The purpose of the present study intends to evaluate impacts of high-speed rail transit on population distribution in Korea. Does the initiation of the transit result in the population dispersion from such developed regions as Seoul or Busan? Does construction of high-speed rail transit lead to the reduced regional disparities in terms of population distribution? To answer these questions, we construct a spatial econometric model and simulation analyses are carried out for two alternative hypothetical scenarios of the rapid rail transit network of which the first step will be initiated in April, 2004 and the completion of the transit will be made in 2010. We found that cities linked to the rapid rail corridor have population gains, however, other regions remoted from the corridor expected to lose the net migration. The loss is predicted to be particularly serious for KangWon and Northern Jolla that are far distant from the main corridor. We also found that rural areas in all regions will be losers in net population migration. The present study concludes with suggesting some policy implications that may alleviate the disparities caused by the rapid rail transit.
This study intends to find out and analyze the designation of floor area ratio, the extent of satisfaction of the floor area ratio and the determinants of floor area ratio in the old city center and the new city center in Busan, Korea. In addition, it also aims to clarify influences of some factors on the extent to which the floor area ratio is fulfilled.
The results of this study are summarized as follows.
1) Among buildings in the new city center of Busan, the highest realization ratio (0.61) was obtained from those built with an average floor area realization ratio of 0.51 and a legal floor area ratio of 1100 percent. In case of the old city center, the buildings with an average floor area realization ratio of 0.58 and a legal floor area ratio of 800 percent showed the highest realization ratio (0.61).
2) In the new city center, the item of front-road width has the greatest influence on the floor area realization ratio the width of front road. As the category score for the front road width (026 meters) shows a positive value, the category is considered as contributing to increasing the average of realization ratios.
3) For the size of site, posted land prices and ownership, the items have different influence in the new city center and the old city center.
4) In the planning of reviewing or resetting of floor area ratio, considered as the influencing factors on the realization ratio should be the front road width, the using purpose of buildings and posted land prices in the new city center, and the front road width, posted land prices and the size of site in the old city center.
It is necessary for National Geographic Information Clearinghouse to provide service of more various geographic information utilizing the private sector investment and creative mind in production and circulation of geographic information. In this study, we suggested participation method that the private sector cooperates with the public.
The shape of participation that the private sector participates to National Geographic Information Clearinghouse must become method that the private sector cooperates together with the public than concept of under private management that entrust some function to the private sector. On the assumption that the private sector can have complementary relationship to the public, in this study, we suggested participation method by role division of the public and the private sector. Through the role division by each forte can grow up, the importance of cooperation between the public and the private sector will be increased. If the role division will be achieved, participation effect of the public and the private sector can be maximized.
서울시를 대상으로 도시 비오톱의 서식특성을 분석하기 위해 대상지를 정주지 비오톱과 산림지 비오톱으로 구분하여 서식지 특성에 따른 조류다양성 변화를 살펴보았다. 이들의 구분은 불투수포장비율과 인간의 간섭정도에 따라 구분하였다. 정주지 비오톱(n=35)에서 18종의 조류가 관찰되었으며 전체면적은 157.01ha이다. 또한, 산림지 비오톱(n=39)은 23종의 조류가 관찰되었으며 전체면적은 135.96ha이다. 전체 대상지에서 전반적으로 참새와 까치 등 도심에서 흔히 접할 수 있는 조류의 출현빈도가 높게 나타났다. 특히 정주지 비오톱에서 도심성 조류의 출현빈도가 높았으며 수동에 서식하는 딱다구리와 산림성 조류인 노랑허리솔새, 오목눈이, 꾀꼬리 등은 산림지 비오톱에서만 관찰되었다. 종-면적 축적곡선을 살펴보면 산림지 비오톱이 정주지 비오톱보다 조류의 증가율이 높게 나타났다. 그리고 서식지 크기에 따른 조류다양성의 변화를 살펴보면, 대부분의 조류들이 1-10ha에서 관찰되었다. 이렇듯 불투수포장비율이 높은 비오톱에서 조류다양성이 낮게 나타났으며 이를 보안하기위해 정주지 비오톱 및 작은 면적의 서식지를 중심으로 도시지역에서 조류의 다양성 증진을 위해 비오톱 네트워크화가 요구되어진다. 또한 도심 내에서 조류다양성 증가를 위해 각 대상지의 수직적 경관구조의 다양성이 요구되어지며 정주지 비오톱을 징검돌로 활용하는 방안이 마련되어져야 할 것이다.
This study shows how the urbanization of the Seoul Metropolitan Region(SMR) has progressed for the last 30 years and what its characteristics are. So far, the urbanization of the SMR has been analyzed through societal and economic indicators or statistical data. Here, however, the urbanization of the SMR is analyzed in the aspect of urban planning that places more emphasis on the spatial relation. More specifically, this study examines the urbanization of the SMR from the land use changes, accompanying to the urbanization, and the spread process and characteristics of the urbanized area.
In order to analyze the dynamic urbanization process of the SMR effectively, here, remote sensing and GIS techniques are used. The satellite images used are Landsat MSS and TM, which are a total of six from 1973 to 2000 for time series analysis.
The urbanization of the SMR began to expand to the satellite cities adjacent to Seoul in 1980s. The rapid expansion of urbanization has reached a climax with the construction of five new cities in the SMR since 1990. Although the urbanized area seems to have no specific direction and pattern regionally, it has regular direction and pattern when it is seen as a whole of the SMR. The development direction is closely related to the development condition. If we understand this relationship, we can predict the development direction.
