... re still disputes on how to guide the regeneration of resettlement areas in different urban conditions effectively. We try to introduce the method of spatial analysis using GIS to evaluate the existing 176 resettlement communities we found in Suzhou Metropolitan Area. We classified the resettlement communities into four categories upon multiple factors, which could be assessed using the densification concept's index weight. According to the matching degree of overall property value and construction intensity, and put forward relevant regeneration strategies. At the same time, the feasibility assessment is verified in combination with the comprehensive regeneration plan from the government in recent years. The results show the current government's reconstruction focuses on low-density and below the medium housing prize communities, which is also the lowest grade in the previous assessment. We encourage these communities could be regenerated by reconstruction, demolition, and reconstruction simultaneously, gradually increasing the density and accessibility and enhancing public services. The study also attempts to discuss the corresponding regeneration strategies for the other three types of resettlement areas. This research of resettlement communities in the Suzhou Metropolitan area can further promote urban regeneration policies and guidelines for sustainable design intervention.
