The invention utilizes the network analysis function of ArcGIS software and combines with JAVA language to analyze the spatial accessibility of urban facility services. In order to achieve better spatial accessibility evaluation, the general research method is as follows : First, process the original data accordingly. Then, calculate the value of the transportation impedance, that is, the distance. The third step is to obtain the spatial accessibility by calculating the shortest distance matrix from the facility to the point of demand. Next, count the accessibility results. Finally, transform the data results into visualized images. According to the above steps, the accessibility analysis of urban facility services can make the results more accurate and avoid problems such as excessive error, insufficient reality or too subjective, so as to evaluate the rationality of urban facility layout and optimize it, which is conducive to the development of the city.
