Residential land nature of structural changes is the change in the social structure of residential land on the spatial distribution of specific performance. Under the background of the rapid urbanization, fevelopment of National Tourist Resort also presented the phenomenon of urbanization and promoted its interior spatial variation of the formation of residential land.
