《周易圖》為多元輯收之圖說《易》著，機械化的圖式結構背後，反映出龐博蘊奧的思想內涵，妙司神契，造微詣遠，多有可考索探析之處。以圖式模式建構卦變之說，乃至以卦變主張作為易學之重要論述觀點，為宋代易學關注的普遍現象，《周易圖》中亦廣取諸卦變之圖式，故本文專取與卦變有關之圖式，作為探述之主要論題。《周易圖》輯制之卦變圖說，包括〈序卦圖〉、〈雜卦圖〉、〈八卦推六十四卦圖〉、〈乾坤交成六十四卦圖〉、〈八卦生六十四卦圖〉、〈李氏六卦生六十四卦〉、〈乾坤大父母圖〉、〈復姤小父母圖〉、〈八卦司化圖〉、〈十有八變成卦圖〉等圖式。透過檢索有關圖式，進行各卦變之說的主要模式與具體內涵之理解分析，同時確立宋《易》圖說於此發展之重要關注取向與傳衍系譜。

Zhouyitu is a wide collection of Yi-diagrams. Behind the mechanical structures of Yi-diagrams, a rich and profound philosophy is worthy of exploration and analysis. It is a common practice for Yi philosophers in Song Dynasty to formulate Gua-bian theories through different diagram patterns, and then focus on the development of arguments based on their views of Gua-bian. And Zhouyitu is no exception. Thus the present study focuses mainly on the investigation of Yi-diagrams related to Gua-bian in Zhouyitu. Gua-bian Tu-shuo collected in Zhouyitu include: ＂Xu-gua-tu,＂ ＂Ba-gua-tui-64-gua-tu,＂ ＂Qian-kunjiao- cheng-64-gua-tu,＂ ＂Ba-gua-sheng-64-gua-tu,＂ ＂Li-shi-6-gua-sheng-64-gua,＂ ＂Qian-kun-da-fu-mu-tu,＂ ＂Fu-gou-xiao-fu-mu-tu,＂ ＂Ba-gua-si-hua-tu,＂ ＂Shi-youba- bian-cheng-gua-tu.＂ By examining the relevant diagrams, this paper aims to provide a comprehensive and detailed analysis of the major patterns of Gua-bian theories, clarify the significance of the development of Yi Tu-shuo in Song Dynasty, and establish the potential inheritance relationships among these diagrams.
