Traditional villages refer to the villages that formed earlier, are rich in traditional resources, and have various values and must be protected. This paper aims to study how to draw three-dimensional landscapes of traditional villages based on the big data information system. This paper puts forward the problem of 3D landscape rendering, which is based on big data and modeling, and then elaborates around the concept of data mining and related algorithms and designs and systematically tests 3D landscape rendering. The experimental results show that when the number of rendered patches is less than 120193 between 120193 and 242029, the system can run smoothly. It can achieve acceptable and relatively smooth operation; when it exceeds 242029, the system is obviously stuck. The design scheme of the three-dimensional landscape geographic information system of the traditional villages is reasonable and feasible, the operation is stable, and the expected research goals are achieved.

The local characteristic landscape is a way of adapting to nature, land, and land space pattern chosen by local people due to their living needs. With the in-depth development of the concept of ecological protection in China, great progress has been made in the cause of ecological environmental protection within the current urban area. This study mainly discusses the ecological effects of local materials in landscape design. It integrates geography, historical literature, landscape ecology, architectural aesthetics, and many other related disciplines. The basic knowledge of rural landscape elements is analyzed and summarized from all levels and angles. However, due to factors such as the contradiction between the urban and rural dual system, the large base of the rural population and construction land, the expansion of cities and the great changes in rural production and lifestyle, the rural living environment is faced with more ecological contradictions, which has become the bottleneck of the country’s overall ecological civilization construction. It comprehensively discusses and analyzes related concepts and theories, and optimizes the concept of rural landscape elements and the relationship between rural landscape elements and modern rural landscape design. It clarifies its classification and exemplifies the application methods of rural landscape elements. The second is to integrate and analyze the application of rural landscape elements through the investigation and analysis of excellent cases. It also compares the rural locality and studies the application of rural landscape elements and their shortcomings. Finally, the construction methods and application strategies of rural landscape elements in modern villages are proposed. Through the reasonable planning and configuration of the traditional village landscape, it creates a living landscape that can meet the actual needs of local people and an ornamental and experiential landscape that can meet the multilevel emotional needs of foreign tourists. This pushes traditional villages toward a benign path of sustainable development. The evaluation index of conformity between vernacular architecture and the environment reached 94%. On the basis of sorting out the problems of ecological planning and construction of rural human settlements, the article constructs the ecological adaptability theory of rural human settlement planning at the theoretical level. This study fully combines the advantages of local materials to build a beautiful village with regional cultural characteristics and ecological type, in order to open up new ideas for future rural planning and design.
