The　purpose　of　this　article　is　to　explore　the　impact　of　different　plan　form　of　circulation　systems　on　spatial　information　processing　and　orientation　abilities　of　newcomers　in　unfamiliar　large-scale　commercial　environments.　Two　shopping　malls　in　Beijing　were　chosen　to　apply　the　same　field　experiments,　which　were　in　the　same　conditions　except　different　types　of　circulation　systems---one　with　multi-atriums　and　linear　serial　type　of　circulation　system　and　the　other　with　single-atrium　centric　radiation　type　of　circulation　system.　Space　transition　nodes　from　horizontal　route　to　vertical　route　in　each　circulation　system　were　various　as　well.　A　total　of　69　participants　were　divided　randomly　into　two　groups　and　complete　4　separate　tasks　to　explore　the　correlation　between　different　types　of　circulation　systems　and　space　orientation　performance.　Personal　difference　in　cognitive　styles　and　spatial　abilities　were　examined　as　well　to　explore　the　correlation　with　space　orientation　behavior.　The　main　conclusion　was　that　performance　of　space　cognition　tasks　of　space　users　in　multi-atriums　and　linear　serial　type　of　circulation　system　is　superior　to　single-atrium　centric　radiation　type　of　circulation　system.　Cognitive　style　of　space　users　was　correlated　with　performance　in　space　cognitive　sketch-map　tasks　and　the　answers　to　a　questionnaire.
