The invention discloses a relationship map display method and device. The method comprises the following steps of: obtaining regional information of a local abstract map pointed by a navigation block in a navigation viewport; and mapping a local relationship map corresponding to the regional information of the local abstract map into a map display area through combining a display mapping proportion between the navigation block and the map display area, so as to obtain and display a local relationship map to be displayed into the map display area so that the local relationship map can be checked by users conveniently, wherein a one-to-one correspondence relationship exists among coordinate points in the abstract map, coordinates of elements in the relationship map and coordinates of the relationship. According to the method and device disclosed by the invention, the navigation viewport and navigation block combined use is realized, so that the users can check the to-be-checked areas in the relationship map in time and check the whole relationship map when the size of the navigation block covers the whole navigation viewport, thereby improving the relationship map check experience of the users and improving the display efficiency and display effect of the relationship map.
