This study has been initiated to have question that as the Urban residential area that had been planned for land-use based on the Zoning has changed in the environment of residential and commercial areas while being mixed in the multiple purposes of the facility over time, unlike the purpose of the plan. Therefore, this study examined whether there is a difference between the 'plan' for the use of 'land' and the 'use' of 'facility' that is used by being actually constructed, and tries to investigate the reason for the change.
The analysis will firstly compare and understand the land-use plan of large population and the current facility purpose. Secondly, based on this contents, it will investigate the distribution and characteristics of the facility being used differently from the plan of land-use. Thirdly, by attempting to analyze the physical factors that these phenomena appeared, it will try to understand the interrelationship of urban functions. For the selection of study subject land, it selected 'Nonhyun-dong', and some parts of 'Chungdam-dong' and 'Samsung-dong' in Gangnam, which are Urban residential areas that its development purpose and intent of the plan are clear. Summarizing the contents of analysis, they are as follows.
C?characteristics of the functional change in urban residential areas are largely appeared as the commercialization of residential area, business use of residential area, and residentializing of commercial commercialization has been progressed when the width of the roads are wide, the number of the connection roads per unit length is less, and block's rows are high and slenderness ratio is less. In addition, when the size of land's plot is large and land's plot in corner, the commercialization index was high, it appeared different from the distribution of the neighboring commercial facilities and specialized commercial facilities. Meanwhile, business facilities in residential areas, depending on the size, showed different distribution tendency, and mostly distributed in the medium layers by being mixed with commercial facilities. Residential facilities showed in commercial lands, depending on the type of residential facilities, appeared differently in geographical conditions, urban transportation facility, and the position and slenderness ratio of the land's plot.
Zoning, through a number of modifications since its introduction, has changed into rather than the regulation of the application that specifies the function of lands, but as a regulation means for restricting the building-to-land ratio or floor-area to site ratio, and finally, this Zoning changes resulted in the commercialization of residential area, business use of residential area, and residentializing of commercial area. This tendency is different from the one that earlier Land-use plan with the purpose of use purification intended, and it can be seen that the use is mixed in all areas.
The reason that commercialization and business purpose change have occurred in residential areas, is because there was almost no difference of acceptable facilities, although segmentation has been made to residential areas, it just applied only the regulation of building-to-land ratio and floor area-to-site ratio. In addition, residentializing that could occur in the commercial areas has become to be located in the commercial areas depending on the form and the needs of residential facilities along with the trend of the times as a variety of residential facilities such as officetel, urban living housing, and boardinghouse have appeared.
To summarize this, although it has proceeded urban planning intended for use purification to urban residential areas in Seoul by using the land-use plan and zoning, it could be seen that facilities matching to the planned purpose are no longer located. That is, commercial facilities necessary for residential areas, or residential facilities required for commercial areas have been placed in the proper locations in order to fulfill the functions. As a result, the role of Zoning is playing a role in limiting the size such as the size and height of the buildings which are suitable depending on the purpose areas. Therefore, that the mixed of use rather than use purification by use separation is a natural phenomenon that takes place in the modern city, and facility-use is to be located by finding places that the building's scale and physical factors are appropriate, it could be seen.
This study has its significance of the study in that it presented a way of more sophisticated planning method by understanding how the purpose of urban planning has been distorted and deformed in the real world, and find its value in that provides the material that is able to plan desirable residential and commercial areas by forecasting the location of the facility-use in urban planning.
