Abstract: Aiming at the spatial arrangement of supporting facilities in the life circle theory, this paper combines expert experience and the spatial distribution information of supporting facilities resource points to give a method for determining the effective distance of supporting facilities. On the basis of constructing the index system of supporting resources for houses, the housing supporting facilities index within the effective distance is calculated. The index not only uses the Bayesian theory to determine the effective distance with objective data, but also uses distance quantiles and number differences to strengthen the discrimination between communities with similar supporting resources. An empirical analysis based on the Points of Interests data of Xiamen’s rental houses and their surrounding facilities resources shows that, the determined effective distance makes the spatial distribution of housing supporting resources index within the effective distance more like the normal distribution, and evaluates the abundance of supporting resources in each community more reasonably. The index could show the differences in demand frequency and demand preferences for different levels and types of supporting facilities better, and more accurately evaluate the available supporting facilities resources around the community where the house is located. The average levels of supporting resources around rental houses in Siming District and Huli District of Xiamen are better than those of the other four districts, but the level of equality is higher in Huli District and Jimei District. The research results could provide a basis for the scientific planning of locations and supporting facilities for the urban communities.
