In recent years,with the comprehensive development of the state’s inheritance and protection of intangible cultural heritage,the Yao long drum dance,as an intangible cultural inheritance event with distinctive ethnic and regional characteristics,has also realized the survival and development of culture with the help of national policies.However,the early research on the long drum dance of the Yao ethnic group focused on its artistic pursuit,but the cultural carrier function of the long drum dance was gradually separated from the inherent cultural ecological space.With the change of cultural ecology,the original social structure of the Yao long drum has undergone qualitative changes.In the context of cultural pluralism and harmonious development,the normality of the cultural change of the Yao long drum makes the dynamic protection meaningful,and the integrity of cultural protection makes the ecological analysis inevitable.So,how to retain the cultural connotation of traditional intangible cultural heritage without losing ethnic color and humanistic feelings? This is the theoretical analysis and practical problem that the author needs to study and discuss next.Therefore,starting from the research from the perspective of cultural ecology,a hot spot in the recent protection of intangible cultural heritage,the team spent six years,visited more than 20 Yao villages in Jianghua,Guangdong and Guangxi,collected more than 500 books and documents,and recorded more than 200 images,audio and video materials.Through diachronic analysis,this paper expounds how the cultural phenomenon of Yao long drum dance adapts,changes and develops in the whole process of cultural ecological change brought by the impact of specific social ecological environment,and tries to understand how to maintain the stability and harmony of the internal and external ecological space of the main culture in the specific cultural ecological space.It also guides the exploration of design theory with the theory of cultural ecology.As an analytical model for the theoretical research of regenerative design of intangible cultural heritage,it borrows its research framework by using the theories and methodologies of cultural ecology,cultural philosophy,semiotics and psychology.The ideological base point of "Tao,law and art" in traditional cultural philosophy and the two axes of regenerative design provide the groundwork of "art" for the exploration of "Tao" in design ecology,Then re-examine the systematicness of design culture and the "ecological balance" between culture and social development.Carried out design practice activities jointly by multiple political schools,integrated various resources of "political science research and application",introduced the regenerative design model into the regional cultural ecosystem,verified the linkage effect of the cultural ecosystem combined with design cases,and summarized the practical methods and research value of regenerative design based on the cultural ecological background,in order to provide practical path reference for the protection and inheritance of intangible cultural heritage. |
