A study on dweller's psychological condition and restructuring in decline or incomplete residential areas

本文研究了衰落或残缺居住区的现状，并探讨了未来居住区规划的概念。结果如下：1。对仙台市城郊衰落住宅区居民心理状况和土地利用变化进行了调查。结果如下：(a)区域特征对区域衰退状况有较大影响。(b)衰退地区居民的不安情绪较强。我们调查了仙台市老年人减少率较高的居住区的土地利用变化。结果表明，老年人口减少对城郊城市形态变化的影响强于城市中心区。我们对仙台市122个区1995 - 2040年的人口和家庭数量进行了估算。估算结果表明：(a)由于新住户的流入，城市中心区的户数减少幅度较小，但有许多地区的户数减少幅度较大，在郊区更为明显。(2)由于人口减少而产生的空置房屋或空置土地趋于闲置，需要新的管理制度。我们调查了目前人口达到最大水平一半的釜石市的人口和土地利用情况。结果表明，城市中心区的城市形态较为稳定，而近年来发展起来的城郊地区，由于人口的减少，空置房屋和空地迅速增加。我们开发了考虑生命活动时间的区域激活指标，并评估了每个区域当前和未来的激活水平。结果表明，老年人脑活化水平的升高并不直接意味着脑活化水平的下降。在考虑城市空间维护成本的基础上，建立了反映城市空间空间的指标，并对52个人口减少城市进行了评价。结果表明：随着人口的减少，城市空间的维护负荷越来越大，从城市空间维护的角度来看，部分城市空间出现了过剩。少

In this paper, we study current condition of decline or incomplete residential areas, also discuss about the concept of future district planning. Result is as follows ;1.We surveyed dweller's psychological condition and land use change in decline residential area located suburban area of Sendai City. Result is as follows ; (a)Characteristics of district has strong influence to decline condition of area. (b)Uneasiness of dwellers is strong in decline area.2.We surveyed land use change in residential area where decrease of elderly people is high, in Sendai City. As result, decrease of elderly people has stronger influence to change of urban form in suburban area than city central area.3.We estimate population and household number in 122 district in Sendai City, during 1995 to 2040. Estimation result shows that (a)Decrease of household number is rather gentle in city central area because of inflow of new households, but there are many district where decrease of household number is remarka … More ble, in suburban area.(b)The vacant house or vacant land which occurred by decrease of household number, tends to leave as used to be, so new management system is necessary.4.We surveyed population and land use in Kamaishi City where current population became half of the biggest level. Result shows that urban form is rather stable in city central area, but in suburban area where developed in recent years, vacant houses and vacant lots are rapidly increasing in connection to population decreasing.5.We develop the district activation indicator considering life activity time, and evaluate activation level of each districts in current and future. Results shows that increase of elderly people doesn't mean directly fall of activation level.6.We develop the indicator which shows room of city space considering maintenance cost of city space, and evaluate 52 population decreasing cities. Result shows load of maintenance city space becomes big in connection to population decreasing, and in some cities, space became surplus from a point of city space maintenance view. Less
