Based on the GIS spatial analysis technology, this paper assessed the effects of Nanchang metro in improving the accessibility of public transport networks in different spatial patterns. Besides, from the perspective of transport fairness, this paper evaluated the fairness of allocation of transportation resources for indemnificatory housing residents. Then, it revealed the reasons for the welfare loss of indemnificatory housing residents in fast rail transit resources, so as to provide a reference for promoting the space adaptation of indemnificatory housing residents. The study found that (i) the subway has improved the accessibility of the urban public transport network in terms of travel time and accessibility, but it has a different effect on improving the accessibility of the public transport network. After crossing a certain transit time and distance, there is a weakening trend, showing a pattern of "central expansion-peripheral weakness”. (ii) The relative improvement of the metro on the accessibility of public transport for indemnificatory housing residents is lower than the overall improvement efficiency, and the fairness of the redistribution of transportation resources of the indemnificatory housing residents is impaired. (iii) In order to prevent and reduce the problem of space mismatch between indemnificatory housing and rail transit, it can be achieved by planning the metro network according to the spatial characteristics of indemnificatory housing residents' activities, guiding the selection of sites for indemnificatory housing with the TOD model, and forming a mixed community by combining the indemnificatory housing construction with commercial housing, to guarantee fair resource allocation of indemnificatory housing residents.
