Traditional settlements are important material carriers of Chinese history and culture. After hundreds of years of development, the traditional settlements have survived until now, and the bottom-up construction mode reflects the most direct and original demands of the aborigines of all generations. The degree of disorder of the settlement, that is, the degree of its order, is not only the embodiment of its form, but also the concrete manifestation of its construction intention. To explore the intention behind the construction of settlements since ancient times.By using Delaunay triangulation network, street polar histogram and direction entropy, and comprehensibility of settlements, this paper quantitatively analyzes the degree of disorder in the three levels of architecture, street and local environment of the settlement. The paper, combining the background of the settlement, analyzes and compares the causes of the degree of disorder in the three levels of point, line and plane, and then explores the construction ideas of our ancestors for the settlement, so as to provide a scientific basis for the future planning of the settlements.Discovering the inherent construction principles within traditional settlements helps them maintain relative stability under external interventions. The results of disorder degree analysis serve as a benchmark for future settlement planning, contributing to the scientific basis of future decision-making.
