A navigation environment establishing method for an intelligent moving-assistance apparatus moving in a movement area having a plurality of regions includes steps of: a navigation map is set, and the content of the navigation map including the relative locality of the regions. A current data indicating a current region is set. At least one target data indicating an available target region is set. Then, a navigation data is generated. The content of the navigation data includes the current region and a first target region, wherein the region where the intelligent moving-assistance apparatus first arrive when moving from the current region to the first target region according to a predetermined path is in a first direction with respect to the current region. Subsequently, the navigation data is recorded into an image identification tag. Finally, the image identification tag is placed in the current region.
