Analysis of Spatial-Functional Correlations between Public Facilities in Yazd City

With regard to the key effects that spatial-functional correlations between urban public facilities have on the quality of urban life, the aim of this article was to analyze the correlations between public facilities in Yazd city. To do this, four different methods, including the nearest neighbor index, K-Ripley function, spatial correlation index and analysis of variance (ANOVA) for two different groups of facilities including homogeneous public facilities and heterogeneous public facilities have been carried out in this article. Results have shown that although facilities such as technical and vocational training centers and public health services have shown a clustered pattern according to the nearest neighbor index, as the K-Ripley function has indicated, their distribution does not follow the same pattern at different scales of analysis. The analysis of the spatial correlation between the distribution of population and the distribution of public facilities has also shown that there is a negative correlation between them, except hygenic facilities. In addition, as the analysis of the spatial correlation between heterogeneous facilities has shown, except the correlation between higher education facilities and sports facilities, there was a positive but not strong relationship between all of them. Finally, it has been argued, according to the ANOVA method, that the high values of spatial correlation between heterogeneous public facilities do not necessarily mean that they are close to each other spatially.
