Evolution of Hexi Corridor architectural spaces under climate change

This study examines how the traditional architecture of China’s Hexi Corridor adapted to its harsh arid, cold, and windy climate through thick earthen-wood composite walls, compact layouts, and enclosed courtyards. These elements not only reflect advanced vernacular construction techniques but also offer insights into past climate patterns and cultural exchanges along the Silk Road. By integrating the Mann-Kendall trend test with meteorological records, geographical analysis, and architectural typology, the study explores the evolving relationship between architectural development and climatic fluctuations from the Wei-Jin (220–420 CE) to the Ming-Qing (1368–1912 CE) periods. The findings provide quantitative evidence of how traditional structures adapted to environmental changes, offering valuable perspectives for both architectural heritage conservation and historical climatology research in the context of Silk Road studies.
