A comparative analysis of stone- and earth-wall settlement locations of the Lower Xiajiadian Culture in Aohan Banner, China

Abstract

Settlement systems are often characterized by a mixture of different site types, each with potentially different locational properties reflected by differences in their functions and uses. Prehistoric settlements in China are commonly known for their wooden defense structures and rammed earth. However, from the late Neolithic period, ca. 2800 BCE, a new type of stone-wall site emerged in northern China, coexisting with earth-wall sites. Examining differences in the locational properties of stone-wall and earth-wall settlements is essential for understanding regional settlement patterns and human–environment interactions in prehistoric northern China. Studies of this topic have so far been limited to descriptive qualitative accounts, and formal statistical comparisons of their differences have yet to be carried out. This paper contributes to this research agenda by examining, via point process models (PPMs), stone-wall and earth-wall sites associated with the Lower Xiajiadian Culture (2000–1400 BCE) in the Aohan Banner, northern China. We fitted log-linear and generalized additive models (GAMs) and identified the relevance of key spatial covariates via information criterion importance for both site types. Our results highlight not only the spatial preferences of stone-wall and earth-wall sites but also some differences, suggesting a defensive function of the former site type.
