Biological genes rely on the arrangement and combination of base pairs to store genetic information. Similarly, landscape genes store cultural information through an ordered structure of genetic information and express the characteristics of the landscape according to a specific transmission path. Based on the perspective of genetics, this article summarizes six pieces of genetic information—dominance, inheritance, attribution, attachment, scale, and image—from the connotation of landscape genes and conducts a case study of the heredity of cultural factors and the expression of the image in Zhongtian Village. The results show that:(1) The stone walls of buildings, the half-moon-shaped water, and the distinctive form of the geographical layout are the landscape genes of Zhongtian Village; (2) The genetic information can be used to examine the recognition results of landscape genes and eliminate interference items in the identification process, which is valuable in science; (3) The storage and expression of genetic information in the landscape genes of Zhongtian Village are also revealed in this study, which facilitates the production of a new means for the identification, inheritance, and tourism utilization of landscape genes. The study posits that landscape gene theory can play an active role in heritage tourism image construction, rural tourism planning, and cultural tourism landscape restoration.
