Urban high-temperature disasters have gradually emerged as a significant threat to human society. Therefore, it is crucial assess and identify areas at risk of such implement urban planning measures aimed mitigating their impact. Additionally, multitude studies demonstrated the cooling effect blue-green spaces (UGBS), which play pivotal role in environments. Incorporating UBGS layout into evaluation processes has substantial potential for disasters. This paper presents construction set assessment disaster using structure specifically main area Harbin, China. We employed GIS multi-source remote sensing imagery develop local climate zone (LCZ) maps applicable designated study area. The differentiated impact factors on was determined multi-scale geographical weighted regression model (MGWR). results showed following: (a) There an overall low level, with 19.61% high-risk concentrated within second ring road, forming spatial pattern characterized by “one line, one cluster”. (b) building category LCZs generally higher than that natural LCZs. architectural could be summarized low-density being smaller high-density LCZs, except LCZ 5. mean value 2 5 types highest. (c) Through indicator screening, AREA_MN, SHAPE_MN, PD, NP were found determinants influencing risk, effectiveness differentiation these exhibited notable disparities. (d) By comparing different types, we concluded mitigation may interfered height (BH); positively BH; PD SHAPE_MN negatively BH. research provided new perspective practical scientific basis risk-mitigation based UBGSs under classification.

Green infrastructure (GI) can act as an effective cooling strategy to mitigate the urban heat island effect. The complex interdependencies in built environment make it challenging quantify GI accurately. Present literature on often lacks focus techniques and overlooks co-benefits. This review addresses this gap by consolidating recent research standard design approaches maximize cooling. temperature results from are segregated type, technique local climate zones, scale. ENVI-met Weather Research Forecasting model (WRF) most common numerical modeling methods utilized for microscale mesoscale. Results indicate that highest air reduction is achieved arid climates, followed temperate, tropical, continental respectively. study suggests integrate into successfully, researchers should consider influencing factors like spatial distribution, microclimate, plant selection. Climate change intensifies severity of overheating; therefore, integrating cities must be done holistically co-benefits related trade-offs.

Abstract Context Urban parks are essential for maintaining aesthetics within cities and keeping their its energy balance by helping mitigate the Heat Island (UHI) effect through controlling ambient land surface temperature (LST). Objectives To investigate impact of cooling in terms distance variously configured urban a humid subtropical city, using landscape metrics open-source data. Methods Land use (LU) was obtained maximum likelihood classification 3 m resolution aerial RGB-NIR imagery supported ground control points park boundaries collected during field survey. LST at matching downscaling Landsat-8 30/100m resolution, calculated with Radiative Transfer Equation (RTE). Landscape patches were landscapemetrics R library related to neighbourhood distances over built-up (LU). Results homogenous cores less complex shape provide distinctly higher neighbouring LU circa 2.55 °C 18 from boundaries. Four metrics: contiguity index (CONTIG), core area (CAI), fractal dimension (FRAC) perimeter-area ratio (PARA) represent significant relationship between spatial configuration distance. No capacity regardless observed beyond m, which remained constant small fluctuations range 0.5 up 600 m. Conclusions The study concludes that extends is shorter than suggested other studies.
