摘　　要：随着中国城镇住房制度改革的推行,城市内迁居行为日趋频繁。洞悉不同年龄段居民迁居内在驱动力,能为城市居住环境规划与建设改善提供依据。论文利用2019年与2021年武汉市手机信令等多源数据,以生命周期理论为研究视角,识别武汉市四环内不同年龄段居民交通小区迁居强度,并提出建成环境因子特性与迁居强度关系模型,探讨居民生活圈内各建成环境因子对多年龄段居民迁居影响的特性差异。研究发现:①不同年龄居民的迁入与迁出强度在不同城市区位上存在分异,19~39岁居民相较于40岁以上居民迁居更频繁;总体呈现内环线的交通小区迁入与迁出强度表征偏高,且均大于外环线的交通小区。②公共服务设施、交通便利度和居住环境维度内相关指标是影响居民迁居决策的重要因素,由于不同年龄段居民居住需求不同,部分变量因子在不同年龄段下特性分异明显。考虑到各年龄段居民迁居强度及因子特性不一,相关规划决策需采取差异化的建成环境改善措施,科学引导不同年龄居民迁居,优化城市人口分布。With the reform of China's urban housing system,relocation in cities is becoming increasingly more frequent.Analyzing the internal driving forces of residents of different age groups to move provides a basis for the improvement of urban living environment planning and construction.This study used multi-source data such as mobile phone signaling data in Wuhan City in 2019 and 2021 and took the life cycle perspective to identify the relocation frequency of residents of different age groups within the Fourth Ring Road of Wuhan City.This study proposed a model of relationship between the characteristics of built environment factors and the frequency of relocation,and explored the impact of various built environment factors in the residents'living circles on the relocation of residents of multiple ages.The study found that:1)The moving in and out intensities of residents of different ages varied in different urban locations.Residents aged 19-39 moved more frequently than residents aged over 40.In general,the moving in and out intensity of the traffic areas within the inner ring road is high,and both are larger than those between the outer ring roads.2)Relevant indicators in the dimensions of public service facilities,transportation convenience,and the living environment are important factors that caused residents'decision to move.Considering the differences in the relocation intensity of residents of different age groups and the characteristics of influencing factors,relevant planning decisions need to incorporate differentiated measures to improve the built environment,scientifically guide residents of different ages to relocate,and optimize urban population distribution.
