Research On The Layout Of Community Public Service Facilities From The Perspective Of Vitality

With the continuous development of the society,and the living standard of the residents is gradually improving,it is difficult for the scattered spatial layout of the current community public service facilities to effectively carry the functions of the community,and the demand for material culture is becoming more and more intense.As one of the most basic community cultural facilities,the community library is an important communication platform of the community and one of the important source of community vitality,which is closely related to people's daily life.At present,many community libraries in our country are conflicting with the daily activities of residents due to the single service content and poor location.As a result,they gradually lose their attraction and vitality to residents and perform practically no function of supporting facilities.At present,the academic circle has done more research on the spatial layout of community public service facilities,but there are few academic achievements on the spatial layout of facilities from the perspective of vitality.The vitality around the facilities is directly related to the use efficiency of the facilities,and also reflects the convenience of daily use of residents.This paper takes Shenzhen community library as the research object,takes the urban spatial vitality as the research perspective,and analyzes the development status,spatial layout characteristics and aggregation with other community public service facilities of Shenzhen community library by combining field investigation,GIS,mathematical statistics,and other means;On the basis of the construction of the evaluation index system of vitality,this paper measures the surrounding vitality of Shenzhen community libraries,excavates the constitutive elements of sensitivity and dullness of the surrounding vitality of the community library,and provides strategies for the optimizing of the layout of the community library,so as to further provide reference for the feasibility of building the community center.The study finds that the spatial distribution of community libraries in Shenzhen is unbalanced and unfair.Some community libraries and other community public service facilities are scattered among each other,which is not matched with the daily activities of the population.Therefore,it is needed to adjust the corresponding spatial layout.Furthermore,the surrounding vitality of the community library is measured.To excavate the intensive scale of the space,the block fabrics,and the functional density,which are the sensitive factors affecting the surrounding vitality of the community library.Traffic accessibility and the location of community facilities are the retarded elements,and the factors affecting the vitality of the community library under different community natures will be different.It should be fully considered these factors in the site selection of the community library.In addition,the social health center can serve as an important reference for the site selection of the community library.Finally,the community library with "community center" as the layout of the new model is an important development direction in the future.The innovations of this paper are mainly shown as follows: firstly,it uses a variety of spatial analysis methods,and perfects the quantitative research on the spatial layout of community libraries;secondly,the quantitative relationship between physical environment characteristics and crowd activities was established,it measures the surrounding vitality of community libraries and improves the research on the micro-level spatial vitality;thirdly,the combination of vitality improvement and layout optimization provides a new perspective for the research on the layout of community public service facilities.
