Abstract: Understanding the degree of interaction between microclimate and landscape risk in urban development is essential. This study analyzed the degree of interaction between microclimate and landscape ecological risk in 2000, 2010, and 2020 in the Xiahuayuan District in Zhangjiakou City, Hebei Province, China, using a coupled coordination degree model. The results show that the degree of landscape ecological risk in the Xiahuayuan District from 2000 to 2020 was mainly medium-high and high risk; the risk transfer area was 69.75 km 2 and 107.76 km 2 from 2000 to 2010 and 2010 to 2020, respectively. The surface temperature gradually decreased from west to east; the area of the middle temperate zone suitable for human habitation in 2000, 2010 and 2020 was 42.96%, 36.03% and 47.05%, respectively. The landscape ecological risk degree and surface temperature were closely related during the study period and interacted significantly. The coupling degree and coordination degree were dominated by high coupling degree and mutual coordination. The area of high coupling degree in 2000, 2010 and 2020 accounted for 79.53%, 78.07% and 85.06%, respectively; the area of mutual coordination degree accounted for 78.80%, 80.97% and 83.13%, respectively. The interaction between landscape ecological risk degree and surface temperature in the Xiahuayuan District was more evident, with strong coupling coordination.
