摘要：The importance of blue-green space (BGS) in mitigating urban heat island effects is well established. However, how BGS accessibility and sustainability affect the thermal environment of residential areas is not well understood. This study determined this potential effect using BGS maps classified from 2013 WorldView-2 and 2019 BJ-2 high-resolution imagery and land-surface temperatures inverted using the thermal infrared spectral band of Landsat 8 OLI/TIRS products. In an urban area in Beijing, we defined BGS within and 300 m outside the residential area boundary as resident-accessible BGS, and the blue-green patch with no change in spatial location during 20132019 as sustainable BGS. We calculated the surface temperature and its change within the boundary. The study showed that 1) BGS accessibility was significantly associated with residential heat exposure, with BGS in the 300-m buffer zone having a stronger effect than that within the boundary; 2) BGS sustainability decreased the heat risk, and including blue and green elements promoted sustainability; and 3) although exposure in residential areas was decreasing, the gap between population density zones was aggravated. Recommendations for BGS planning are provided based on this heat riskadaptation gap. These findings provide new insights into thermal mitigation and adaptation strategies based on BGS. ? 2023, The Authors. All rights reserved.
