemblages in urbanizing areas located north-east of Ichikawa City. Landscape indices of green cover distribution with a diversityindex H of vegetation types and a number of different vegetation types, GCI (Green Cluster Index) of each vegetation type andaverage minimum distance from each vegetation type were calculated in different ranges from survey root units, using highresolutiongreen cover data made by object-based classification of Quickbird multi-spectral image. Analyses on the relationshipbetween the richness (number of species, Shannon-Weaver’s H’ and combination of species types) of butterfly species in survey rootunits and the landscape indices around them, were executed by using Classification and Regression Trees (CART). The forest(interior) species were thought to be appropriate indicators of the width of butterfly assemblages, and the gathering of evergreenwoods, deciduous woods and bamboo groves in small range guaranteed by the large-scale mosaic of those green covers werethought to be influential on their existence in the study area.
