Potential evaluation for compound use of urban municipal infrastructure land in high-density cities: A case study in Shenzhen, China

As an important part of stockrenewal in high-density cities, the compound use urban municipal infrastructure land (UMICU) plays role improving efficiency land-resource utilization and mitigating not my backyard (NIMBY) effects. However, compared with reuse industrial other stock land, there have been few practical studies on UMICU. In this study, we proposed approach to evaluate UMICU potential from a city-scale perspective. A complete feasible workflow was also established define for UMICU, comprehensively analyze suitable directions, construct index system combining demand supply levels, quantitatively calculate indices based remote sensing (RS) geographic information (GIS), andaccurately evaluateUMICU using TOPSIS-MCS model derive priority each under different modes develop optimization strategies. case study Shenzhen, China, demonstrated applicability implications workflow. The results showed that can be subdivided into park renovation, commercial development, public-service compound, mode. area low-potential plots renovation mode accounted lowest percentage (1.7%), while development highest (36.5%). Under all four modes, high-potential Nanshan Street highest. method is flexible easy adapt local contexts, allowing evaluators introduce parameters considering availability data, will help decision-makers scientifically implement most effective which provides strong reference high-quality cities facing scarcity prominent NIMBY
