Abstract: Taking Jiangwudian Village in Xi'an City as the research object and taking into account the conservation policy of the Great Heritage Relic Protection and related planning, the corrected axes were imported into Depthmap X software based on the theory of spatial syntax, and quantitative analysis was carried out on the connection value, integration, selection and comprehensibility. The results showed that the spatial permeability of Jiangwudian Village was weak due to the concentrated layout of houses and the villagers' focus on overall living and transportation; the villagers' daily travel was restricted due to the development of public transport, which resulted in a poor overall integration degree and a high local integration degree; the overall selection degree of the village was low, which had a great influence on the external reception potential of the village; the comprehensibility of villages was low, and it was difficult for outsiders to perceive and understand the structure of villages. The public service facilities of the village needed to be improved, the function of the spatial nodes of the village should be strengthened, a comfortable and pleasant local green space should be created in the context of the Great Heritage Relic Protection, and the accessibility and traffic guarantee function of the village should be improved, so as to provide a suitable spatial environment for the future development of the village.
