Understanding the spatial interaction among residents, cooling service, and heat risk area in complex urban areas is conducive to developing targeted management. However, traditional thermal environment assessments typically relied on simply linear integration of associated indicators, often neglecting effect. To explore three elements, this study proposes an accessibility-based assessment framework. Using Zhengzhou, a rapidly urbanizing city, as example, remotely sensed images from periods (2010, 2015 2020) were applied extract green space (UGS) hot island (HIA). An improved two-step floating catchment (2SFCA) method bivariate local Moran' I employed whether residents clustering locations are more likely access service or be exposed risk. The results demonstrate that UGS city has been expanding, whereas HIA shrank within inner then increased 2020. Even though may last decade, could exacerbated. Spatial autocorrelation shows increase disadvantageous for resident congregation. when sufficient services provided, these still high developed framework provides novel insight into residents' exposure accessibility, findings assist planners targeting improvement extra locations.
