摘要
城市人口老龄化这一城市人口长期变动趋势必然对城市未来居住空间演变产生重要影响。基于分层聚类法研究老龄化趋势是否诱导了城市局部空间的"集聚过程"或"浓缩过程"以及分析老龄化趋势对城市居住空间分异的作用过程。结论显示在高龄化后期,随着高龄人群的逐渐逝去和搬离,原来在"集聚"或"浓缩"作用机理下形成的居住空间开始逐渐"离散"。
Population aging is a long-time various trend in the city, which plays an important effect on the evolution of the urban residential space. This paper studied that whether happened ＂urban local space agglomeration process＂ or ＂urban local space concentration process＂ based on the hierarchical clustering method and analyzed the functional process of the aging trend towards the internal evolution mechanism of urban residential space. The results showed that with the elders passing away and migrating away the above ＂agglomeration process＂ or ＂concentration process＂ of urban residential space would gradually translate into ＂discrete process＂.
