Abstract: As the core content of community life circle, public service facilities directly determine the level of life quality of community life circle. How to quantitatively evaluate the construction of community public service facilities and provide scientific decision support for the future planning of facility construction has gradually become a major problem for planners and decision-makers. In this study,POI data is processed, counted and visualized by ArcGIS tool. On the basis of summarizing the quantitative evaluation methods of other people's community living circles, a set of evaluation model of public service facilities in community living circles is built by combining the local characteristics of Wenzhou. The model can be used to comprehensively score and grade various communities, and the future optimization direction of public service facilities can be mined according to the model scoring results. In addition, this study realizes the dynamic calculation and display of community living circle score, and provides decision support for the site selection of community service facility construction, road network construction and priority assessment of public service facility construction. This study can not only help planners and decision makers to quickly establish a quantitative understanding of the current situation of the entire regional living circle construction, but also help to optimize the allocation of public service facilities, and explore new ideas and methods for the evaluation and improvement of public service quality in community living circle.

Key words: community life circle, public service facility, evaluation model, dynamic scoring, optimal allocation
