 note = {本研究はチョウ類群集の存在･不在2元データ(binary data)を利用して, クラスター分析と数量化IV類による環境評価を試みたものである. 香川県にある9つの環境保全地域, 1つの町立森林公園および県立自然公園内の3地域で, 1992年から1996年の間に採集と目視による調査を行い, 生息チョウ類の目録が作成された. 調査した13地域で確認できたチョウ類は, 8科74種であった. 調査地域の平均標高および面積と種数との間には明瞭な相関関係は見られなかった. 目録は存在･不在の2元データなので, SφrensenのCs係数を1から減じた1-Cs係数と不一致係数(いずれか一方の地域で確認された種数/全調査地域で確認された種数)を, 種構成の重複度を表す非類似度行列として多変量解析をおこなった. クラスター分析と数量化IV類のいずれの手法でも, 13の調査地域は3つのグループに分類することができ, グループの構成地域もほぼ同じ結果であった. 調査地域の植生と多変量解析による分類結果を比戟して, 本評価手法の妥当性を検討した., An approach to evaluate the environment using cluster analysis and quantification theory type IV based on the binary data of a butterfly community was tried. The investigation to make an inventory of butterflies was done at 9 environment preservation areas, one forest park, and 3 survey areas in the natural parks in Kagawa Prefecture from 1992 to 1996 by collecting and observation methods. The number of butterfly species found in this investigation was 74 species belonging to 8 families. The number of species found in each survey area was not related to either the altitude or the area. The Sφrensen coefficient (Cs) and disagreement coefficient (the number of species found in either area)/(the number of all species found in 13 survey areas) was used to compare the community composition between 2 areas by the number of species. Thirteen survey areas were classified into three groups by cluster analysis using the dissimilarity matrix of the 1-Cs coefficient and disagreement coefficient. The grouping by quantification theory type IV agreed with the result of cluster analysis. The validity of application of these multivariate analyses for the structural analysis of butterfly communities is discussed by comparing with the grouping from the flora of survey areas., Article, 環動昆 12(2): 77-89 (2001)},
