Study On The Evaluation Of The Life Convenience Of Typical Differentiated Communities From The Perspective Of Life Circle

With the rapid progress of urbanization,regional differences have emerged year by year and formed spatial differences,causing a series of urban problems.From the perspective of residents' daily life,it is the spatial differentiation of residential communities and the uneven spatial distribution of surrounding public service facilities,which virtually aggravates the social differentiation.In order to improve the livability of cities and promote the healthy and harmonious development of the society,cities begin to study the configuration of public service facilities in the life circle.As an important indicator to measure the livability of a city and the rationality of the spatial allocation of urban public service facilities,the previous studies mostly stayed at the urban level,mostly evaluating the living convenience of urban residents according to the overall situation of urban public service facilities construction.However,due to the objective existence of the differentiation of urban living space,the distribution of public service facilities is not balanced and sufficient in space,and the daily life convenience of residents in different regions of the same city is different.This paper introduces the convenience of life into the study of life circle,explores the convenience of daily life of residents in differentiated communities,understands the impact and difference of the differentiation of urban living space on the daily life of residents,and provides some reference for the balanced allocation of urban public service facilities and urban renewal.Chengdu center optimization district is an important area for improving the urban quality of Chengdu.Studying the convenience degree of its residents' daily life is conducive to understanding the rationality of the spatial arrangement of various facilities and providing some Suggestions for the construction of Chengdu national livable park.In this paper,based on the perspective of life circle,with optimal in the Chengdu area as the research scope,POI data using the network,through the GIS spatial analysis,selecting typical differentiation community as the research object,based on the index evaluation method for index on foot,building the appraisal model of residents' daily life convenience,this study district in Chengdu residents daily life convenience.It is hoped that the convenience index of daily life can reflect the convenience degree of residents' walking to get basic service facilities within the scope of daily life and the spatial rationality of service facility configuration.Since housing price and housing type are important characterization factors of urban residential space differentiation,this study conducts a classified study on residential buildings based on the sales price and type of residential areas to explore the daily life convenience of residents in different types of residential buildings in the superior urban area of Chengdu.The main conclusions are as follows:(1)Various types of residential differentiation exists in the space,affordable housing and villas are mainly distributed around the third ring road,the ordinary plot divided by price interval has higher spatial mixing degree,but has obvious positive correlation in space,and shows the state of aggregation of high-price and high-price plot,the low-price area accounted for a relatively high distribution,the low price mainly outside the third ring road.(2)The convenience of daily life of residents in center optimization district of Chengdu is relatively convenient on the whole,however,it shows the characteristics of " ordinary community > villa > indemnificatory housing ".In the study of typical streets,the convenience of daily life of residents of typical high-price mixed streets located in high-tech development zones and typical low-price streets outside the third ring road are obviously lower than other types.Low-income housing residents have the lowest convenience in daily life,and they lack most of infrastructure in daily life.(3)Most of the daily life service facilities are convenient for daily use,but the park,shopping center and pension service institutions are not evenly distributed in space,and the daily use convenience of residents is poor.
