Based on the general conception of holography, the author analyzes the tourism region with a holographic view of human - nature relationship, and considers, in the core, the origination, development, transformation of tourism region system is a course in which the resources system is transformed to the economic system ， to the cultural system, which demonstrates by the structure of tourism region objection system ? ? from the structure of tourism resources to the structure of tourism products ， to the structure of the tourism markets ， to the structure of tourism industries, and each step of transformation needs the input of anti - entropy from the subjection system ? ? the tourists, the tourism scholars, the tourism enterprising, the tourism media, the government and the local people who urge the region sustainable development. there are six chapters in the dissertation : in the first chapter, on the base of holographic view, the author constructs a holographic space which consists of one - dimensioned time, three - dimensioned space and multi - dimensioned system, which can supply for the study of variety and multi - perspective of tourism region subsystem, meanwhile originationable theory, fractal theory and down - to - the - earth theory are put forward as methodology, what ' s more, the author constructs the paradigm of the tourism region development as the frame of region tourism development. in the second chapter, with a holographic view, some concepts of tourism region system, both objection system and subjection system, are defined again, especially, the conception of tourism, tourist, tourism resources and tourism product, the author considers, it ' s only through information that can explain how the tourism derived and developed, what the tourist demands and utility are, and the relationship between the inner subjection system is regarded as mutuality

    本論文結構共分6個部分：第一部分，從全息學的基本觀點出發，構建出由一維時間、三維空間和多維系統組成的全息空間，這為研究旅遊地域各子系統的多樣性和多角度性提供了理論的依託，並將元化思考、分形理論和紮根理論作為旅遊地域開發的主要方法論，構建出旅遊地域全息開發的思維範式，為旅遊地域的開發奠定了堅實的理論框架；第二部分，從全息角度對旅遊地域系統，包括客體系統和主體系統，進行全新的界定，尤其對旅遊活動、旅遊者、旅遊資源及旅遊產品的概念進行全新界定，認為只有從信息角度才能理解旅遊活動產生、發展以及旅遊者的需求和效用，並在旅遊地域開發關繫上提出了互為主體的觀念；第三部分，從空間角度對旅遊地域進行分析，認為旅遊地域是運動的，要素運動形成要素的結構變化，進而推動整個旅遊地域的運動，同時，旅遊地域運動還受到環境系統的制約和影響，筆者還對旅遊地域相互作用關系作了較為深入的研究，認為不同等級間和同等級間旅遊地域相互作用遵循不同的規律；第四部分，通過對旅遊地域周期理論的再認識，詳細分析了影響旅遊周期的因素，並提出旅遊地域全息周期的理想模式是logistic曲線；第五部分，筆者對旅遊地域的開發模式進行了總結，從主體角度提出了4種旅遊地域全息開發模式? ?資源主導型、學者主導型、企業媒體主導型和政府大眾主導型，並從環境系統對旅遊地域開發的影響程度出發，提出2種修正模式? ?微阻礙模式和重阻礙模式；第六部分，以安西縣為例，在全息分析安西縣旅遊地域發展狀況之後，強調旅遊產品的開發與設計是旅遊地域開發的關鍵，並運用全息的觀點對旅遊產品開發進行了實證研究。
