Research On Optimization Strategies Of Supporting Facilities In Community Life Circle From The Perspective Of Residents’Demand

With the overall transformation of China’s economic and social development mode,the focus of urban planning has also shifted from incremental space to inventory space,and planning research has increasingly focused on grassroots communities.In view of the disconnection between the change of residents’ living demand and the supply of service facilities,the new edition of the standard for planning and design of urban residential areas puts forward the requirements for the allocation of facilities based on the community living circle and within walking distance.Under the background of the implementation of new standards and requirements,it is urgent to check the coverage of supporting facilities in inventory communities,so as to find out problems and formulate optimization strategies.Based on this,this paper takes xi ’an yanta district as the research object,first of all,on the basis of residential AOI face data and facilities POI point data,using GIS spatial analysis,analysis of the basic education,health care,entertainment,business services,pension service,transportation service supply characteristics of six class facilities,summarizes present situation problems and analyze its influencing factors.Secondly,the daily behavior characteristics and demand preference of residents are analyzed according to the questionnaire survey data.The difference between the standard rate of facility use and the standard rate of supply is analyzed by using the comparative analysis method,and the contradiction between supply and demand is summarized and the influencing factors are analyzed.Finally,the paper constructs the supporting facilities system of community life circle,and puts forward the optimization strategy of supporting facilities of community life circle from three aspects of improving supply,matching demand and planning guidance.The main conclusions are as follows:(1)The spatial distribution characteristics of different types of community supporting facilities in the study area are obvious.Among them,basic education facilities are closely related to population distribution,which is affected by urban functional layout and has poor overall balance.The east-west distribution of medical and health facilities is extremely uneven,and the density in the west of the city is too low.The distribution density of recreational facilities decreases from the center to the periphery with a higher degree of spatial concentration.The density of commercial service facilities in the east is lower than that in the west.The number of old-age care institutions is small and the coverage is small,so the community old-age care facilities need to be improved urgently.The spatial distribution of traffic service facilities is balanced.(2)In the study area,there is a supply gap in the space and type of community supporting facilities,and there is a significant difference between different residential areas and different types of facilities,so the facility compliance rate needs to be improved.From the perspective of the type of facilities,it is necessary to focus on improving the standard rate of supply of primary and secondary schools,kindergartens and cultural places,especially elderly service facilities.From the perspective of residential types,it is necessary to focus on improving the standard rate of facility supply in affordable housing residential areas.From the perspective of residential location,it is necessary to focus on improving the recreational,recreational,commercial and traffic service facilities in urban fringe areas,as well as the standard supply rate of basic education and medical and health facilities in qujiang street.(3)The characteristics of residents’ daily behavior and their demand preference can be used as an important basis for facility allocation.High frequency,medium frequency and low frequency facilities are arranged in order from near to far according to the utilization frequency characteristics of facilities;According to residents’ preference for facilities,the supply or supplement of differentiated facilities should be fully combined with the characteristics of residential population.According to residents’ strong demand for walking in daily travel,the goal of facility configuration is to achieve walking distance,so that residents can obtain service facilities within walking space.According to the satisfaction degree of facilities and its influencing factors,in the optimization of facilities,problems such as difficulty in enrollment,poor medical level,incomplete service facilities for recreation,sports and commerce,insufficient facilities for elderly care,and too few traffic stations should be solved.(4)In daily activities of residents,the current travel time distance is higher than the standard and ideal travel time distance,the compliance rate of facilities is lower than that of supply,and there is a big difference.The daily travel distance is far greater than the supply distance of current facilities,and the contradiction between supply and demand of facilities is prominent.The reasons for the contradiction between supply and demand are the teaching quality,teaching environment and the limitation of entrance conditions of basic education facilities,except the insufficient supply of facilities themselves.The medical level of medical and health facilities;The service level,individual demand and environmental quality of recreational facilities and commercial service facilities are the factors that cause the contradiction between supply and demand.(5)The optimization strategy of supporting facilities in community life circle is carried out from three aspects of improving supply,matching demand and planning guidance.To improve the supply level,the supporting facilities should be fully covered by supplementing the supply gap,and the service system of various facilities should be improved by formulating promotion strategies based on stratification and classification.In terms of matching demand,it matches residents’ demand for high-quality basic education and medical and health facilities through balanced supply quality,and ADAPTS to residents’ diversified demand for entertainment,sports and commercial service facilities through diversified supply.At the planning and guidance level,combined with the building of open blocks,the community supporting facilities will be guided to realize comprehensive sharing.Through the continuous optimization of pedestrian traffic,the residents will be guided to change to a green and healthy way of travel.
