Abstract：The process of urbanization has brought about a large number of construction of urban settlements, causing problems such as shortage of land resources and destruction of the natural environment. Therefore, the development of settlements in hilly areas has become an inevitable trend. The traditional settlement planning model in hilly areas often adopts "three connections and one leveling" and destroys the original ecological texture of the base for development. This has led to many environmental problems such as soil rock compaction, permeable system destruction, ecological vegetation destruction, and loss of water seepage capacity. The original natural surface runoff and landscape pattern characteristics of the hills were destroyed. This article is based on the concept of low-impact development, combined with the unique topography, hydrology, and human characteristics of hilly areas, and discusses hills from seven aspects: spatial layout, road system, rainwater system, sewage system, vertical design, sponge green space and architectural design. Regional settlement planning strategy system.
