高頻度使用語に着目した景観形成基準の構造的特徴の分析

摘要

現在，多くの都市で景観法に基づく景観計画が策定されている．そのなかでは，これまでの自主条例による景観形成基準の見直しが行われ，これまでとは制度的背景の異なる景観形成基準が市街地に適用されている．　景観法制定前の自主条例としての景観条例（以下，自主条例という．）による景観形成基準と，景観法による景観計画として定められた景観形成基準とでは，そのあり方も異なってくるものと考えられる．%Making rules on urban design has become more important to sustain good townscape. This paper deals with townscape control standards which were made before Landscape Act was established. It is intended to identify what words are frequently used in townscape control standards, using morphological analysis and word frequency analysis, and why these words are extracted. These two analyses have extracted thirty words which are frequently used in townscape control standards. It has been found that three words, "Tsutomeru", "Hairyo" and "Chowa" reflect characteristics of autonomous townscape ordinance. From the results of dual scaling it is shown that "Tsutomeru" is correlated with townscape control standards on space use, and "Hairyo" and "Chowa" are correlated with townscape control standards on exterior design.
