Abstrakt
Archaeological data from the Kushan period Bactria indicate rapid population growth, construction of complicated irrigation and water-supply systems, as well as founding of new and expanding of already existing towns and rural settlements. Large scale construction was impossible without a unified system of length measures.
The Kushans, being the descendants of Yuezhi nomads and thus lacking their own system, had to adopt it. The system in question can be traced not only in architecture, but also in the spatial distribution of the sites.
