The formation and development of settlements are closely related to the natural and social environment where they are located. Settlement adaptation refers to the adjustments that local residents make with their settlement to respond to the changes, either predicted or unexpected, of both the natural and social environments. It is a reaction of humans to make human settlements adaptable to the specific situations of topography, climate, demography, culture, economy, etc., which may take place at different levels from region to building, such as the settlement location in view of geographical and landscape patterns, the functional layout in view of social needs and terrain limitations, the architectural program in view of living style, climate conditions, etc.
