The Ancient Silk Road was one of the most important passages for trans-Eurasia exchange and human migration, which witnessed the rise and fall of ancient civilizations in Central Eurasia. In the central part of the Ancient Silk Road, where the climate condition is extremely dry and the ecosystem is very fragile. The climate and environment changes, especially the water resources change in this area, can significantly influence the spatio-temporal distribution of Ancient Silk Road network, the trans-Eurasia exchange and human migration along the Ancient Silk Road, and the civilization evolution of these ancient cities and towns among the Ancient Silk Road network. This session aims to explore the history of trans-Eurasia exchange, human migration, Ancient Silk Road network spatial change, civilization evolution and climate and environment change, as well as relationship among them in the areas along the Ancient Silk Road. We welcome presentations concerning these issues from multi-disciplinary perspectives, to promote the advancements of research in the field.
