Abstract: Taking the landscape system of Pingyao Ancient City in Shanxi Province as the research object, the landscape genes of Pingyao Ancient City were identified and extracted from the four aspects of environment, layout, architecture and culture with the help of landscape gene theory, and were quantitatively sequenced by AHP(Analytic Hierarchy Process)-FCE(fuzzy comprehensive evaluation method) to construct the landscape gene sequencing index system of Pingyao Ancient City and make clear the application of landscape factors in the enhancement of ancient city landscape style. The results showed that the comprehensive evaluation score of Pingyao Ancient city was 3.374 1 points, and the overall landscape genes’ evaluation was good. The comprehensive scores of the criterion layer, from high to low, were layout gene, architectural gene, environmental gene and cultural gene, indicating that the layout gene and architectural gene of the ancient city were good, while the environmental gene and cultural gene needed to be improved. The analysis index layer showed that six landscape genes, namely water system environment, green landscape, religious belief, local culture, traditional skills and folk art, could be effectively used in the landscape enhancement of Pingyao Ancient City.
