The pattern of urban spatial

There are several theories about the spatial patterns of cities:1. The theory of concentricThe theory was developed by Ernest W. Burgess who examined the city of Chicago. According to this theory the pattern of land use in the city following the zones of concentric circles (circular). The structure of land use are grouped into six concentric zones, namely:a. Zone Regional Activity Centre (PDK)PDK territory or in a foreign language Central Business District (CBD) is the central urban areas characterized by buildings, shopping centers, post offices, banks, cinemas, markets, etc..b. Transition zone (transitional)This area is the area of ​​manufacturing, light factories and respected community residences.c. Zone low-income housing communitiesThis area is home to a small workers.d. Middle income residential zoneThis zone is a middle-income residential areas such as civil servants, military, merchants, etc..e. Zone elite residential communityThis zone is characterized by the area inhabited by the elite rich people like executives, businessmen and officials.f. Zone commuter (suburban)Zone is characterized by the presence of the commuters (commuters) who work in the city during the evening but back home in the suburbs.
2. Theory sectoralSectoral theory proposed by Homer Hoyt. He argues that land use patterns in cities tend to develop following sectors are more free than by concentric circles.The existence of sectoral usage patterns shaped elongated shape caused the land and road development as a means of communication and transport routes. This is due to location of human settlements tend to follow the path of the road.
3. Core Theory of MultipleThis theory was put forward by C.D. Harris and E.L. Ullman. This theory is actually a critique of the theory of concentric and sectoral theory. According to this theory the development of the city is not growing like concentric and sectoral theory because in the city there are certain places that serve as the core of the city as industrial areas, ports and road networks, complex universities, etc.. In the sense that the center of not one, but multiple.
