The existing literature indicates a considerable linkage between surface urban heat island (SUHI) or land surface temperature (LST) and urban landscape patterns (ULPs). However, how and to what extent the ULPs influence SUHIs/LST remain a subject of debate, and insufficient attention has been paid to vertical ULPs and variations in their thermal effects over space and time. Furthermore, technical inadequacies and oversimplifications inherited in the SUHI conceptualization cause huge uncertainties in current measurements. A multi-scale study on the ULP-LST/SUHI linkages was conducted in the Chinese context. This study (1) develops a two-step estimation approach to reduce part of biases and uncertainties in SUHI estimation and unveils the spatiotemporal characteristics of SUHI in 283 cities; (2) proposes a three-level quantification framework for ULPs based on two-dimensional and three-dimensional spatial metrics; (3) identifies time- and space-varying relationships between ULPs and LST at street block level across 38 big cities; (4) examines the effects of surrounding ULPs on LST and identifies the influence ranges of key ULPs.
