Study On Residential Space Differentiation In The Main Urban Area Of Chengdu

Residential space provides the physical space basis for residents' activities and is also the spatial manifestation of residents' social settlement behavior.Its distribution has obvious clustering and differences,the differentiation of residential space will aggravate the isolation of urban residential space and the occurrence of social contradictions.Chengdu is an important central city in Southwest China.The city scale continues to grow and the residential space differentiation phenomenon appears.Taking the main urban area of Chengdu City as the research object,and on the basis of defining the research framework and systematically combing the domestic and foreign theories,it uses empirical methods to explore the situation of residential space differentiation and enrich the research cases of urban residential space in China,which has corresponding research significance.First of all,this thesis analyzes the current situation of cases of five communities in the main urban areas of Chengdu City through field research,and relevant data are obtained,Also,this thesis analyzes the differences of residents in different environmental and socio-economic levels from a microscopic perspective,reflecting the differentiation of social strata from the levels of public service facilities information,residential management,residents' satisfaction,population structure,economic level and employment situation.Among the five communities being analyzed,the medium or high-grade residential communities have good living conditions and complete public service facilities,and the community management is relatively perfect;while the low-grade residential communities even face the fate of renovation and demolition.The residents of the villages in the city and relocated houses pay more attention to neighborhood communication,and the residents' composition is relatively stable,while residents of medium or high-grade commercial housing are relatively indifferent to neighborhood communication,and the residents' structure is not stable enough.Secondly,based on the data collected in the Sixth National Census,this thesis takes streets as the unit,analyzes the situation and types of residential space differentiation in the main urban areas of Chengdu City from a macro perspective,tests and adjusts 54 variables repeatedly through factor ecological analysis,and finally selects 35 related secondary variables.The attributes are classified as primary variables of household type,age structure,ethnic structure,population mobility,educational background structure,industry structure,occupation structure,housing source,housing cost and housing conditions.In the factor analysis process,the main factors are determined as five according to KMO and Bartlett test values,total variance table and gravel map.According to the characteristics of the rotated component matrix,the main factors are respectively named as industrial development and migrant workers factor,retired personnel and white collar factor,ethnic minority factor,high-knowledge people factor as well as farmer factor.Thirdly,according to the five main factor variables corresponding to 72 streets,the variable values of the 72*5 matrix are systematically clustered and analyzed,and main urban areas of Chengdu City are divided into six categories,namely the tertiary industry and white-collar areas,retired population and elderly population areas,migrant workers areas,ethnic minorities areas,intellectuals areas and diversified agricultural areas.Among these areas,the tertiary industry and white-collar areas are concentrated in the center of the main urban area and distributed in a pie shape,with a multi-core distribution pattern in the north,northwest and southeast.Retired population and old age groups are mainly distributed in a circular pattern and extend toward the Southeast of the main urban area.The concentration areas of migrant workers are mainly scattered.Ethnic minority areas are mainly concentrated in Jiangxi Street,Wuhou district and scattered in other spatial directions.The high-knowledge people clusters are scattered in the central position of the main urban area and are fan-shaped in the Northeast and Northwest directions.Diversified agricultural clusters are scattered in the Northeast,Northwest and Southeast of the outer ring of the main urban area.Finally,according to the results from the empirical analysis,the problems of residential space differentiation in the main urban areas of Chengdu City are concluded,including: Multi-core concentration of high-class population and marginalization of low-class population;The development of the overall industrial layout is unbalanced;The degree of aging in the old urban areas has increased;Deterioration of living conditions of vulnerable groups;The composition of the residents is unstable and the neighborhood relationship is weakened.According to these existing problems,the corresponding countermeasures are put forward,namely,improve the level of urban planning and optimize the living space pattern;Reasonable industrial layout,give full play to the industrial advantages of each district;Moderately mixed living;Establishing a new type of neighborhood relationship;Improving the housing problem of vulnerable groups.Through this kind of research,we can understand the differentiation of residential space in the main urban areas of Chengdu City in a more comprehensive and reasonable way.And also this thesis serves as the research basis for narrowing the differentiation of residential space.
