Abstract: Traditional Chinese villages demonstrate remarkable resilience in coping with natural disasters and exhibit profound wisdom in adapting to climate and managing rainwater. Based on the characteristics of karst landforms in Guizhou, this study selects Benzhai Village in Qiyanqiao Town, Xixiu District, Anshun City, Guizhou Province as the research object. Using SWMM software, it conducts an in-depth analysis and research on the water management patterns of the village from three levels: village site selection and spatial layout, street and alley spaces, and architectural units. The results show that when facing rainfall return periods of 1year, 5years, 10years, 20years, and 50 years, Benzhai Village has a relatively low total infiltration volume, with a runoff coefficient ranging from 0.991 to 0.997. The maximum flow rate and the ratio of the maximum depth to the full-flow depth reach a maximum of only 0.056, reflecting the village's good drainage capacity. This study aims to summarize the wisdom and experience of traditional villages in water management, with the hope of providing valuable references for future ecological governance and sustainable development in karst regions.
