Urban Farm DB summary
This study established a GIS database of 508 sky gardens in Lanzhou, China, through image maps and on-site investigations, analyzing their spatial patterns and influencing factors. Sky gardens in Lanzhou showed spatial heterogeneity, with 82% being rooftop gardens, mostly on residential, mid- and low-rise buildings, often lacking public accessibility and having low vegetation coverage. Sky garden area was negatively correlated with building height and ground-level green area, and positively associated with plot ratio, building density, and population density. The study concluded that rooftop and podium utilization is relatively low, and sky garden development exhibits spatial clustering.
