Research on Spatial Accessibility of Public Service Facilities in Small Towns Based on Grid Method-A Case Study of Xuecheng Town

Based on GIS network and spatial analysis technology, grid cost-weighted distance analysis method is used to study the accessibility of public service facilities in Xuecheng Town. The research results show that the educational institutions' secondary schools, primary schools and kindergartens are concentrated in the West, and the educational institutions in the western regions have better accessibility; except for educational institutions, the rest of the administrative management culture, commercial financial and medical services are mainly concentrated in the northeast, and higher accessibility of public service facilities in the northeast. All kinds of service facilities do not match the residents' importance certification for service facilities, and the distribution of various public service facilities is unreasonable. The grid cost distance analysis method can directly and effectively reflect the spatial difference of the accessibility of public service facilities in small towns.
