Research On The Evaluation Of The Current Status Of Community Public Service Facilities In Xuzhou’s Old City From The Perspective Of Life Circles

The 2021 government work report pointed out that my country has entered an important period of urban renewal,and large-scale and disorderly incremental expansion obviously cannot adapt to the development of modern cities.It is urgent to adjust the incremental structure and improve the quality of stocks.At the same time,the plan is gradually becoming the basic governance unit of the community.penetration.The implementation of urban renewal will help to adapt to the new situation of urban development and promote the high-quality development of the city.Among them,the old city is the focus area in the implementation of the urban renewal action,and the optimization of community public service facilities is one of the important measures in the old urban renewal action.,Is an important engine that concerns people’s livelihood and enhances people’s well-being.Based on this,this article introduces the theory of living circles,takes the old city of Xuzhou as the research object,collects and processes six types of community public service facilities POI,uses Arc GIS 10.2 software to evaluate the status of community public service facilities,and delimits the old city community at the same time Life circle,and explore the optimization of the configuration of community public service facilities.The main research conclusions are as follows:(1)Evaluation of the status quo of community public service facilities in the old city of Xuzhou.This paper analyzes the balance evaluation,completeness evaluation and resident satisfaction evaluation of the public service facilities in the old city community,and concludes that the current public service facilities in the old city community have uneven distribution,insufficient facility coverage,large differences in street facilities,and residents’ satisfaction.Satisfaction generally has four questions.(2)Research on the delimitation of community life circle in Xuzhou Old City.According to the theory of living circle in "Design and Planning Standards for Urban Residential Areas"(GB20180-2018),use 15,10,and 5 minutes of travel time to construct a 15-minute shared living circle,a 10-minute neighbourhood living circle,and a 5-minute basic living circle;analyze residents Behavioral characteristics,surveying residents’ travel time and frequency of use,and finding that most people’s travel time is higher than the standard time and the acceptable time range of residents;at the same time,the standard of "land size + administrative boundary + residents’ willingness to travel" is used to delineate 25 There are 15-minute shared living circles,94 10-minute neighborhood living circles,and 244 5-minute basic living circles.(3)Research on the optimization of the allocation of public service facilities in the community in the old city of Xuzhou.Predict the demand for public service facilities,that is,estimate the size of the service population,and adopt the comprehensive growth rate method to obtain and modify the population forecast size of the 15,10,and 5 minute living circle in the next 5 or 10 years;according to the service population size and facility configuration System indicators,and considering objective factors such as the saturation of the old city’s land use and limited space,the scale of facilities can be reduced to enhance facility sharing and flexible configuration optimization;finally,from improving the management and control mechanism of the entire link,exploring a full range of guidance strategies and Three aspects of public participation in the whole process were improved.The paper has 70 maps,26 tables,and 86 references.
