| 英文摘要 | Highlights What are the main findings? Nighttime light rose more rapidly than land surface temperature, with the strongest light-heat coupling in suburban zones and pronounced spatial heterogeneity across climate zones. Light-heat relationships exhibited a distance-decay pattern, showing synchronized increases in eastern coastal cities but decoupling in plateau and arid regions. What are the implications of the main findings? The results highlight the need for climate-specific adaptation strategies that consider local climatic and geographic contexts. The study provides a systematic quantification of urban-rural light-heat interactions across multiple climate zones, revealing spatial patterns previously underexplored.Highlights What are the main findings?

However, most existing studies have focused on single cities or relatively uniform climatic contexts, and the long-term dynamics between land surface temperature (LST) and nighttime light (NTL) across urban-rural gradients in diverse climates remain insufficiently explored. This gap limits a systematic understanding of how human activities and thermal environments co-evolve under varying regional conditions. To address this gap, we selected ten representative cities spanning multiple climate zones in China. Using MODIS LST and NTL datasets from 2000 to 2020, we developed an urban-rural gradient analysis framework to systematically assess the spatiotemporal response patterns and coupling mechanisms between LST and NTL. Our findings reveal the following: (1) From 2000 to 2020, NTL exhibited a pronounced upward trend across all climate zones, most notably in the marginal tropical humid region, while LST changes were relatively moderate. (2) LST and NTL displayed power-law distributions along urban-rural transects, marked by steep declines in monocentric cities and gradual transitions in polycentric cities, with sharper thermal gradients in northern and inland areas and more gradual transitions in southern and coastal regions. (3) The long-term increase in NTL was most evident in suburban areas (0.94 nW/cm2/sr/a), surpassing that in urban cores (0.68 nW/cm2/sr/a) and rural zones (0.60 nW/cm2/sr/a), with inland cities (0.84 nW/cm2/sr/a) outpacing their coastal counterparts. Although LST changes were modest, suburban warming (0.16 +/- 0.08 degrees C/a) was over twice that of urban and rural areas. Notably, the synergistic escalation of light and heat was most pronounced in tropical and subtropical cities. (4) Eastern coastal cities exhibited strongly synchronized rises in NTL and LST, whereas cities in the plateau, temperate semi-arid, and mid-temperate arid regions showed clear decoupling. Along urban-rural gradients, NTL-LST correlations generally weakened from urban centers to peripheries, yet coupling coordination peaked in fringe areas (mean = 0.63), underscoring pronounced spatial heterogeneity. This study advances our understanding of the spatiotemporal coupling of urban light and heat under varying climatic and urbanization contexts, offering critical insights into managing urban thermal environments. |
