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.

Due to the impact of homogeneous construction, interrupted tourism investment, and population outflow, some traditional villages have become spaces where landscape standardization and landscape fragmentation coexist. This article takes the ancient town of Hekou in Lanzhou city, Gansu province as a case study, and uses the DFRI genetic theory and landscape genetic mutation model as the research basis. Starting with landscape genetic sequencing, participatory observation and semi-structured interviews were conducted to explore the mechanism of local landscape genetic variation since the construction of the ancient town project in 2014. The results show that: (1) Capital investment, elite behavior, and ideological changes can activate the response bases in the landscape genes, leading to changes in the base sequence. (2) Capital investment is the physical mechanism and external driving force for inducing landscape genetic variation. The spatial heterogeneity, non-sustainability, and purpose of capital investment in the ancient town project will affect the results of landscape genetic variation. (3) Elite groups driving village practices are the chemical mechanism and practical subjects for inducing landscape genetic variation, and rural governance, tourism development, and intangible cultural heritage inheritance led by the villagers committee and tourism companies can induce cultural landscape construction, improve villagers' quality, and change the livelihood patterns. (4) The change in ideology brought about by urbanization and social transformation is the biological mechanism and potential factor inducing landscape genetic variation. Urban culture, industrial transformation, and cultural evolution can insert into hidden segments of the landscape genes, thereby affecting the results of landscape genetic variation. Based on the analysis of the inducing mechanisms, this article proposes genetic optimization strategies for landscape standardization and fragmentation.

Landscape restoration serves as a pivotal means of promoting and disseminating traditional Chinese culture. In the New Era of rural digitalization, how to leverage digital empowerment in traditional village landscape restoration has emerged as a pressing scientific issue critical to facilitating the creative transformation and innovative development of traditional Chinese culture. By using in-depth interviews, GIS spatial analysis, point cloud data extraction and other methods, based on the connotation and characteristics of traditional village landscape restoration and the underlying structure of digital countryside, an analytical framework for the evolution of traditional village landscape restoration under the power of digital technology was constructed. In addition, taking Zhangguying village in Hunan province as a case study, the characteristics and driving mechanisms of its landscape restoration evolution under the power of digital technology have been explored. The research shows that: (1) The evolution of traditional village landscape restoration under the power of digital technology is to incorporate traditional village landscape restoration into the digital information network system, showing the process of integrating the physical space and virtual space of landscape restoration. (2) The evolution of landscape restoration in Zhangguying village exhibits the following characteristics: Streamlining of communication for landscape restoration objects, precision in the presentation of restoration subjects, virtualization of derived functions, and the overall integration of virtual and physical entities. (3) The mechanism of landscape restoration evolution features is the driving mechanism for the development of new tourism formats, which connects the development factors of information technology, the driving factors of digital policies, and the changing factors of consumer demand to the evolution of digital landscape restoration. The three factors are independent and interrelated, and they work together to form a multi-level driving mechanism. With the goal of promoting the excellent traditional Chinese culture, this paper explores the characteristics and mechanisms of the landscape restoration and evolution of traditional villages, under the aegis of digital technology. It aspires to furnish novel insights, methodologies, and avenues for the creative transformation and innovative advancement of the excellent traditional Chinese culture.
