Study on Evaluation of Urban and Rural High-quality Living Space Based on Accessibility Analysis——Taking Shahe City, Hebei Province as an example

Abstract

The change of planning thought from “taking things as the center” to “taking people as the center” requires that the allocation mode of supporting public service facilities in urban and rural residential areas should also change from simple service radius to accessibility analysis. In this study, Dijkstra algorithm is used to analyze the spatial network with the help of the spatial data of urban transportation network and six types of public service facilities. Based on the concept of equalization of urban and rural public service facilities, this paper constructs an evaluation index system of high-quality living space of urban and rural residents based on accessibility, determines the weight by calculating the information entropy of each index, and compares and analyzes the accessibility evaluation results on the scale of urban and rural residential areas. Try to construct the full coverage and partial coverage of the 15-minute living circle of various facilities under four modes of driving at higher or lower speeds and walking for adults or the elderly. The research results show that the hardware construction of the city’s transportation network system and public service facilities is efficient and convenient, with high accessibility and accessibility, showing the characteristics of urban-rural equivalence. However, under the low speed and walking mode, there is still room for layout optimization and improvement of some road systems and facilities.
