The allocation of public services in urban communities is pivotal for both the residents' quality of life and the promotion of social equity. Particularly in mountainous resource-based cities, unique land-use conditions and urban morphologies critically influence the efficacy of urban public service distribution. Recognizing these land-use peculiarities can indeed catalyse the adaptive allocation of public service resources, especially in shrinking cities. This study uses GIS spatial analysis and SPSS statistical methods to explore in depth how urban morphology affects the differences in the allocation of community public service facilities in resource-based mountainous cities, taking Benxi City in Northeast China as an example. The findings indicate that the disparities in community public service provision are primarily associated with the attributes of the communities. Specifically, communities with commercial housing have markedly superior public service facilities compared to those with subsidized housing, high-income commercial housing communities which have a more advantageous provision than middle and low-income counterparts. The level of community public service facility provision is closely linked with the spatial structure of resource-based mountainous cities. For instance, newly established urban areas have evidently better public service provisions than traditional central urban areas, while aging mining areas tend to have relatively poorer provisions. Although the specific morphology of mountainous cities does constrain urban development to some extent, it appears that in resource-based mountainous cities, these mountainous characteristics do not significantly limit the open boundaries of communities. Lastly, the study found that communities in different urban areas display pronounced differences in service facility provision, which is intricately related to the spatial distribution patterns of various facilities.
