Research On The Service Facilities Allocation Of Community Life Circle In The Urban-Rural Fringe Of Wuhan City

With the continuous development of Chinese people-oriented new urbanization,the focus of territorial space planning has shifted from incremental space to inventory space,and planning research has placed more emphasis on shaping the daily living space of residents,that is,the community life circle.This study aims at the lack of attention to the urban-rural fringe as a transitional area in the current planning guidelines for community life circles and related research,which has affected the improvement of the quality of life of residents in the fringe and the advancement of the urban-rural integration process.Taking Wuhan City as an example,a real urban-rural fringe in Wuhan City was delineated using fusion data of nighttime lighting(NTL)and electronic map points of interest(POI),Select the network analysis method in GIS to construct the community life circle range in the urban-rural fringe under three travel scenarios of walking,cycling,and electric vehicles,and analyze the fairness,convenience,and matching degree of its service facilities with population density.After summarizing the current characteristics and problems of the allocation of community life circle service facilities in the urban-rural fringe,the author constructs a recommendation system for the allocation of community life circle service facilities at three levels,namely,primary,basic,and shared,from the perspectives of "selfsufficiency","integrity",and "sharing",and proposes zoning optimization strategies based on the spatial mismatch between population and facility convenience.The main research conclusions are as follows:(1)The fusion data of NTL and POI can accurately identify the boundary between urban and rural areas in Wuhan,with a value lower than 0.1 in the urban-rural fringe,and the contour enclosing area shows a sharp increase between the junction and the countryside.NPP&POI can integrate the differences in facility type,light intensity,and resolution between NTL and POI,resulting in higher accuracy and timeliness compared to identifying urban and rural junction areas using NTL or POI alone;The total area of the urban-rural fringe in Wuhan City is 1482.35 km 2,Accounting for 17.30% of the total area of the city,with a population density of 2556.28 people/km 2,It is significantly lower than the urban core area,accounting for 27.46% of the population in Wuhan.(2)The allocation of basic transportation,daily shopping and living,basic medical care,and primary education services in the community life circle at the urban-rural fringe of Wuhan City is relatively good,while the allocation of public cultural and leisure,sports,and elderly care services,as well as large-scale medical and shopping facilities is unsatisfactory.Areas with poor accessibility are mainly distributed around large rivers and lakes,such as the Yangtze River,the north bank of Houhu Lake,and the east bank of East Lake,administrative junction areas such as the junction of Tianhe and Hengdian streets,the junction of Yangluo and Wuhu streets,the periphery of new city clusters such as Shamao,Caidian,Qianchuan,and Zhucheng,industrial parks such as Jingang New District,areas under development and construction such as Huashan West and Zuoling Future Science and Technology City,and areas with broken residential plots such as the east of Bajifu Street and the south of Qingling Street.(3)The overall spatial mismatch between population density and convenience of service facilities in the community life circle at the urban-rural fringe of Wuhan City is relatively light.Areas with population density ahead of facility development are mainly located in the northeast of Jiang’an District,the middle east of Qingshan District,most of Hongshan District,the southwest of Xinzhou District,the north of Jiangxia District,the southwest of Hanyang District,the east of Dongxihu District,the northeast of Caidian District,Hannan District,and the south of Huangpi District.In terms of life,education,culture,sports The lack of leisure and elderly care facilities is a prominent issue,and it is an area that needs to be focused on in future planning and construction.The areas with relatively balanced population density and facility allocation are mainly located in the south of Huangpi District,the north of Yangluo,the north of Jiangxia District,Changfu,Daji,Sino French Ecological New Cities in Caidian District,Zoumaling and Jinghe Modern Intelligent Manufacturing Areas in Dongxihu District.There is still considerable room for improvement in leisure and elderly care services.(4)The key optimization areas of the community life circle in the urban-rural fringe of Wuhan City are mainly located in the central part of Qingshan District and the western part of Hongshan District.The primary circle focuses on strengthening the fair allocation of kindergarten,primary school,sports,leisure,and elderly services in the eastern part of Bajifu Street,while the basic circle focuses on improving the coverage of nine-year regular schools.The sharing circle needs to strengthen sharing with large hospitals and nursing homes in the urban core area.The secondary key optimization zone is mainly located in the majority of Hongshan District,Zhucheng,Qianchuan,and the periphery of Shamao.The primary circle focuses on strengthening the construction of slow traffic networks,improving the compliance rate of medical,living,and educational facilities,adding junior high school,market,and other facilities as appropriate to the basic circle,strengthening the allocation of nursing homes in Shekou,Dongjing,and other places in the sharing circle,and appropriately tilting large-scale cultural and shopping facilities to new areas such as Changjiang New City.The general optimization area is mainly located in Linkong New City,north of Yangluo and Zhengdian,east of Miaoshan and Caidian,and other places.Facilities can be selected based on population conditions.The elderly population in this area is relatively small,and the allocation plan for elderly care homes should be formulated based on the prediction of population age structure.The demonstration and leading areas are mainly located in the center of Tianhe and Hengdian Street towns,Wutong District of Changjiang New City,Optics Valley Science City,Changfu,and other places.The primary circle should appropriately supplement kindergartens,primary schools,leisure,cultural,and elderly care facilities.The basic circle should focus on improving the coverage of nineyear consistent schools and leisure facilities.The sharing circle should focus on providing large-scale,high-quality,and diverse shopping,elderly care,and medical facilities.
