兰州市家庭规模和结构时空演变特征及影响因素分析——基于“五普”和“六普”数据的比较

Analysis of Spatial and Temporal Evolution Characteristics and Influencing Factors of Family Size and Structure in Lanzhou City——Based on the Comparison of the Fifth and Sixth Censuses Data

基于2000年和2010年的全国人口普查数据,对兰州市家庭规模和家庭结构的时空演变特征进行了分析。十年间,兰州市家庭规模小型化、结构简单化的特征明显,空间上表现为小型户和一代户家庭街区范围不断扩大,中、大型和二代户及三代及以上户家庭街区范围不断缩小。在空间集聚上,各家庭类型的空间集聚范围发生了较为明显的变化,但其格局相对稳定,基本保持和延续着"核心-外围"的圈层结构特征。影响兰州市家庭规模结构时空变化的主要因素有:计划生育政策导致的生育率下降;家庭生命周期的变化;社会经济发展及人口流动;社会不断进步带来的婚姻观、生育观和价值观的转变。

Based on the data of National Population Censuses of 2000 and 2010,the temporal and spatial evolution characteristics of family size and family structure in Lanzhou are analyzed.The results show that in the past ten years,the family size of Lanzhou has been miniaturized and the structure has been simplified obviously,and the space is characterized by the expansion of the scope of small and first-generation family blocks. Large and second-generation households and third-generation and above households continue to narrow the scope of family blocks. In the spatial agglomeration,the spatial agglomeration scope of each family type has changed obviously,but its pattern is relatively stable,and basically maintains and continues the"core-periphery"circle structure characteristics. The main factors affecting the temporal and spatial changes of family size structure in Lanzhou are: the decline of fertility rate caused by family planning policy,the change of family life cycle,Socio-economic development and population mobility,and the large-scale population movement caused by social and economic development. The transformation of marriage view,fertility view and values brought about by the continuous progress of society.
