In the context of global climate change, extreme weather is frequent, and ecological water management has gradually become a hot topic of research and attention in recent years. Nowadays, most traditional villages have formed a relatively complete ecological water governance system, so exploring the ecosophy contained in the traditional village water governance system is particularly important. This paper takes the rainfall changes in Beiliu, Guangxi as the research background, ecological wisdom as the theoretical basis. It uses ArcGIS spatial analysis to explore the ecological wisdom of water management in the village of Yalang Village, Beiliu, Guangxi, at three levels: macroscopic, mesoscopic, and microscopic: (1) the wisdom of siting the village according to local conditions, (2) the wisdom of building the village according to the water, (3) the wisdom of the drainage and storage system to protect the water and summarise the principles of ecological water management in Yalang Village, which will provide a useful reference for future traditional villages to deal with flood prevention, ecological restoration and sustainable development of rural industries.
