The protection and utilization of traditional villages is not only a major practical issue to realize China's rural revitalization and Chinese-style modernization, but also a hot topic in the integration and cross-research of geography, sociology, planning, economics and other disciplines. In order to systematically explore the theoretical cognition, practical problems, system mechanism, practical experience and effective path of the protection and utilization of traditional villages in China, 11 experts in the research field of traditional villages were invited to conduct interviews. The interview mainly focuses on the classification of Chinese traditional villages from three perspectives: policy change and typical model, macro mechanism and core theme, theoretical cognition and practical path, and focuses on specific practices such as industrial integration, landscape protection, vitality, value realization, subject drive, spatial governance and locality, based on the theoretical understanding of the macro system and mechanism for the protection and utilization of Chinese traditional villages. Advanced theoretical and practical issues such as industrial integration, landscape protection, organic renewal, vitality, value realization, subject drive, spatial governance and locality were discussed in depth. According to the main views of the experts, the protection and utilization of China's traditional villages in the new era should focus on: (1) The main problems of protection and utilization of Chinese traditional villages facing the impact of rapid urbanization and modernization, the innovation of mechanism and system, and the realization path. In view of the conflict between modern civilization and agricultural civilization faced by traditional Chinese villages and the major strategic needs for national rural revitalization and Chinese-style modernization, the combination of "top-down" and "bottom-up" is adopted to build a diversified integration mechanism featuring multi-subject participation, organic integration of agriculture, culture and tourism, and overall coordination. By exploring the endogenous growth factors of traditional villages and the historical inheritance and cultural context of traditional villages, strengthening the leadership of rural grassroots party building, giving play to the role of villagers as the main body, reshaping the public cultural space system of traditional villages and all-round digital twin modeling, etc., we will create a living environment that is in line with modernization development and ecological civilization construction and jointly build a cultural map, to realize the transformation of traditional Chinese villages from "vegetable gardens" and "back gardens" to "spiritual homes". (2) Core themes and specific spatial practices of protection and utilization of traditional Chinese villages for rural revitalization and Chinese-style modernization. Focus on the core themes of traditional village classification, industrial integration, organic renewal, landscape protection, vitality, value realization, subject drive, spatial governance and local reconstruction, and strengthen the classification and classification of traditional villages based on the coupling of key factors such as "livelihood, water, food, energy and land"; focus on the significance, connotation and influence mechanism of the time dimension, space dimension and attribute dimension of traditional village industrial transformation; focus on the three tasks of "protection and development countermeasures, measures to improve people's livelihood, and strategies to activate utilization" to promote the organic renewal of traditional settlements; emphasis should be placed on the gene protection and inner spiritual value mining of traditional human settlement cultural landscape, the "living" protection and utilization of traditional living space and the "activation" of traditional cultural heritage; focus on the diversification of traditional village activities, "co-construction, co-governance and sharing" and the construction of beautiful villages; the importance of natural non-human elements and human beings as spatial order construction and place construction of traditional villages and their active practice are emphasized to promote the realization of multi-functionality and multi-value of traditional villages. Pay attention to the excavation of traditional cultural heritage and intensive and efficient material space, create a harmonious and comfortable social space and protect and inherit traditional culture space; focusing on rural elements such as "ecology, culture, subject, and industry", strengthening ecological background, inheriting and developing local culture, balancing capital advantages and local embeddedness among local and cross-local subjects, so as to realize local reconstruction and characteristic remodeling of traditional Chinese villages.

The study of cultural landscape genes of traditional villages is one of the key areas of geography, which plays an important role in the inheriting China's outstanding culture, protecting countryside characteristic features, and supporting rural revitalization. Taking the Tanka Fishing village in Lingshui Li autonomous county, Hainan province as an example, this paper established an analysis framework of cultural landscape genetic for the Tanka Fishing village based on the Landscape Gene Theory, identified and analyzed its types, characteristics and information chain of cultural landscape gene of the village. The results show that: (1) The Tanka Fishing village has abundant cultural landscape genetic types. Material culture landscape gene can be divided into two parts: sea and land, reflecting the historical changes of the production and lifestyles of the Tanka people; The intangible cultural landscape genes include traditional skills, music, language, etc., which implicate the good wishes for happiness, peace, and harvest of the Tanka people. (2) The intangible landscape gene information elements such as traditional skills, language, music, customs, and festivals fully reflect the landscape features of "fishery production and lifestyle" and distinctive marine "fishing culture" as the core of the Tanka Fishing village. It is difficult for material cultural landscape gene to fully reflect the meta-characteristics of landscape gene information with the development of society, but the gene can still be mined from the plane structure and local decoration. (3) Important landscape gene information points such as ancient pier, Sanjiang Temple, traditional folk on land and marine fishing rows in Tanka Fishing village showed diversified functions. Sea and land landscape gene information corridors are important channels connecting landscape gene points in the village, which has an obvious character of hierarchy. The characteristics of landscape gene information network are obviously intensive, the layout of fishing rows at sea is regular and large, and the traditional buildings on land are scattered.
