서울시 주택재개발·재건축사업 정비예정구역의 주거환경평가

서울시 재개발·재건축 정비예정구역의 주거환경을 평가했다.

Recently, the seoul metropolitan government announced the planned management of residential areas that expanded from the residence environment improvement project(housing redevelopment project, housing reconstruction project, and housing improvement project)'s individual scale lacking of connectivity with surrounding as promoted by individual regions to the those wide scale of living area. The existing residential environment improvement project was in a progress in individual regions after being designated districts for the residence environment improvement project through the small physical standard to improve the residential environment of deteriorated existing urban areas.

But it was not considered the connectivity with surrounding. Because the districts for residence environment improvement project were designated through the small standard evaluating the physical environment. And it was not clear whether the residential environment of designated districts was poorer than that of non-designated districts. In principles the residential environment is the physical-social condition and the residential areas' function influencing residential life. And the environment improvement is to improve to the advanced state by improving or mending the physical-social condition, maintaining the function.

But the existing residential environment improvement project was considered the physical residential environment that means the household density, the degree of superannuation of buildings, the ratio of approached street, and the ratio of underestimated parcels. Therefore it is not expected that the residential environment improvement project can improve the social-economic residential environment. And it is raised the matching problem whether the districts for residence environment improvement project were properly designated through the small standard evaluating the physical environment. For example, some districts are the house area having the good residential environment.

Therefore it is necessary that we seize the level of their residential environment through the evaluation on the residential environment of districts for residence environment improvement project and watch whether those were properly designated or not. This study tries to judge whether those were properly designated or not by evaluating on the residential environment of the districts designated through the small standard evaluating the physical environment for residential environment improvement project.

This study is trying to need to convert to residential environment indicator to meet the original purpose of residence environment improvement project by pointing out the limitations on designating the districts for residential environment improvement project through the small standard evaluating the physical environment. And this study confirms problems of the existing residential environment improvement project lacking of connectivity with surrounding by confirming geographical homogeneous and continuous character through analyzing spatial autocorrelation.

And this study intends to clarify the necessity regarding the geographical homogeneous and continuous character of residential environment at the planned management of residential areas. The results of this study are as follows. First, this study divides the entire of Seoul City into polygon of the same size based on , minimum area of districts for housing redevelopment. And this study evaluates residential environment based on safety, healthy, convenience, amenity, sustainability of each polygon and evaluates total residential environment by uniting each result.

As a result, the aspect of residential environment(residential environment based on safety, healthy, convenience, amenity, sustainability and total residential environment) is appeared variously. For example, the residential environment in urban areas is convenient, not pleasant and not healthy But the residential environment in the outskirts of city center is contrary. Next, this study analyzes spatial autocorrelation targeting polygon evaluated residential environment and verifies the geographical homogeneous and continuous character of residential environment.

Therefore the geographical homogeneous and continuous character of residential environment will be considered at the planned management of residential areas. Last, this study analyzes whether those were properly designated or not by evaluating on the residential environment of districts for housing redevelopment project and housing reconstruction project. As a result, the residential environment of 139 districts(housing reconstruction project:122 , housing redevelopment project:17) among districts for housing redevelopment project and housing reconstruction project is good.

And this study can confirm matching problem by topic(safety, healthy, convenience, amenity, sustainability) by ploting the type. Thus by the result of designating districts by the small standard evaluating the narrow viwpoint's residential environment, the areas having the good residential environment were included. The residential environment mentioning at housing redevelopment project and housing reconstruction project does not mean the only physical residential environment. But the existing specific conditions designating districts only evaluate the physical state.

Therefore the existing specific conditions can't the actual residential environment and so we need to convert to residential environment indicator to meet the original purpose of residential environment improvement project. This study collects residential environment indicator at preceding research, literatures. And the residential environment indicator is chosen by the possibility of data acquisition, the possibility of analysis, and researcher's subjective judgement. Each indicator evaluates the residential environment at the time of researching. In the past, the residential environment was evaluated through 4 evaluati
