Abstract Investigating the distributing pattern, the discipline concentration and decentralization of population are the foundations to make reasonable exploitation of resources, spatial development strategy, scientific population and urbanization policy of regions. A large number of researches have been studied at prefecture and county scales. However, researches of population spatial pattern at sub-county and a comparative of multiple scales seldom be investigated. This study use spatial statistics tools and data at prefecture, county and sub-county scales of Guanzhong-Tianshui economic zone to investigate the spatial-temporal pattern of population, influencing mechanism and differences at different scales. The principal findings of this study area are as follows:1) On the aspect of population spatial pattern, we find that Xi'an is the core of population distribution of the Zoneat prefecture scale, population mainly zonally distributes along Weihe River at county scale, population deceases along axis of the traffic line at sub-county scale. 2) On the aspect of population spatial pattern evolution, we find that population spatial distribution shows a significant trend of concentration in the region, the trend of population aggregation shows significant differences at different scales.Population aggregates towards Xi'an at prefecture scale and urban districts of prefecture city at county scale.
