Different from the low sustainability of modern disaster prevention strategies based on engineering facilities, the soil resource disaster prevention strategies of pit courtyard villages have a history of thousands of years of application and are a manifestation of truly high sustainability. As the most accessible and inexhaustible building material, soil resources are widely used in the disaster prevention construction of pit courtyard villages maintained and supported by loess. As a fresh carrier of soil resources disaster prevention wisdom, the characteristics of low technology, low cost, low maintenance and high sustainability of the soil resources disaster prevention strategy in the pit courtyard village are the important reasons why it is still in effective operation after thousands of years. Based on the conclusion that flood and drought are the main disasters in pit courtyard villages, this paper takes Baishe village as an example to conduct qualitative and quantitative research from three aspects of village layout pattern, village underlying surface composition, disaster prevention system and facilities, and calculate the data of off-season and local use of rainwater. The results show that under the influence of land resources disaster prevention strategies such as the layout of villages based on terrain, the layout of disaster prevention facilities that conform to the height difference, and the application of disaster prevention materials based on the characteristics of soil resources, the proportion of rainwater in Baishe Village is 65 %, which is similar to the requirements for sponge city construction (70%), and is an effective strategy to deal with droughts and floods. Finally, through the summary and condensing of its land resources disaster prevention strategies, it is expected to provide inspiration and reference for modern rural planning and layout, disaster prevention facilities construction, and disaster prevention construction materials application.
