Abstract
The study on the factorial ecology of the residential patterns is to provide one of the yardsticks for description and comparison of urban structures. Many Korean geographers have adopted this method to analyse the urban structure of Korean cities. According to these studies, one of the main factors in Korean cities in large and middle sizes is family status. The spatial pattern of family status is zonal, similar to the cases of Japanese and Western cities. The age is one of the principal indices of familyf status, hence the author chose the age composition to analyse the residential patten. This Paper is to describe the residential segreagation pattern due to age composition and recent pattern changes in the Cheongju city, and than to explain the reason for these changes. All data are derived from the Population Censuses of Korea for 1970, 1980 and 1990. Eighteen groups of age with five-year interval (0-4, 5-9, 10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, 85- and- over) are adopted here. Unit area for this analysis is administrative district(Dong) within Cheonaju city. District are classified into smaller groups based on the similarity of age composition, using the method of cluster analysis. The main findings are summarized as follows: 1. Population have increased remarkably in the eastern reaion neighboring CBD of Cheongju city in 1970's. And in western region from CBD new residential area have developed in 1980's. 2. Spatial pattarns showed a concentric circle type in central district and its neighbor regions and a sector type in periphery regions in 1970; a cirele type in central district and a sector typesin neighbor regions and periphery regions in 1980 and 1990. Thess residential pattern play an important role in the population composition ratio of younger aged group (l5-34) and older aged group (65-and-over). 3. Spatial change of types by age composition showed the higher ratio of groups of 0-9 and 35-49, and lower ratio of group 20-24 in 1970's. Dominent groups are ratio of 0-14, 40-49, 55-64, 7O-79, and 85- and- over in 1980's. These changes mainly appeared in central district and periphery regions. 4. The reasons for the change of age composition was the development of msnufacturing industries with the increase of population and new construction of residential areas both in the neighbor regions of cnetral district and periphery regions. These phenomena were caused by immigration of younger aged groups and increasing of residents of aged groups in these regions.
1970-1990년 사이 연령별 인구구성비에 의한 청주시의 동 유형의 변화를 분석한 결과 다음과 같은 점이 밝혀졌다. \circled1 연령별 인구구성비에 의한 유형의 공간적 분포는, 1970 년에는 도심과 그 인접지역이 동심원패턴을, 주변지역은 선형패턴을 나타내었으나, 1980년에 는 도심의 인접지역과 주변지역이 선형패턴을 나타내었다. 1990년에는 도심과 그 인접지역 이 원형으로, 주변지역은 세분된 선형패턴으로 나타났다. \circled2 연령별 인구구성비에 의한 유형 의 변화는 1970년대에는 미학령 연령층과 35-49세의 장년충 인구구성비가, 1980년대에는 유.소년층과 40-49세, 55-64세의 장년층, 70-79세, 85세 이상 노년층의 연령구성비가 유형 의 공간적 변화를 가져왔다고 할 수 있다. 이와 같은 변화가 주로 나타난 지역은 도심과 주 변지역이다. \circled3 연령별 인구구성비에 의한 유형의 변화가 나타난 원인은 제조업의 발달로 인구가 증가함에 따라 도심의 인접지역이나 주변지역에 신흥 단독주택과 아파트가 많이 건 설되어 이들 지역에 청년층의 인구가 전입하여 본래 거주하고 있던 노년층과 혼재되었기 때 문이다.
